Wind direction, often used in forecasting locust migration, indicates a non-zero probability of desert locust invasion in eastern Indian states. Apart from present controlling measures, we are additionally suggesting to be cautious about the eggs of locust as the rainfall associated with Super Cyclone Amphan has created a favorable breeding ground for the gregarious locust. Also reverse migration [...]

Facultative predation can alter the ant-aphid population

Although ant--aphid interactions are the most typical example of mutualism between insect species, some studies suggest that ant attendance is not always advantageous for the aphids because they may pay a physiological cost. In this study, we propose a new mathematical model of an ant--aphid system considering the costs of ant attendance. It includes both mutualism and predation. In the model, we [...]

Epicuticular compounds of Protopiophila litigata (Diptera: Piophilidae): identification and sexual selection across two years in the wild

The epicuticular compounds (ECs) of insects serve both to waterproof the cuticle and, in many taxa, as pheromones that are important for various social interactions including mate choice within populations. However, ECs have not been individually identified in many species and most studies of their role in mate choice have been performed in a laboratory setting. Here we newly identify and [...]

Development time mediates the effect of larval diet on ageing and mating success of male antler flies in the wild

Christopher Angell, Mathieu Oudin, Nicolas O. Rode, et al.

High-quality developmental environments often improve individual performance into adulthood, but allocating toward early-life traits, such as growth, development rate, and reproduction, may lead to trade-offs with late life performance. It is therefore uncertain how a rich developmental environment will affect the ageing process (senescence), particularly in wild insects. To investigate the [...]

Natural variation in the growth and development of Protopiophila litigata (Diptera: Piophilidae) developing in three moose (Artiodactyla: Cervidae) antlers

Christopher Angell, Olivia Cook

Subjects: Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences, Population Biology

In animals, the early-life environment influences growth and development, which can have lasting effects on life history and fitness into adulthood. We investigated patterns of growth, pupal development time, and their covariation, in wild antler fly larvae (Protopiophila litigata; Diptera: Piophilidae) of both sexes collected from three discarded moose antlers of varying size, chewing damage [...]

Honey Bee Diversity Is Swayed by Migratory Beekeeping and Trade Despite Conservation Practices: Genetic Evidences for the Impact of Anthropogenic Factors on Population Structure

The intense admixture of honey bee (Apis mellifera L.) populations at a global scale is mostly attributed to the widespread migratory beekeeping practices and replacement of queens and colonies with non-native races or hybrids of different subspecies. These practices are also common in Anatolia and Thrace, but their influence on the genetic make-up of the five native subspecies of honey bees has [...]

Moving on from the insect apocalypse narrative: engaging with evidence-based insect conservation

Manu E. Saunders, Jasmine K Janes, James C O'Hanlon

Published: 2019-07-16
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences

Recent studies showing temporal changes in local and regional insect populations received exaggerated global media coverage. Confusing and inaccurate science communication on this important issue could have counter-productive effects on public support for insect conservation. The ‘insect apocalypse’ narrative is fuelled by a limited number of studies that are restricted geographically [...]
