Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

Ecological Entomology, Volume 51, Issue 2, Page 346-355, April 2026.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

Biological aspects of Tiracola grandirena (Herrich-Schäffer, 1868) (Lepidoptera: Noctuidae): a polyphagous armyworm

Brazilian Journal of Biology
We studied the biology of Tiracola grandirena(Herrich-Schäffer, 1868) (Lepidoptera: Noctuidae: Hadeninae) at 25 ± 1 °C, 70 ± 10% RH and 14 hours of photo phase. Three experiments, using 150 larvae each, were conducted for the larval stage.

Effect of temperature on growth and development of rice weevil [Sitophilus oryzae (L.) (Coleoptera: Curculionidae)] on polished rice

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Rice weevils (Sitophilus oryzae), a major storage pest, cause both qualitative and quantitative losses of stored grains. Normally, chemical insecticide along with fumigation is practiced for the management, but it creates health hazards. So, this study investigates the effects of temperature and duration of exposure on rice weevils. Completely

Butterfly Diversity in a Sacred Kaya Forest in Southern Kenya

Ecology and Evolution, Volume 16, Issue 3, March 2026.
In this study we analysed the butterfly communities in a tropical coastal forest patch and the surrounding anthropogenic ecosystems. Although both abundance and species richness were lowest inside the natural forest, vulnerable forest specialists were restricted to the forest interior and absent from all anthropogenic landscapes.

Drought‐driven lipid deficits in overwintering monarch butterflies revealed by δ2H and fatty acid analysis

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Eastern populations of monarch butterflies (Danaus plexippus) overwinter in the central trans‐volcanic belt of Mexico, relying primarily on lipids accumulated during migration to sustain this several‐month‐long overwintering period. This study shows how drought conditions in north‐central Mexico influenced lipid dynamics in monarchs ...

Prolonged Heat Stress during Winter Diapause Alters the Expression of Stress-Response Genes in Ostrinia nubilalis (Hbn.)

International Journal of Molecular Sciences
During diapause, a state of temporarily arrested development, insects require low winter temperatures to suppress their metabolism, conserve energy stores and acquire cold hardiness. A warmer winter could, thus, reduce diapause incidence and duration in many species, prematurely deplete their energy reserves and compromise post-diapause fitness.

Regulation of the juvenile hormone titre in the Colorado potato beetle [PDF]

, 1978
Three main topics were investigated in regulation of the titre of juvenile hormone in haemolymph of the Colorado potato beetle ( Leptinotarsa decemlineata Say): enzymic breakdown of the hormone; binding and protection of the hormone by carrier proteins ...

Phenological shifts and increases in voltinism within a moth community over a century of anthropogenic change

Ecology, Volume 107, Issue 3, March 2026.
Abstract In temperate ecosystems, warming temperatures can advance spring phenology, extend autumn phenology, disrupt dormancy regulation, result in phenological mismatch across taxa, and even lead to increases in the number of generations per year (i.e., increases in voltinism).

Adaptive responses to environmental variability in rotifers: Integrating plasticity and bet hedging in dormancy exit

Ecology, Volume 107, Issue 3, March 2026.
Abstract Environmental variability imposes strong selective pressures that may favor adaptive responses such as phenotypic plasticity and bet hedging. Plasticity is generally favored under predictable conditions, whereas bet hedging is advantageous against environmental uncertainty. Plastic responses rely on reliable cues to adjust phenotypes to future
