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...

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...

Chemical Ecology of the Colorado Potato Beetle,

The Colorado potato beetle (CPB) has been a major insect pest to potato farming for over 150 years and various control methods have been established to reduce its impact on potato fields. Crop rotation and pesticide use are currently the most widely used approaches, although alternative methods are being developed. Here we review the role of various volatile and nonvolatile chemicals involved i...

Field Evaluation of Natural, Engineered, and Combined Resistance Mechanisms in Potato for Control of Colorado Potato Beetle

The colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae), is the leading insect pest of potato (Solanum tuberosum L.) in northern latitudes. Host plant resistance has the potential use in an integrated pest management program for control of colorado potato beetle. During the 1998 and 1999 seasons, field studies were conducted to compare natural (leptine glycoalkaloi...
