Development of endosulfan tolerant strain of an egg parasitoid Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae).
A strain of T. chilonis, an egg parasitoid of lepidopteran pests tolerant to the most commonly used cyclodiene insecticide--endosulfan was developed in the laboratory. Tolerance to endosulfan was induced by exposing adult parasitoids sequentially from a sub-lethal concentration (0.004%) to the field recommended concentration (0.09%). The strain acquired tolerance to the insecticide after 341 ge...
متن کاملBiocontrol efficacy and viability of Trichogramma chilonis on Corcyra cephalonica and Spodoptera litura under laboratory conditions
Trichogramma, an egg parasitoid can be used in controlling many lepidopteran pests. Therefore, it is necessary to demonstrate the capacity of these natural enemies in controlling the pest population so as to use them in biological control programs against the pest. Such an attempt was made in this particular study, where the parasitization rate of Trichogramma chilonis was tested on the eggs of...

Emergence and survival of adults for 24 hwas compared forTrichogramma chilonis Ishii reared on eggs of Corcyra cephalonica (Stainton) adults whose larval growth and development had beenmonitored on broken grains of four different cereals: Þngermillet (Eleusine coracanaL.Gaertn), softwhitewheat (TriticumaestivumL), short-grainedwhite rice (Oryza sativaL.), anddurra sorghum (Sorghum bicolor L.

متن کاملEffect of fumigation and juvenile hormone on oxygen consumption of the larvae of Corcyra cephalonica (Stainton).
Reduced effect of JH-I, JH-II and JH-III on oxygen consumption of II-V instars and increased effect on the oxygen consumption of VI instar larvae suggested that control of corcyra with juvenile hormones could be brought about only when applied to just emerged VI instar larvae. Similarly fumigation of juvenile hormone treated larvae could prove beneficial only at VI instar stage. The possibility...
