Evaluation of Some Insecticides and Biopesticides for Management of Barley Aphid (Rhopalosiphum maidis)
Barley, Hordeum vulgare Linn. (family: Gramineae) is an important cereal crop of Rabi season grown in India. The chapattis made up of barley flour are very palatable and can be easily digested even by the persons suffering from stomach ailments. Besides an ideal feed and fodder for livestock, the crop has acquired the status of an industrial crop in malting and brewing. This crop could perform ...
متن کاملAdditive effects of two quantitative trait loci that confer Rhopalosiphum maidis (corn leaf aphid) resistance in maize inbred line Mo17
Plants show considerable within-species variation in their resistance to insect herbivores. In the case of Zea mays (cultivated maize), Rhopalosiphum maidis (corn leaf aphids) produce approximately twenty times more progeny on inbred line B73 than on inbred line Mo17. Genetic mapping of this difference in maize aphid resistance identified quantitative trait loci (QTL) on chromosomes 4 and 6, wi...
متن کاملمدل نمونه‌برداری دنباله‌ای برای پایش شته برگ ذرت Rhopalosiphum maidis (Fitch) در مزارع سورگوم جارویی منطقه میانه
این پژوهش به منظور تعیین نوع توزیع فضایی و ارایه مدل نمونه برداری دنباله ای برای تخمین دقیق تراکم جمعیت شته برگ ذرت (Fitch) Rhopalosiphum maidis در مزارع سورگوم جارویی منطقه میانه انجام شد. برای نمونه برداری از جمعیت شته، هر سه روز یکبار تعداد 50 ساقه سورگوم جارویی مورد بازدید قرار گرفت و میانگین و واریانس جمعیت در هر تاریخ نمونه برداری برای تخمین پارامترهای توزیع فضایی مورد است...
متن کاملEfficacy of different insecticides against aphid on brassica juncea
A field experiment was conducted to find out and compare the efficacy of Pyriproxyfen, Nitenpyram, Carbosulfan and Chlorpyrifos against aphid on Brassica juncea variety (Bahawalpur Raya) during Rabi 2016-17 at Regional Agricultural Research Institute, Bahawalpur, Pakistan. After 72 hours of treatment carbosulfan, nitenpyram and pyriproxyfen showed statistically similar results. Aphid population...
متن کاملHigh Susceptibility of Bt Maize to Aphids Enhances the Performance of Parasitoids of Lepidopteran Pests
Concerns about possible undesired environmental effects of transgenic crops have prompted numerous evaluations of such crops. So-called Bt crops receive particular attention because they carry bacteria-derived genes coding for insecticidal proteins that might negatively affect non-target arthropods. Here we show a remarkable positive effect of Bt maize on the performance of the corn leaf aphid ...
