the development times and the survival rates of different stages of habrobracon hebetor say reared on the last instar larvae of galleria mellonella (l.) were compared at ten different constant temperatures (16 - 38 âºc). the development time of immature stages of the parasitoid, h. hebetor, decreased as the temperature increased in the range of 16 to 38 âºc. however, no larvae could survive and...

insect growth regulators and spinosyns which are physiologically and ecologically selective, respectively, have been investigated as replacements or complements to non-selective conventional insecticides. the effects of diflubenzuron, hexaflumuron, profenofos, spinosad and thiodicarb were assessed on the 1st instars of cotton bollworm, helicoverpa armigera (hã¼bner) using dietary and leaf disc ...

The survival of stored product insect natural enemies in wheat treated with spinosad was investigated in laboratory and pilot scale experiments. The predator Xylocoris flavipes (Reuter), the warehouse pirate bug, and the parasitoids Habrobracon hebetor (Say), Theocolax elegans (Westwood), and Anisopteromalus calandrae (Howard) were exposed to wheat treated with aliquots of water or spinosad at ...

sublethal effects of two juvenile hormone analogue, flufenoxuron and lufenuron, were evaluated on larval, pupal and adult stages of habrobracon hebetor say under laboratory conditions. dose-response bioassays were carried out on the insect’s immature and adult stages through dipping and contact residue methods. in the sublethal effect tests, field rates (500 ppm) of the two insecticides were em...
