Insect Science, EarlyView.Abstract Circadian rhythms are self‐sustained endogenous oscillations that are found in all living organisms. In insects, circadian rhythms control a wide variety of behavioral and physiological processes, including feeding, locomotion, mating, and metabolism.

Freshwater Biology, Volume 68, Issue 2, Page 325-339, February 2023., 2023 Abstract Worldwide, riparian zones of many intermittent rivers and ephemeral streams (IRES) have been severely degraded. However, compared with perennially flowing waters, there have been few restoration efforts (e.g., revegetation, livestock removal) to halt or reverse this degradation.

Frequency and Viability of Diploid and Haploid Males Offsprings of Mated Females of Solitary Endoparasitoid (DIADROMUS Pulchellus) (Ichneumonidae) [PDF]
Comptes Rendus de l'Academie des Sciences. Serie 3, Sciences de la
Vie 324 (2001) 149-158, 2006 Sex determination in the order Hymenoptera is based on arrhenotoky, hymenopteran males are usually haploid and females diploid. Males of the Ichneumonidae Diadromus pulchellus, solitary endoparasitoid of A. assectella pupae are normally haploid, but diploid males are present in a natural population and can be obtained in a experimental population.

Development of Eye Colors in Drosophila: Extraction of the Diffusible Substances Concerned [PDF]
, 1937 The development of eye color in Drosophila is known to involve special diffusible substances [1,2]. A genetically vermilion (v) eye will develop wild-type eye color if it is supplied with v+ substance by transplantation or by injection of body fluid of ...

Foraging by predatory ants: A review
Insect Science, EarlyView.This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics
Global Change Biology, Volume 29, Issue 2, Page 308-323, January 2023., 2023 Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...

Mechanical state, material properties and continuous description of an epithelial tissue [PDF]
arXiv, 2012 During development, epithelial tissues undergo extensive morphogenesis based on coordinated changes of cell shape and position over time. Continuum mechanics describes tissue mechanical state and shape changes in terms of strain and stress. It accounts for individual cell properties using only a few spatially averaged material parameters.

Insect Science, EarlyView.• We explored intraspecific variation of thermal tolerance among populations of a widespread diving beetle across an elevational gradient.• We found no evidence of local adaption of thermal tolerance along the elevational gradient and limited plasticity of thermal limits.• Our results suggest thermal niche conservatism as a result of gene flow or ...

Eco control of agro pests using imaging, modelling & natural predators [PDF]
, 2014 Caterpillars in their various forms: size, shape, and colour cause significant harm to crops and humans. This paper offers a solution for the detection and control of caterpillars through the use of a sustainable pest control system that does not require
