The IPM Innovation Lab has developed and tested robust IPM IPM PACKAGES FOR HEALTH CROP IPM PACKAGES packages, holistic suites of IPM recommendations and practices for the production of vegetables and other crops. Farmers who use IPM packages in planting and produc- tion see enhanced profitability in their crops. The recommended practices in IPM packages cover economically significant pest spe- cies over a wide range of cropping systems across the tropical world, with resulting benefits to human health and the environment.

  • Dwarf-Cashew Resistance to Whitefly (Aleurodicus Cocois) Linked To
    Research Article Received: 12 February 2019 Revised: 14 June 2019 Accepted article published: 25 June 2019 Published online in Wiley Online Library: 27 July 2019 (wileyonlinelibrary.com) DOI 10.1002/ps.5531 Dwarf-cashew resistance to whitefly (Aleurodicus cocois) linked to morphological and histochemical characteristics of leaves Elaine SS Goiana,a Nivia S Dias-Pini,a* Celli R Muniz,a Arlete A Soares,b James C Alves,b Francisco C Vidal-Netoa and Cherre S Bezerra Da Silvac Abstract BACKGROUND: The cashew whitefly (CW), Aleurodicus cocois, is an important pest of cashew in Brazil. The use of resistant plants may be an effective strategy for the control of this pest. In a preliminary assay, we found that dwarf-cashew clones show different levels of resistance to CW. Here, we hypothesized that such resistance is associated with morphological characteristics of cashew leaves and their content of phenolic compounds. RESULTS: We determined (i) the attractiveness and suitability for oviposition of five dwarf-cashew clones towards CW, (ii) the leaf morphology and chemistry of those clones, and (iii) the relationship between leaf characteristics and resistance to CW. In greenhouse multiple-choice assays, PRO143/7 and CCP76 showed, respectively, the lowest and highest counts of both CW adults and eggs. Scanning electron microscopy (SEM) analysis revealed that PRO143/7 and EMBRAPA51 have, respectively, the highest and lowest numbers of leaf glandular trichomes. We found a negative correlation between number of trichomes in the abaxial surface of cashew leaves and CW oviposition. In addition, confocal microscopy analysis and histochemical tests with ferrous sulfate indicated a higher accumulation of phenolic compounds in the resistant clone PRO143/7 relative to the other clones.

E-mail: [email protected]. Accepted 26 November, 2009 The developmental biology of Aleurodicus dispersus Russel., have been investigated. It was found to have a cumulative developmental period of (23 - 41) days. The mean numbers of egg developing to adult have been found to be 138.1 per thousand eggs. The spread of the insect have been found to be connected to human traffics. The oviposition and feeding occurs simultaneously and occur more on their abaxial surface of host leaves. Rainfall and temperature play a prominent role on the abundance and seasonal fluctuation of the insect and infact, regulating their population. Presently, A. dispersus is found on arable as well as ornamental plants but rarely on gramminae.

    Giant whiteflies (Sternorrhyncha, Aleyrodidae): a discussion of their taxonomic and evolutionary significance, with the description of a new species of Udamoselis Enderlein from Ecuador Jon H. Martin Three adult male whitefly specimens from Ecuador are described as Udamoselis estrellamarinae sp. n. This genus and its subfamily are reappraised on adult characters, including wing venation, paronychium structure, and distribution of abdominal wax glands. In the absence of associated puparia nomenclatural caution is preferred, but the subfamilies Udamoselinae and Aleurodicinae are likely to be synonymous. Wing venation of other very large whiteflies is illustrated, and is discussed in comparison with fossil taxa. Speculation is made on the possible biology of such giant whitefly species. Jon H.

This species was first observed in south Florida in 2009, which was the first report of its occurrence in the United States. As of July 2013, it has been found in 17 counties in south and central Florida. This whitefly has been reported on more than 60 plant species, which include gumbo limbo (Bursera simaruba), coconut (Cocos nucifera), black olive (Bucida buceras), avocado (Persea americana), Calophyllum spp., and giant white bird Figure 1.

    Basic Arthropod Taxonomy Arthropods include the insects, spiders, mites, ticks, ostracods, copepods, scorpions, centipedes, shrimps, and crayfishes. Of these, insects make up > 50% of all the nominal species of organisms in the world. Insects and its allies or relatives whether pests or beneficials are part of rice ecosystems. Basic arthropod identification is important in ecological research to understand interactions, which are vital for developing better pest management tools and strategies. This manual will focus on: • Identification of different arthropod groups. • Identification of major diagnostic features of the most common and important arthropod orders, families and species especially insects and spiders in the rice agricultural landscape using taxonomic keys. • Handling and preserving arthropods for identification.
