Effects of Insecticides on Pest Populations and Their Natural Enemies in Soybean Field [PDF]

, 1987
In the 5-time field experiments and broad demonstrations, effects of volume and application formulae of several pesticides on the population densities of major inset pests and natural enemies in the soybean field were determined. Results from the Ducan’s

Rethinking intensification: Biodiversity‐inclusive management sustains coconut yields

PLANTS, PEOPLE, PLANET, EarlyView.
Coconut palm expansion in West Africa will shape rural livelihoods and ecosystems. Our findings show that intensive practices reduce beneficial soil fungi and increase pathogens, threatening long‐term productivity. Lower‐intensity management that retains ground vegetation can sustain or boost yields while improving soil health.

Transfer and biological effects of cadmium along a tomato – thrip – predatory bug food chain

Ecotoxicology and Environmental Safety
The heavy metal, cadmium (Cd) is an increasingly serious issue in agricultural ecosystems, mediating bottom-up effects on plants, herbivores and natural enemies. We measured how Cd modifies interactions between tomato Solanum lycopersicum, western flower

Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

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.

Intestinal bacterium Bacillus siamensis M54 from Allomyrina dichotoma is a potential biocontrol agent against maize stalk rot

Biological Control
Maize stalk rot, caused by Fusarium spp., is a significant disease that adversely impacts the yield and quality of corn. Biological control plays a crucial role in managing numerous crop diseases, including maize stalk rot.

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.

Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

Pest Management Science, EarlyView.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...
