Seeds of various wild and cultivated pulses express varied degrees of resistance to damage by Callosobruchus maculatus, a major pest of stored pulses. Seeds were analysed for trypsin/chymotrypsin inhibitors (qualitatively and quantitatively) and protein pro®les (SDS-polyacrylamide gel electrophoresis) to study the chemical basis of resistance to bruchid infestation. Seeds of the wild pulses Dun...
سوسک چهار نقطه ای حبوبات (callosobruchus maculatus f.) مهمترین آفات انباری است که به انواع حبوبات شامل لوبیا ، نخود، ماش، عدس و غیره خسارت کمی و کیفی می رساند. تاثیر نوع میزبان روی برخی از ویژگی های زیستی این آفت شامل میزان تخم ریزی، درصد خروج حشرات بالغ، وزن حشرات بالغ خارج شده و طول دوره زندگی آن مورد بررسی قرار گرفت. آزمایش در قالب طرح کاملاً تصادفی با پنج تکرار در شرایط دمایی 1 ± 30 درجه س...
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...
Over 90% of the insect damage to cowpea seeds is caused by Callosobruchus maculatus. Although, many chemicals have proven their efficacy against C. maculatus, they adversely affect natural environment. Death non-targeted species which are enemies other pests and development resistance possible. Therefore, current study was conducted determine effect plant leaves Murraya koenigii (“Karapincha”),...
Postharvest insect pests threaten the nutritional and financial security of smallholder farmers in the developing world. Hermetic storage, a technology that protects grain against insects by blocking their supply of oxygen, alleviates the problem of insect-caused losses. PICS (Purdue Improved Crop Storage) bags represent one hermetic technology that improves food availability and incomes of far...
The maximum present of protein was recorded PUSA-256(24.67) at par by KGD – 1168, Pant G-186, Kw-168 having 24.32, 23.42, and 23.67 percent respectively. infected grain Callosobruchus maculatus minimum KPG-59 (21.06) PUSA 256 (25.07) percent. fresh found PUSA-256 (24.67) KPG-59(21.06).
Pulse beetle (Callosobruchus maculatus) is a common weevil that responsible for up to 24% of stored pulse losses. Using black gram grain storage, the efficiency carbon dioxide gas against all life stages Callosobruchus maculatus insects was tested at various concentrations and exposure times. The trials were carried out in pilot bins with capacity 25 kg. At CO2 concentration 50%, complete morta...
Genetic admixture propels invasions of Callosobruchus maculatus across experimental landscapes. In Focus: Wagner, N.K., Ochocki, B.M., Crawford, K.M., Compagnoni, A. & Miller, T.E.X. (2017) Genetic mixture of multiple source populations accelerates invasive range expansion. Journal of Animal Ecology, 86, 21-34. In this issue of Journal of Animal Ecology, Wagner et al. (2017) demonstrate that ge...
در این تحقیق ویژگی های زیستی و رفتاری زنبور پارازیتوئید ( anisopteromalus calandrae (howard) (hym.: pteromalidae روی لارو سن چهار سوسک( callosobruchus maculatus (f.) (col. : bruchidae در شرایط آزمایشگاهی با دمای 1 ± 25 درجه سانتی گراد ، دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی و رطوبت نسبی 5 ± 20 درصد بررسی گردید. طول دوره پیش از ظهور حشرات کامل زنبور روی میزبان 038/0 ± 82/19 روز تعیین شد. دور...
Nearly all mungbean cultivars are completely susceptible to seed bruchids (Callosobruchus chinensis and Callosobruchus maculatus). Breeding bruchid-resistant mungbean is a major goal in mungbean breeding programs. Recently, we demonstrated in mungbean (Vigna radiata) accession V2802 that VrPGIP2, which encodes a polygalacturonase inhibiting protein (PGIP), is the Br locus responsible for resist...
