Soybean plant architecture influences the capacity of Telenomus podisi to parasitize Euschistus heros eggs: implications for field releases

Pest Management Science, EarlyView.
Increasing soybean plant architectural complexity reduces the ability of Telenomus podisi to parasitize Euschistus heros eggs, highlighting the need to adjust parasitoid release rates in the field according to plant complexity (arrow direction and thickness correspond to the increasing strength of the variable) . Abstract BACKGROUND Plant architectural

Effect of Weeding Regime on the Weed Infestation and Crop Performance of Transplant Aman Rice

Journal of Science Foundation, 2013
An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymenshingh to study the effect of weeding regime on the weed infestation and crop performance on transplant aman rice. The treatments included 10 weeding regime - i) no weeding, ii) one hand weeding at 21 DAT, iii) two hand weeding at 21 and 42 DAT, iv)

Optimal irradiation parameters for the development of the sterile insect technique in the seedcorn maggot Delia platura (Diptera: Anthomyiidae)

Pest Management Science, EarlyView.
X‐ray irradiation of Delia platura pupae showed that 20 Gy induces high sterility while maintaining male quality and competitiveness, establishing optimal parameters for sterile insect technique implementation in North America. Abstract BACKGROUND The seedcorn maggot, Delia platura Meigen (Diptera: Anthomyiidae), is a sporadic but economically ...

Methomyl resistance in Dalbulus maidis (Hemiptera: Cicadellidae): selection, inheritance and multiple‐resistance

Pest Management Science, EarlyView.
The inheritance of methomyl resistance in Dalbulus maidis is autosomal, incompletely dominant and polygenic. No cross‐resistance was found between methomyl and chlorfenapyr, cyantraniliprole and isocycloseram. Abstract BACKGROUND Acetylcholinesterase (AChE) inhibitor insecticides have been important tools for the management of Dalbulus maidis in Brazil;

Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

Pest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype
