Biocontrol 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...
متن کاملDevelopment 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 کاملEffect of Some Flavonoids on Survival and Development of Helicoverpa armigera (Hübner) and Spodoptera litura (Fab) (Lepidoptera: Noctuidae)
The aim of the study was to test the effect of three flavonoids on growth and survival of Helicoverpa armigera (Hüb) and Spodoptera litura (Fab.). A set of experiments were carried out with varying concentrations of three flavonoids namely chlorogenic acid, quercetin and rutin at 23±1oC on growth, development and mortality of larvae of pod borer Helicoverpa armigera and tobacco caterpillar Spod...
متن کاملIntraguild predation on Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae) by the generalist predator Geocoris ochropterus Fieber (Hemiptera: Geocoridae)
Intraguild predation (IGP) is common in food web when two natural enemies share the same resources and prey. It may affect the success or failure of a biological control attempt. The role of intraguild predation by Geocoris ochropterus Fieber (Heteroptera: Geocoridae) on Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae) developed on eggs of Helicoverpa armigera (Hubner) (Lepidoptera:...
متن کاملSpodoptera litura nuclear polyhedrosis virus (NPV-S) as a component in Integrated Pest Management (IPM) of Spodoptera litura (Fab.) on cabbage
Field tests were conducted to evaluate the effect of Spodoptera litura (Fab.) nuclear polyhedrosis virus (NPVS) alone and in combination with endosulfan and neemarin (neem seed kernel extract) against S. litura in cabbage. Treatment with NPV-S (500 LE/ha) + Endosulfan (625 ml/ha) was better in reducing the larval population and increasing yield than other treatments. However, considering cost b...
