Instar Determination of the Neotropical Beetle Oxelytrum discicolle (Coleoptera: Silphidae)

Journal of medical entomology, 2010
The carrion beetle Oxelytrum discicolle (Brullé, 1840) has forensic importance in the Neotropical region. The age of their larvae can provide important information to estimate the minimum postmortem interval of the corpse.

Muffled olfactory and sensory cues from the reproductive stage soybean selectively reduce oviposition of a major polyphagous herbivore, fall armyworm (Spodoptera frugiperda)

Pest Management Science, EarlyView.
Fall armyworm (FAW) preferred ovipositing on vegetative‐stage soybeans. While ‘mother knows best’ may not apply in soybean‐FAW system, muffled cues in the reproductive stage could positively influence host success. Abstract BACKGROUND While the mother knows best/preference performance hypothesis has been well tested in natural ecosystems, how these ...

Investigating the threat to Sitka spruce from Ips typographus: discrimination and colonization of Britain's principal commercial conifer by a damaging forest pest

Pest Management Science, EarlyView.
The forest pest Ips typographus was found to demonstrate attraction to Sitka spruce, and to colonize and breed upon cut logs as successfully as its primary host Norway spruce. This has implications for the beetle's establishment and impact in Sitka‐growing regions, including Britain where I.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Attraction of cabbage stem flea beetle (Psylliodes chrysocephala) to host plant odors

Pest Management Science, EarlyView.
Oilseed rape (Brassica napus, OSR) cultivation in Europe is threatened by the cabbage stem flea beetle (Psylliodes chrysocephala, CSFB). Limited management options due to resistance and environmental concerns necessitate innovative control strategies. This study explores CSFB responses to volatile organic compounds (VOCs) emitted by host and non‐host ...
