اثر سم Bacillus thuringiensis Berliner روی برخی ویژگی‌های زیستی زنبور پارازیتوئید Habrobracon hebetor (Say) (Hymenoptera: Braconidae)
چکیده به منظور بررسی طول عمر، ترجیح میزبانی، طول دورهی مراحل زیستی و تعداد نتاج تولیدی زنبور Habrobracon hebetor روی لارو میزبان Ephestia kuehniella تیمار شده با دزهای کشنده و زیر کشنده باکتری Bt آزمایشی در قالب طرح کاملا تصادفی در شرایط آزمایشگاه اجرا شد. نتایج نشان داد تعداد تخم زنبور از 9/3 عدد در تیمار شاهد به 4/1 و 7/2 عدد به ترتیب در دزهای کشنده و زیر کشنده کاهش یافت. با کاهش تعداد نتاج ...
متن کاملBiological, nutritional, and histochemical basis for improving an artificial diet for Bracon hebetor Say (Hymenoptera: Braconidae).
The biology of Bracon hebetor Say (Hymenoptera: Braconidae) reared on fifth instars of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) (natural diet) and in vitro (artificial diet) was evaluated. Data on the number of instars, development time and food intake were collected, and histochemical tests were conducted to detect proteins and lipids in the parasitoid's digestive tract. The data ...

DemographyofHabrobraconhebetor(Say)(Hymenoptera:Braconidae)on twopyralid host species [Galleria mellonella (L.) and Ephestia kuehniella Zeller] (Lepidoptera: Pyralidae) was studied at 28 C in the laboratory. Data were analyzed based on an age-stage, two-sex life table, to take both sexes and variable development into consideration. The intrinsic rate of increase (r), Þnite rate of increase ( ),...
متن کاملInsecticidal Activity of the Essential Oils from Different Plants Against Three Stored-Product Insects
This study was conducted to determine the insecticidal activity of essential oils from oregano, Origanum onites L. (Lamiales: Lamiaceae), savory, Satureja thymbra L. (Lamiales: Lamiaceae), and myrtle, Myrtus communis L. (Rosales: Myrtaceae) against three stored-product insects. Essential oils from three species of plants were obtained by Clevenger-type water distillation. The major compounds in...
متن کاملAlterations in esterases are associated with malathion resistance in Habrobracon hebetor (Hymenoptera: Braconidae).
Biochemical mechanisms of malathion resistance were investigated in a malathion-resistant strain of the parasitoid Habrobracon hebetor Say collected from a farm storage in Kansas. General esterase activities were significantly lower in the resistant strain compared with those in a susceptible strain. However, no significant differences were found in activities of malathion specific carboxyleste...
