“…The present results revealed that cowpea plants were infested with A. gossypii and A. craccivora these pests were recorded on cowpea plants by Mali and Kulthe (1980) and Hassan (2009). However, intercropping of cotton with cowpea significantly influenced the spread of A. gossypii, E. dicipiens and B. tabaci.…”

This study was conducted to evaluate the effect of intercropping and potassium fertilization for maize with cowpea plants on the population density levels of some piercing-sucking insects at Diarb Negm distract in Sharkia Governorate during 2009 and 2010 seasons. The obtained results showed that intercropping system (3:3) maize with cowpea decreased Rhopalosiphum maidis (Fitch), Rhopalosiphum padi(L .) , Aphis gossypii (Glover), Empoasca decedens (Paoli), Empoasca decipiens(Paoli) , Cicadulina chinai (Ghauri) and whitefly Bemisia tabaci (Genn.). Whereas, increased average numbers of planthopper Sogatella vibix (Haupt) and Sogatella furcifera (Horv.) in both seasons. The results indicate that increased of yield in the solid system but insignificantly with intercropping system (3:3). Data presented clearly that rate of 100 kg of potassium fertilization / fed. gave increased of yield maize with cowpea plants and decreased infestation of sap-sucking insects in both seasons. Lysiphlebus fabarum (Marshall) was the singe primary parasitoid species emerged from Aphis craccivora (Koch.) mummies Also, Diaeretiella rapae (M' Intosh) was the primary parasitoid emerged from R. maidis mummies and Praon sp. was the primary parasitoid emerged from R. padi mummies. The mean percentage of parasitoid were 5.52 ± 2.02 and 4.33 ± 1.58 in (L. fabarum), 1.21 ± 0.43 and 1.71 ± 0.46 (D. rapae) and it were 1.38 ± 0.53 and 1.11 ± 0.35 (Praon sp.) in both seasons respectively. Five predators were associated with these insects on cowpea crop. These predators were Coccinella undecimpunctata (L.), Cydonia vicina isis, Cy. vicina nilotica, Metasyrphus corolla (F.) and Chrysoperla carnae (Steph). Meanwhile three predators were associated with these insects on maize crop. These predators were C. undecimpunctata, M. corolla (F.) and C. carnae.

“…It was found that only symptomatic plants showed presence of virus serologically. The CABMV has been reported in many countries in different continents including Asia, Africa, Europe, North and South America and Australia (Mali and Kulthe, 1980;Huguenot et al, 1993;Bashir and Hampton, 1996;Pio-Ribeiro et al, 2000;Behncken and Maleevsky, 1977). Since, biological properties of CABMV may differ among isolates worldwide (Bashir et al, 2002); it becomes imperative to identify resistance sources against the local prevalent viral strains.…”

Cowpea (Vigna unguiculata (L.) Walp), an important protein rich arid legume crop is susceptible to number of fungal, bacterial and viral diseases that severely limit the productivity. A set of 92 diverse cowpea genotypes including varieties, mutants, advanced breeding lines, exotic and indigenous collections were serologically screened for resistance against Cowpea Aphid Borne Mosaic (CABM) virus using DAS-ELISA. The genotypes grown in triplicate in a randomized block design at Trombay were mechanically inoculated with CABM virus and the resistance or susceptible reactions of each of the genotypes were recorded visually as well as serologically. Based on the extent of symptoms and serological reactions, the cowpea genotypes were classified as: highly resistant, plants without symptoms and negative for serology; resistant, plants with mild mosaic (<25%) and positive for serology; susceptible, plants with mosaic (26-75%) and positive for serology and highly susceptible, plants with severe mosaic (>75%) and other systemic symptoms and positive for serology. The study resulted in the identification of 13 highly resistant, 24 resistant, 50 susceptible and 5 highly susceptible genotypes. The chlorophyll index of susceptible genotypes as measured by SPAD chlorophyll meter was almost half that of resistant genotypes. The highly resistant genotypes against CABM virus identified in the present study after due confirmation would be incorporated in the breeding programme to develop resistance in elite genetic backgrounds.
