cutworm, wireworms, grubs, armyworms, etc. The samples have been deposited in the collection. couples) T2 (8 couples), T3 (16 couples) and T4 (20 couples). It is therefore likely that the sequestration of The order Meliolales comprises two families, namely, Armatellaceae and Meliolaceae. Orange trees can be heavily affected by insects (mainly aphids) and also by fungal, bacterial and virus diseases. The attack of pests and diseases results in a considerable reduction of the production potential of jatropha. Pseudocercospora bertholletiae is a new combination, while P. caesalpinigena and P. yeniana are two nomina nova. This has been due to lack of elite planting materials, poor agronomic practices and inadequate crop management systems. Some of pests and disease in Jatropha Curcas can be seen in Table I. (Homoptera: Aleyrodidae) is the vector of cassava mosaic geminiviruses (CMGs), which are the main production constraint to cassava [Manihot esculenta Crantz (Euphorbiaceae)], both in Uganda and elsewhere in Africa. Burkina Faso, Survey, Jatropha curcas, Natural Enemies, Calidea panaethiopica. Beetles were rarely found in the dry season and peaked in the second half of the rainy season. Microscopic examination revealed severe hyperplasia caused by JMV with a considerable reduction in the size of stem cells. The phorbol ester DHPB has been detected in 5th instars and adults of Pachycoris klugii which feed on Jatropha curcas, a producer of phorbol esters with mollusc-, insect-, and vertebrate toxicity. Pests and diseases do not pose a significant threat to jatropha due to the insecticidal and toxic properties of all parts of the plant. methods of control (which will be defined here as the use of living organisms to control insect pests), such as the use of fungi, viruses, bacteria, nematodes and autocidal control (e.g., sterile insect release), have many advantages over chemical control methods. Probably the most common peach tree fungus is Taphrina deformans, which causes peach tree leaf curl, sometimes referred to simply as leaf curl.This frustrating disease stunts the tree’s growth and severely hampers fruit production. The results Vestiges of the nymphal scent glands retained by the adult are described and discussed. seeds and the damage due to the insect pest. This chapter reviews the known insect natural enemies of major potato pests around the world: Coleoptera, including the Colorado potato beetle, hadda beetle and related lady beetles, the Andean potato weevil complex, Gelechiid tuber worms, the potato psyllid, and aphids. single J. curcas plant:T0 (control = no insect pest), T1 (4 No yield loss In contradiction of the general belief that J. curcas was resistant to pests because of its toxicity, a large number of insects and other pests have been identified that can severely reduce growth and yield (Anitha and Varaprasad 2012, Minengu et al. The two members of the fruit feeding guild led to premature fruit abortion and malformed seeds. In gel-diffusion serology tests, pronounced precipitation spurs developed between CLV-T and CLV-C indicating that the isolates were related but not identical serologically. It has been considered worldwide an important source of seed oil for the production of biofuel; however, this crop faces several phytosanitary problems, among which the effects caused by fungi infections, especially rust, are the major constraint in obtaining expected yields. It causes characteristic leaf lesions, fruit necrosis, and cankers on young stems and branches. If you know the name of the tree pest or disease affecting your trees, see the Forestry Commission guidance giving detailed information on specific tree pests or diseasesknown to be present in the UK. In addition to those, enhancing tolerance to biotic (pest and disease) and abiotic (drought, salinity, freezing, and heavy metals) stresses as another important genetic engineering strategy to facilitate the cultivation of nonedible oil plants under conditions unsuitable for food crops has been addressed. Griffon & Maubl causing root rot and collar rot disease of physic nut ( Jatropha curcas L.) in India, Control of Leaf-footed Bug Leptoglossus zonatus and Shield-backed Bug Pachycoris klugii with Entomopathogenic Fungi, Pests of economic importance on Jatropha curcas, a bio diesel plant in India, First Report of Cucumber mosaic virus on Jatropha curcas in India, Colonization of non-cassava plant species by cassava whiteflies (Bemisia tabaci) in Uganda, First record of Jatropha podagrica gummosis caused by Botryodiplodia theobromae in China, Natural infection of Acalypha hispida and Jatropha podagrica inflorescences by Amphobotrys ricini in Brazil, Lasiodiplodia theobromae is the causal agent of a damaging root and collar rot disease on the biofuel plant Jatropha curcas in Brazil, Sequestration of phorbolesters by the aposematically coloured bug Pachycoris klugii (Heteroptera: Scutelleridae) feeding on Jatropha curcas (Euphorbiaceae), Suitability of the predatory mites Iphiseiodes zuluagai and Euseius concordis in controlling Polyphagotarsonemus latus and Tetranychus bastosi on Jatropha curcas plants in Brazil, Metabolic and histopathological alterations of Jatropha mosaic begomovirus-infected Jatropha curcas L. by HR-MAS NMR spectroscopy and magnetic resonance imaging, A new strain of Indian cassava mosaic virus causes a mosaic disease in the biodiesel crop Jatropha curcas, Arthropod fauna associated with Jatropha curcas L.

Literature surveys revealed records of Jatropha mosaic virus on J. gossypiifolia in Puerto Rico (1) and on J. curcas in India (2). This has not been reported for J. curcas plants before. New and interesting collections of cercosporoid hyphomycetes from Brazil are reported in the present paper. Phytophagous mites, namely broad mite, Polyphagotarsonemus latus (Banks), and red spider mite, Tetranychus urticae Koch, infest Jatropha curcas. The total life cycle of broad mites lasted six days; females and males lived for nine and seven days, respectively, whereas that of the spider mite was six days. The objective is to outline how jatropha has performed in the region with a view to promote development work on the crop. To study the population dynamics of the pest in the Sissili Province of Burkina Faso, 12 sites were monitored weekly during a year and 31 sites were inspected for damage at the peak period of insect abundance. Versatile and showy, the clusters of tiny but vivid flowers stand out against deep green leaves and the small size makes it the perfect accent tree … It is now clear that the initial claims about jatropha have not been realized. Jatropha curcas L. is an important multipurpose and drought resistant large shrub or small tree. A few will rapidly kill trees and demand that you keep a watch for symptoms. assessment of J. curcas due to this pest has been conducted. The core coat protein (CP) sequences of ~575 bases were obtained from two isolates collected at Bangalore and Dharwad, South India. The findings are confirmed by means of numerical simulations. Spatial distribution studies in pest management identify the locations where pest attacks on crops are most severe, enabling us to understand and predict the movement of such pests. Using Ecological Niche Modelling and GIS post‐modelling analyses, we infer the current and future suitable territories for both these taxa, delineating areas where J. curcas cultivations may occur without suffering the presence of Aphthona, in the context of future climate and land use changing. 2014, Lama et al. Reduction of fruit, seed and seed kernel weight as well as seed length could be expressed as linear regressions of adult population densities. The disease is transmitted by the vector Bemisia tabaci in a non-persistent manner, but not through mechanical inoculation or seeds (Narayanaet al. The highest numbers of nov. was found on the green leaves ofJatropha gossypifolia in India. Jatropha curcas is an important commodity for farmers. n.; Aphthona dilutipes Jacoby, 1906=Aphthona damarorum Weise, 1914 syn. However, the role of alternative hosts in the ecology of cassava B. tabaci genotypes and their possible involvement in the epidemiology of cassava mosaic disease (CMD) in Uganda remain unknown. At high densities, however, it reduced the number of fruits maturing. However, based on the presence of B. tabaci 4th instar nymphs, the Ug1 genotypes (n = 13) colonized cassava and five other non-cassava plant species: Manihot glaziovii, Jatropha gossypifolia, Euphorbia heterophylla, Aspilia africana, and Abelmoschus esculentus, suggesting that cassava B. tabaci (Ug1 genotypes) are not restricted to cassava in Uganda. The Aphthona flea beetle (Coleoptera: Chrysomelidae) has been identified as the main pest of J. curcas in various regions of Africa [2] [3] [4]. (Deuteromycotina: Hyphomycetes) was assessed in the laboratory against adults of the leaf-footed bug Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae) and the shield-backed bug Pachycoris klugii Burmeister (Heteroptera: Scutelleridae), the two most frequent pest species in physic nut ( Jatropha curcas L., Euphorbiaceae) plantations in Nicaragua. Out of 61 primers, the amplification was obtained in 51 primers producing 384 bands. The result of this study also may be useful for an international audience to reflect on the appropriateness of promoting a new crop at the farmer level before realistically evaluating the economic viability of its cultivation. in mature conidia, is proposed for inclusion in the genusErysiphe. Jatropha is a genus of flowering plants in the spurge family, Euphorbiaceae.The name is derived from the Greek words ἰατρός (iatros), meaning "physician", and τροφή (trophe), meaning "nutrition", hence the common name physic nut.Another common name is nettlespurge. Bemisia tabaci adults and 4th instar nymphs were collected from cassava and 11 other cultivated and uncultivated species occurring adjacent to the sampled cassava fields. A complete list of diseases that exist in countries that cultivate Jatropha Curcas can be seen in an overview of pests and jatropha diseases written by Anitha and Varaprasad. You can also find out about those that pose a potential risk to the UK but are not present yet. and 5 replicates. The research was carried out at Cryogenic/UFCG, Sanity/UFPB and Cotton/Embrapa. CLV-C was also isolated from naturally infected Jatropha multifida (Euphorbiaceae) and Hewittia sublobata (Convolvulaceae). caged with a 4-year old The present compilation indicates that jatropha is susceptible to more than 35 fungal species, 4 viral and 4 bacterial pathogens, 6 nematodes and about 60 insect species. Mite spatial distribution models were isotropic. Growth and yield can be severely limited by poor management and reduced by pests. The effectiveness of M. anisopliae was further tested in field cages covering entire trees and containing a predetermined number of insects. Damage increased with the developmental stage of the larvae. The interspecific hybrids were successful only when the former was used as seed parent. Since they are living organisms, some biological insecticides can be produced cheaply and, if established in the environment, can provide sustained control with little or no reapplication. Jatropha are vulnerable to pests including aphids, mealy bugs, scale, and white fly. A sick tree can fall or lose large branches more easily, posing a risk to your family and home. All three species reduced overall yield. showed that the control (T0) and T1 (10.5% damage) showed Sustainable and optimized crop management may alleviate crop growth limitations and reductions, but not necessarily result in improved seed yields is a Heteropteran that feeds ), root rot disease (caused by Fusarium moniliforme) and damping off (caused by Phytophtora spp.) With a modest estimate of 6–8 years of concerted efforts, improved germplasm with desired attributes could be made available, and such improved germplasm can be used to replace the already established plantations with unproductive yields in a phased manner. Alterations in the anatomical structures, sap translocation and metabolic profiles in Jatropha curcas L. (Euphorbiaceae), infected with Jatropha mosaic virus (JMV) have been investigated using MRI and HR-MAS NMR spectroscopy. Jatropha curcas L. is an introduced plant species in India, and has gained importance as a biofuel plant. The results demonstrated the value of MRI and HR-MAS NMR spectroscopy in studying viral infection and metabolic shift in plants. The evaluation of the incidence of fungi was carried out in a stereoscopic microscope with observation of fungal structures, and values were expressed as percentages of seeds with fungus. Moreover, we find high economic losses (~ ‐50%) both in terms of carbon sequestration and in biodiesel production when J. curcas co‐occur with the Aphthona cookei species group. Vuil. The suitability of this host plant is described by the mortalities in the developmental stages from egg to adult, which are presented in a life table, and the durations of the different stages. The corrected mortalities ranged from 65% in P. klugii to 94% in L. zonatus. Although different entomopathogens and their products are currently used to control insect pests which offer certain advantages over conventional chemical insecticides, they also have certain disadvantages especially the lack of speed of kill in the case of insect viruses that has limited their application. In plantations, however serious problems of economic significance have been reported due to attack of various fungi, viruses, insects and other pests. It has become clear that jatropha may suffer attacks of pests and diseases, once cultivated in more intensive production systems (Meshram and Joshi, 1994; Nam Hei, 2008). A survey of the natural enemies of C. panaethiopica was carried out from 3rd June 2013 to Lychee Erinose Mite The Florida Department of Agriculture and Consumer Services has put an immediate quarantine in place for all of Lee County due to the presence of a major pest of lychee, Aceria litchii , known as lychee erinose mite. Keywords – Burkina Faso, Biofuel, Jatropha curcas, Calidea However, by itself, biological control often fails to control economic damage to the crop. Notwithstanding its high economic importance, few studies are available about its co‐occurrence with pests of the genus Aphthona in sub‐Saharan Africa, where these insects feed on J. curcas , leading to relevant economic losses. only as a supplement to current farming systems at least until reliable germplasm and agricultural practices provide consistent yields The viral stress also significantly increases the concentrations of alanine, arginine, glutamine, valine, GABA and choline as compared to healthy ones. Hence, fluorescent pseudomonads have lot of potential as biocontrol agent for the management of soilborne and foliar diseases of crop plants. Some of the characters such as stem type, branching habit, leaf size and shape of the hybrids resembled the female parent while others like leaf pigmentation, fruit and seed size, flower colour, resembled the male parent. This virus (CLV-C) did not infect Nicotiana clevelandii, a diagnostic host of the type strain (CLV-T); experimental host range was very restricted and CLV-C only infected N. benthamiana and N. rustica out of several solanaceous hosts readily infected by CLV-T. The two most frequent species found were Pachycoris klugii and Leptoglossus zonatus. Arch. Cultivated macadamia is a derivative of the subtropical species' Macadamia integrifoia and Macadamia tetraphylla and their hybrids. The 2-Dimensional and 3-Dimensional scaling by principal component analysis (PCA) grouped some hybrids with male parent, some with female parent while others in between both the parents. Sample locations were georeferenced. The parents and their 23 hybrid plants were subjected to random amplified polymorphic DNA (RAPD) analysis using 61 random decamer primers.
