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.

EFFECT OF SOIL TYPE, MOISTURE AND SAND COVER ON PUPATION DEPTH, SURVIVAL OF PUPAE AND ADULTS OF ZIZYPHUS FRUIT FLY, Carpomyia incompleta BECKER UNDER LABORATORY CONDITIONS [PDF]

Journal of Plant Protection and Pathology, 2013
The current study indicated that the most suitable soil type and moisture level for the emergence of Zizyphus fruit fly (ZFF), Carpomyia incompleta Becker (Diptera: Tephritidae) was the sandy soil containing 15% water.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Description of the preimaginal stages and biology of the weevil Lixus (Dilixellus) pulverulentus (Scopoli, 1763) (Coleoptera: Curculionidae: Lixini) [PDF]

Кавказский энтомологический бюллетень, 2017
Last instar larva and pupa of Lixus pulverulentus (Scopoli, 1763) are described and illustrated for the first time. Larvae and pupae were collected in Rostov Region (Southern Russia) on host plants Cirsium serrulatum and Carduus acanthoides.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Morphology of the preimaginal stages of weevils of the tribe Cleonini sensu lato (Coleoptera: Curculionidae) [PDF]

Кавказский энтомологический бюллетень, 2011
This article is devoted to study of preimaginal stages of weevil Cleonini sensu lato. It includes morphology and biology of 5 species: Rhabdorhynchus karelini (Fåhraeus, 1842), Cyphocleonis achates (Fåhraeus, 1842), Bothynoderes affinis (Schrank, 1781 ...

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

Pest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

Effects of pupal hypoxia duration and holding temperature on quality control parameters of sterile Queensland fruit fly

Pest Management Science, EarlyView.
Queensland fruit fly pupae tolerate hypoxia up to 2 days without compromising quality. Prolonged hypoxia, especially at 25 °C, reduces emergence and flight ability. Storage at 18 °C is recommended. Abstract BACKGROUND The sterile insect technique is used to eradicate outbreaks of Queensland fruit fly (Q‐fly) Bactrocera tryoni (Froggatt) in fruit‐fly ...
