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

Transcriptomic and Metabolomic Research on the Germination Process of Panax ginseng Overwintering Buds

Plants
Ginseng (Panax ginseng C. A. Meyer) is a perennial plant with a long dormancy period. While some researchers employ gibberellin and other substances to stimulate premature germination, this method is limited to laboratory settings and cannot be applied ...

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.

The impact of temperature on the reproductive development, body condition and mortality of autumn migrating monarch butterflies in the laboratory

Royal Society Open Science
Overwintering populations of the monarch butterfly, Danaus plexippus, have been in decline for the past 30 years. Several hypotheses for the decline have been proposed, including summer and winter habitat loss and migration mortality due to non-senescing

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

Pest Management Science, EarlyView.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

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

Effects of Eutrophication and Different Water Levels on Overwintering of Eichhornia crassipes at the Northern Margin of Its Distribution in China

Frontiers in Plant Science, 2019
When exotic species are introduced into new areas, establishment is a vital step in their invasion process. Therefore, overwintering strategies determine whether an exotic species from low latitudes can successfully invade middle- and high-latitude areas.

Assessing the potential for insecticide cross‐resistance to a novel insecticide in the Colorado potato beetle (Leptinotarsa decemlineata) using phenotypic and transcript expression analysis

Pest Management Science, EarlyView.
Phenotypic and transcriptional responses to imidacloprid and isocycloseram were examined across U.S. populations of the Colorado potato beetle, showing evidence of phenotypic cross‐resistance alongside population‐level variation in detoxification gene expression.

Overwintering temperature affects lipid and fatty acid metabolism in hepatopancreas and ovary of female mud crab Scylla paramamosain

Aquaculture Reports
The influence of four overwintering temperatures, namely 8 ℃, 12 ℃, 16 ℃, and 20 ℃, on lipid metabolism and fatty acid profile in the hepatopancreas and ovary tissues of female mud crab Scylla paramamosain was investigated during eight weeks.
