SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Size-induced reproductive constraints in an egg parasitoid

Journal of Insect Physiology, 2012
The size of adult parasitoids is influenced by the quantity and quality of resources available during immature development. Gregarious development of endoparasitoids results in scramble competition where the resources are shared among individuals developing into the same host.

Temperature-dependent development of Habrobracon hebetor (Hym.: Braconidae) reared on larvae of Galleria mellonella (Lep.: Pyralidae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2008
The development times and the survival rates of different stages of Habrobracon hebetor Say reared on the last instar larvae of Galleria mellonella (L.) were compared at ten different constant temperatures (16 - 38 ºC).

Comparative study on the egg parasitoids of Erthesina fullo (Thunberg, 1783) (Hemiptera, Pentatomidae) in its native and invaded ranges [PDF]

NeoBiota
Erthesina fullo (Thunberg, 1783) (Hemiptera, Pentatomidae) is an emerging invasive pest outside its native Asian range, yet little is known about its egg parasitoids. Egg parasitoid assemblages were surveyed from field-collected egg masses of E. fullo in

Host plant‐specific volatiles of Beauveria bassiana‐colonized plants initiate trophic plant–aphid–predator cascades

Pest Management Science, EarlyView.
Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

The effect of the age of the serpentine leafminer Liriomyza trifolii (Diptera: Agromyzidae) on parasitism by the parasitoid wasp Gronotoma micromorpha (Hymenoptera: Figitidae: Eucoilinae)

European Journal of Entomology, 2009
Gronotoma micromorpha is a solitary egg-pupal and larval-pupal parasitoid. In a previous study, the developmental time of this parasitoid decreased with the age of its leaf miner host, Liriomyza trifolii, being significantly longer when the host was 0 ...

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

Pest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major

New Record of the Egg-larval Parasitoid, Chelonus formosanus Sonan of Fall Armyworm, Spodoptera frugiperda (J.E. Smith) in the Philippines

Jurnal Proteksi Tanaman, 2023
The egg-larval parasitoid on fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) have not reported in the Philippines. This paper summarizes the global biological information on two species of Chelonus and their role in the ...

Cannibalism in Buchananiella whitei (Hemiptera: Anthocoridae) and its intraguild interactions with seven predatory mites (Acari: Phytoseiidae & Laelapidae)

Pest Management Science, EarlyView.
Extraguild prey reduces cannibalism and intraguild predation in Buchananiella whitei, while first‐instar nymphs dominate most predatory mites, with outcomes affected by body size and behavioral traits. Abstract BACKGROUND Cannibalism and intraguild predation (IGP) are common interactions among predators that can influence the effectiveness of ...
