Evidence of Cuticle Chemicals of Heortia vitessoides (Lepidoptera: Crambidae) Larvae Influencing the Aggregation Behavior of Conspecific Larvae

Insects
Heortia vitessoides (Lepidoptera: Crambidae) is a severe pest of Aquilaria plants, which produce high-priced agarwood. The larval stage of this pest is gregarious, usually forming large aggregates during young instars and becoming solitary during the ...

Cumulative effect of HaNPV against Helicoverpa armigera infesting Chickpea

Environment Conservation Journal, 2016
The instar-wise larval mortality in H. armigera due to HaNPV @ 0.500 ml/l showed a consistent decrease in all the five instars and cent per cent larval mortality was recorded in the first instar larvae.

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

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

Prey preference of Eupeodes corollae (Dip.: Syrphidae) on different nymphal instars of Brevicoryne brassicae (Hem.: Aphididae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2012
The prey stage preferences of the second and third instar larvae of syrphid fly species Eupeodes corollae (Fabricius) on different nymphal instars of Brevicoryne brassicae (L.) were studied in no-choice and choice conditions (25 ± 2°C, 65 ± 5% R.H ...
