Abundance of Coccinellids and Their Potential Prey in Field-Crop and Grass Habitats in Eastern South Dakota [PDF]
, 2018 A rich fauna of coccinellids occurs in eastern South Dakota, but the abundance of some species has declined in association with the establishment of an exotic lady beetle, Coccinella septempunctata (L.) (Coleoptera: Coccinellidae), in the mid-1980s.

Entomologia Experimentalis et Applicata, Volume 174, Issue 11, Page 1322-1333, November 2026.MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

Ecology, Volume 107, Issue 10, October 2026.Abstract Climate change exacerbates heat waves, threatening ecosystems by disrupting species survival and interactions. Insects are highly sensitive to temperature extremes, exhibiting species‐specific stress which can impact community dynamics. Ecosystem services, such as pest control, can therefore be reduced by heat stress.

Alternative food sources for the ladybird Brumoides foudrasii (Mulsant) (Coleoptera: Coccinellidae)
Brazilian Journal of Biology, 2017 The predator Brumoides foudrasii (Mulsant) (Coleoptera, Coccinellidae) has been naturally found in plants infested by mealybugs. In this study, the striped mealybug Ferrisia dasylirii (Cockerell) (Hemiptera, Pseudococcidae) and Anagasta kuehniella Zeller

Entomological Science, Volume 29, Issue 3, September 2026.Ant presence was associated with lower gall density on Macaranga beccariana, whereas trees lacking ant defense had more galls and showed different parasitism patterns. Results from this natural experiment suggest that plant‐ants may indirectly influence gall midges through their effects on multitrophic interactions.

Impact and selectivity of insecticides on groundnut predators
Environment Conservation JournalPredatory arthropods play a crucial role in mitigating the impact of insect pests. However, the use of broad-spectrum insecticides in pest management methods can pose a threat to predator populations. In response to the need for safer and more selective

Journal of Applied Entomology, Volume 150, Issue 8, Page 1080-1087, September 2026.ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.
