What Goes First? Effects of Starvation on the Body Condition of a Neotropical Dung Beetle
We investigated how prolonged starvation affects key physiological traits in the dung beetle Dichotomius bos. Prolonged starvation leads to significant reductions in body dry mass and fat reserves, while muscle mass remains unchanged. These findings indicate that dung beetles prioritize the maintenance of locomotor muscles while mobilizing stored ...

Sélection de lignées à taux et durées de diapause différents chez Heliothis armigera Huebner (Lép. Noctuidae), souche d'origine tropicale, élevée à 25°C et 12 heures d'éclairement [PDF]
Une souche d'Heliothis armigera originaire de Côte d'Ivoire a été sélectionnée en deux lignées : l'une à faible taux de diapause, l'autre à fort taux de diapause.

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 ...

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

Molecular Correlates of Diapause in Aphidoletes aphidimyza
The aphidophagous gall midge, Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae), a dominant natural enemy of aphids, has been used as a biological control agent in many countries to control aphids in greenhouses.

Organisms living in temperate and polar environments encounter seasonal fluctuations that entail changes in temperature, resource availability, and biotic interactions. Thus, adaptations for synchronizing the life cycle with essential resources and persisting through unfavorable conditions are critical.

Butterfly Diversity in a Sacred Kaya Forest in Southern Kenya
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.

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 ...

Effect of temperature and photoperiod on growth, development and reproduction of Nysius huttoni White (Heteroptera: Lygaeidae) : a thesis presented in partial fulfilment of the requirement for the degree of Master of Applied Science in Plant Protection at the Institute of Natural Resources, Massey University, Palmerston North, New Zealand [PDF]
The influence of temperature, host plant and photoperiod on Nysius huttoni White growth, development and reproduction was investigated under laboratory conditions.
