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...

Glycoalkaloid 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...

Field efficacy of novaluron for control of Colorado potato beetle (Coleoptera: Chrysomelidae) on potato

Field trials were conducted in 2003 and 2004 to assess the effectiveness of novaluron (Rimon 10EC), a benzoylphenyl urea chitin synthesis inhibitor, for Colorado potato beetle, Leptinotarsa decemlineata (Say), management on potato. Foliar applications of novaluron did not significantly reduce numbers of L. decemlineata adults, egg masses, or first instar larvae, but second–fourth instars were g...

Habitat manipulation in potato affects Colorado potato beetle dispersal

The Colorado potato beetle [Leptinotarsa decemlineata (Say); Coleoptera: Chrysomelidae] is a significant pest of potatoes in North America and Eurasia and can cause severe defoliation and yield loss (Ferro 1985; Weber and Ferro 1994b). Managing the Colorado potato beetle with intensive pesticide applications has led to resistant populations (Forgash 1985; Ioannidis et al. 1991; Stewart et al. 1...
