The presence of chitin in midgut structures of Callosobruchus maculatus larvae was shown by chemical and immunocytochemical methods. Detection by Western blotting of cowpea (Vigna unguiculata) seed vicilins (7S storage proteins) bound to these structures suggested that C. maculatus-susceptible vicilins presented less staining when compared to C. maculatus-resistant vicilins. Storage proteins pr...

The repellent activity of monoterpenoids viz. eugenol, zimtaldehyde and neem oil against pulse beetle, Callosobruchus maculatus (F.) was investigated. Responses varied significantly with compound, dose and exposure time. The tested components showed highest level of repellency against C. maculatus at a dose of 1 μl. Over 80%, Class V, repellency was achieved after 5 to 60 min. treatment with th...

Abstract The chickpea, Cicer arietinum L. (Fabales: Fabaceae), seeds are vulnerable, both in the field and in storage, to attack by seed-beetles. Beetles of the genus Callosobruchus are major storage pests of chickpea crops and cause considerable economic losses. In the present study, a total of 11 chickpea genotypes including five 'kabuli' (Mexican white, Diyar, CA 2969, ILC 8617 and ACC 245) ...

Effect of solvent residues of Vitex negundo L. and Cassia fistula L. leaves (0.5 and 1%) was studied on egg laying and adult emergence of Callosobruchus maculatus Fab. and on percentage of larval parasitism by Dinarmus vagabundus (Timberlake). Cowpea seeds treated with methanol and aqueous extract of Vitex, at these concentrations (0.5 and 1%), significantly reduced the number of eggs and emerg...

It is recorded the occurrence of Pyemotes tritici (Lagréze-Fossat & Montagné) on Cathartus quadricollis (Guérin-Méneville) and Callosobruchus maculatus (Fabricius), reducing insect’s populations in laboratory conditions. This mite was observed feeding on larvae and pupae of C. quadricollis, and adults of C. maculatus. The mite toxin quickly paralyzed larvae and adults attacked. The mite P. trit...

سوسک چهار ­نقطه­ ای حبوبات callosobruchus maculatus pic. (col., bruchidae)، از جمله آفات انباری مهمی است که سالانه خسارات کمی و کیفی زیادی به حبوبات در شرایط مزرعه و انبار وارد می ­سازد. در این تحقیق جهت بررسی اثر نور و دما روی رشد و نمو سوسک چهار نقطه­ ای حبوبات و یافتن دما و رژیم مناسب نوری به منظور نگهداری حبوبات در محیط انبار، از 3 دمای 20، 25 و 30 درجه سلسیوس و 2 رژیم نوری تاریکی مطلق و رو...

The cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Bruchidae), is an important pest of stored cowpea, Vigna ungiculata (L.) Walpers (Fabales: Fabaceae), with ample distribution in tropical and subtropical regions. Many plant essential oils have a broad-spectrum activity against pest insects, and these oils traditionally have been used in the protection of stored products. In this study...
