Effects of Differential Host Plant Consumption by Spodoptera exigua (Lepidoptera: Noctuidae) on Bacillus thuringiensis Efficacy
Environ. Entomol. 22(2): 432-437 (1993) ABSTRACT Bacillus thuringiensis Berliner toxicity is a dose-dependent phenomenon, and the dose acquired by an individual is directly related to the quantity of treated food consumed. A bioassay was conducted using two Apium graveolens var. rapaceum (L.) cultivars to determine if the B. thuringiensis dose acquired by Spodoptera exigua (Hiibner) (Lepidopter...
متن کاملDesign of a Bacillus thuringiensis-based formulation that increases feeding preference on Spodoptera exigua (Lepidoptera: Noctuidae) larvae.
A Bacillus thuringiensis (Bt)-based formulation intended to increase feeding response in Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) was developed. Eight matrices were prepared from natural ingredients and confronted with fresh maize leaves to select one highly palatable to larvae. The selected matrix was combined with Bt HD-125 strain at three different concentrations (30, 70, and 100 ...
متن کاملSwitching among natal and auxiliary hosts increases vulnerability of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) to insecticides
The role of insecticidal application and host plant resistance in managing Spodoptera exigua has been well documented, but the effect of different host plants, on which the pest cycles its population in the field, has seldom been investigated. Therefore, we have studied the vulnerability of S. exigua against commonly used insecticides (cypermethrin, chlorpyrifos, lufenuron, and emamectin benzoa...
متن کاملResponses of the cutworm Spodoptera litura (Lepidoptera: Noctuidae) to two Bt corn hybrids expressing Cry1Ab
To examine the responses of the secondary lepidopteran pest Spodoptera litura to two Bacillus thuringiensis (Bt) corn hybrids [5422Bt1 (Event Bt11), 5422CBCL (MON810)] expressing Cry1Ab, larval bioassays with Cry1Ab toxin, corn leaves or kernels and bagging on corn plants were conducted. The results showed that larvae displayed a similar performance when fed kernels, but not leaves of 5422Bt1, ...
متن کاملاثر متوکسی‌فنوزاید، لوفنوران و فلوفنوکسوران روی برگ‌خوار چغندرقند (Spodoptera exigua (Lepidoptera: Noctuidae در شرایط آزمایشگاهی
برگ خوار چغندرقند Spodoptera exigua (Hübner) از آفات مهم گیاهان زراعی بوده و دامنه‌ی میزبانی وسیعی دارد. استفاده از حشره‌کش‌های امن تر با نحوه ی اثر متفاوت و احتمال کمتر بروز مقاومت مثل تنظیم کننده های رشد حشرات در برنامه‌های مدیریت این آفت از جایگاه ویژه‌ای برخوردار است. در این پژوهش اثر سه تنظیم‌کننده‌ی رشد حشرات به نام‌های متوکسی‌فنوزاید، لوفنوران و فلوفنوکسوران روی لاروهای سن اول برگ‌خوار چ...
