Nutritional indices of the Colorado potato beetle, Leptinotarsa decemlineata (Col.: Chrysomelidae) on six potato cultivars
سوسک کلرادوی سیب زمینی، Leptinotarsa decemlineata (Say)، یکی از آفات مهم سیب زمینی در ایران و جهان است. شاخص‌های تغذیه‌ای لاروهای سن آخر این آفت روی برگ ارقام مختلف سیب زمینی (خاوران، ساوالان، لوتا، سانتا، سانته و آئولا) تحت شرایط آزمایشگاهی (دمای 1 ± 25 درجه سلسیوس، رطوبت نسبی 5 ± 65 در‌صد و دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی) بررسی شد. لاروهای پرورش‌یافته روی رقم سانته کم‌ترین کارا...
متن کاملCombining Engineered (Bt-cry3A) and Natural Resistance Mechanisms in Potato for Control of Colorado Potato Beetle
The Colorado potato beetle [Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)] is a destructive pest of the cultivated potato (Solanum tuberosum L.) in northern latitudes. Combining resistance mechanisms of leptine glycoalkaloids and glandular trichomes with the synthetic Bacillus thuringiensis Berliner (Bt) cry3A gene in potato may be an effective strategy for controlling the Colorado ...
متن کاملinteractions of transgenic-bt potato resistance to colorado potato beetle with the fitness and behavior of the potato aphid macrosiphum euphorbiae
the performance and flight behavior of the potato aphid macrosiphum euphorbiae was studied on the 'superior-bt' line transgenic for the cryiiia toxin of bacillus thuringien-sis (bt), resistant to the colorado potato beetle; and non transformed 'superior' line which served as control. mortality of the treated aphids was negligible and potato lines did not affect the development time of m. euphor...
متن کاملGlycoalkaloid responses of potato to Colorado potato beetle defoliation.
Two experiments were conducted to measure the glycoalkaloid concentrations of potato tubers in response to Colorado potato beetle and manual defoliation. For plants defoliated by Colorado potato beetles, there was a significantly greater production of glycoalkaloids than in control plants and manually defoliated plants for both skin and inner tissue of tubers in experiment 1. In experiment 1, t...
متن کاملResistance potential of colorado potato beetle (Coleoptera: Chrysomelidae) to novaluron.
Novaluron (Rimon 10 EC), a novel insect growth regulator, could play an important role in future management programs for Colorado potato beetle, Leptinotarsa decemlineata (Say). Studies were conducted to determine the potential of Colorado potato beetle to develop resistance to novaluron before its widespread use in Colorado potato beetle management. Second instars of an imidacloprid-resistant ...
