Insect Management for Leafy Vegetables (Lettuce, Endive and Escarole)
EDIS, 2005 Damage to leafy vegetables results from holes chewed in leaves by caterpillars and beetles, leaf mining by fly larvae and disease transmission and head contamination by piercing sucking insects. Major pests of these crops are beet and southern armyworms,

Intestinal Bacterial Diversity and Functional Analysis of Three Lepidopteran Corn Ear Worm Larvae
Insects, 2022 Insects, as the most abundant animal group on earth, and their symbionts help their hosts to adapt to various environments. Conogethes punctiferalis, Ostrinia furnacalis and Helicoverpa armigera are three main pests co-occurring in the ear stage of corn,

Neonicotinoids can cause arrested pupal ecdysis in Lepidoptera
Scientific Reports, 2021 Recently, we reported a novel mode of action in monarch butterfly (Danaus plexippus) larvae exposed to neonicotinoid insecticides: arrest in pupal ecdysis following successful larval ecdysis.

Spatial distribution and losses by grain destroying insects in transgenic corn expressing the toxin Cry1Ab. [PDF]
PLoS ONE, 2018 Insect pests are one of the factors that most impact plant yield. The magnitude of the losses and the spatiotemporal pest distribution in crops is a result of their interactions with the environment.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive
