Structural and ultrastructural studies of Anticarsia gemmatalis midgut cells infected with the baculovirus A. gemmatalis nucleopolyhedrovirus [PDF]

open access: yesInternational Journal of Insect Morphology and Embryology, 1999
Anticarsia gemmatalis is a lepidopteran insect susceptible to A. gemmatalis nucleopolyhedrovirus (AgNPV), which is being used in a large scale, in Brazil, as a biological control agent against this serious soybean pest. Baculovirus usually infects its insect host through the midgut epithelium.

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

open access: yesPest Management Science, Volume 81, Issue 11, Page 7403-7413, November 2025.
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 ...

Seed Production and Pollinator Dependence in Native Wildflowers: Guiding Species Selection for Conservation Plantings

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We investigated the pollination biology of eight native wildflower species in the southeastern U.S. to assess their dependence on insect pollinators and potential for self‐pollination. Most species showed significantly higher seed production and weight when open‐pollinated, indicating strong pollinator dependence, though some could reproduce without ...

Insect immunity in the Anthropocene

open access: yesBiological Reviews, Volume 100, Issue 2, Page 698-723, April 2025.
ABSTRACT Anthropogenic activities result in global change, including climate change, landscape degradation and pollution, that can alter insect physiology and immune defences. These changes may have contributed to global insect decline and the dynamics of insect‐transmitted diseases.
