Efficacy of Some Synthetic and Biopesticides Against Pod Borer, Helicoverpa armigera (Hubner) in Chickpea
Efficacy of some synthetic and biopesticides against pod borer, Helicoverpa armigera (Hubner) damage in chickpea was studied at the Regional Agricultural Research Station, Ishurdi, Pabna, Bangladesh during rabi cropping season of 2004-05. Synthetic and biopesticides reduced pod borer damage significantly. Significantly lowest pod damage was observed in cypermethrin (5.75%) and HNPV (5.86%) spra...
متن کاملProtease Inhibitors in Wild Relatives of Pigeonpea against the Cotton Bollworm/Legume Pod Borer, Helicoverpa armigera
Cotton bollworm/legume pod borer, Helicoverpa armigera is one of the most damaging pests worldwide. Because of the difficulties associated with chemical control of this pest, emphasis has been placed on developing transgenic plants with resistance to H. armigera. Since toxin genes from the bacterium, Bacillus thuringiensis (Bt) have been deployed on a large scale, there is need to scout for alt...

در این پایان نامه، در ابتدا برای مدول ها روی دامنه های پروفر شرایط معادل به دست آورده ایم و خواصی از ددکیند مدول ها روی دامنه های پروفر مشخص کرده ایم. در ادامه برای ددکیند مدول های با تولید متناهی روی حلقه های به طور صحیح بسته شرایط معادل به دست آورده ایم و ددکیند مدول های ضربی را مشخص کرده ایم. گزاره هایی در مورد بعد ددکیند مدول ها بیان کرده ایم. در پایان، قضایای lying over و going down را برا...
15 صفحه اولResponse of Cotton Bollworm Helicoverpa armigera (Hubner) (Lepidoptera:noctuidae) to Different Insecticides in Maharashtra, India
This study deals with Insecticide Resistance Management of cotton bollworm Helicoverpa armigera to five commonly used insecticides on cotton were carried out during 2008. In August, LD value for 50 chlorpyriphos varies from 0.046μg/larva in Parbhani district to 0.172 mg/larva during October in Aurangabad district. Resistance to chlorpyriphos was highest in Aurangabad district (3.65-8.25 fold) f...
متن کاملExploitation of wild relatives of pigeonpea and chickpea for resistance to Helicoverpa armigera
Wild relatives continue to evolve in nature, and live by a different rule than the crop plants – which is survival of the fittest. Wild species have evolved to survive droughts, floods, extremes of heat and cold, and have the capability to withstand damage by insect pests and diseases that cause heavy damage to cultivated species. Many improved cultivars of crops are vulnerable to insect pests ...
