Side-Effect of Certain Herbicides on Egg Parasitoid Trichogramma evanescens (West.) (Hymenoptera: Trichogrammatidae)
Three laboratory experiments were conducted to evaluate the side-effects of four common herbicides used to control weeds associated with local crops on egg of the parasitoid Trichogramma evanescens. These herbicides are Glyphosate 48%SL, Bromoxynil 24%EC, Thiobencarb 50% and Clodinafop-propargyl 15%WP. The biological aspects such% parasitism, % adult emergence, sex ratio, developmental period a...
متن کاملAssessment of Trichogramma japonicum and T. chilonis as Potential Biological Control Agents of Yellow Stem Borer in Rice
Two species of Trichogramma wasps were assessed for their effectiveness against yellow stem borer Scirpophaga incertulas. A laboratory cage test with T. japonicum and T. chilonis showed that both species parasitized yellow stem borer egg masses at 60.0% ± 9.13% and 40.7% ± 7.11%, respectively, with egg parasitism rates of 15.8% ± 22.2% for T. japonicum and 2.8% ± 5.0% for T. chilonis. Once the ...
متن کاملFactors Influencing the Adoption of Biological Control of Rice stem borer (Chilo Suppressalis) in Talesh Region, Iran
Among the agricultural crops, rice has had the largest share in pesticide use. Most of the croplosses are caused by the attack of Chilo suppressalis. The purpose of this study was toexamine effective factors on adoption of biological control by farmers in Talesh region ofIran. A survey study was conducted using a stratified random sampling to collect data fromfarmers in the selected rural areas...
متن کاملThe effect of development time on the fitness of female Trichogramma evanescens
Trichogramma are facultative gregarious egg parasitoids that attack a wide range of lepidopterous eggs. Because hosts in which parasitoids develop vary in terms of available food, the progeny produced by parasitoid females vary in size and fitness. While one might expect that the developmental rate and emergence rhythm should be similar for all individuals reared under the same environmental co...
متن کاملAssessment of Yield Loss in Rice due to Yellow Stem Borer, Scirpophaga incertulas, Using Simulation Models
The yield loss simulation (YLS) and the MACROS LIQ.CSM models were used to simulate the effect of stem borer damage at a detillering rate of 5, 15, 30, 60% at vegetative, panicle initiation and grain filing stages, on yield of rice cultivar?s Ratna. This stem borer damage during vegetative and panicle initiation stages was not simulated appropriately by both the models. Relatively MACROS simul...
