Host plants and distribution records of lance flies (Diptera: Lonchaeidae) in São Paulo State, Brazil

open access: yesEntomoBrasilis, 2021
The knowledge of host plants, distribution and economic importance of Lonchaeidae is scarce in Latin America. We have recovered specimens of Lonchaeidae from most fruit samples containing specimens of Tephritidae.

Balancing risk and opportunity: Nasute termite responses to predator and competitor chemical cues

open access: yesEcological Entomology, EarlyView.
Nasutitermes corniger discriminates between heterospecific chemical cues during foraging, showing non‐random resource selection based on predator and competitor information. Predator chemical cues consistently reduce food resource selection, indicating avoidance driven by perceived predation risk rather than direct encounters.

She Doesn't Whisper: Female‐Prominent Stridulation Shaped by Morphology in a Buthid Scorpion and Insights on Its Function

open access: yesEthology, EarlyView.
Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.

The effects of Bacillus thuringiensis var. israelensis (Bti) on tropical stream food webs vary between two consecutive dry seasons

open access: yesInsect Conservation and Diversity, EarlyView.
Bti application altered tropical stream food‐web structure through changes in macroinvertebrate functional feeding groups. Collector‐filterers and predators showed context‐dependent responses, with clearer direct and indirect effects detected in 2016, the year with higher rainfall.

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

open access: yesMedical and Veterinary Entomology, EarlyView.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

Solenopsis saevissima (Smith) (Hymenoptera: Formicidae) Activity Delays Vertebrate Carcass Decomposition

open access: yesSociobiology, 2017
Ants are among the insects involved in cadaveric decomposition processes, as they exhibit predatory and necrophagous behavior. Red ants exhibit an aggressive behavior, which impacts carcass colonization, accelerates or delays the decomposition rates and ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of
