Subject:
Adoxophyes honmai; altitude; entomology; males; moths; odors; reflectance; sex pheromones; tea; wavelengths
Abstract:
... Insects control their flight toward a distant odour source by integrating multimodal sensory information, such as olfactory and visual information. Control of flight speed in orientation flight toward an odour source using visual patterning below has been observed in many species of moths. However, there are few reports about moth flight behaviour over solid‐coloured floors. To examine, which visu ...

Abstract:
... The study of desiccation resistance and its underlying traits is key to understanding species responses to changes in water availability, especially in the context of predicted increases in the frequency and severity of droughts due to climate change. We performed laboratory experiments using dung beetles, important ecosystem service providers, to investigate variations in physiological traits wit ...

Abstract:
... The role of desensitization in mating disruption (MD) of European Grapevine Moth (EGVM), Lobesia botrana (Dennis and Schiffermüller) (Lepidoptera: Tortricidae), is studied by exposing males to different airborne pheromone concentrations for various time intervals prior to evaluate their behavioural response. By using different types of dispensers, male moths are exposed to three decreasing pheromo ...

Abstract:
... The ubiquitous use of agrochemicals is one driver for the ongoing loss of insect biomass and diversity. Data show that field‐realistic concentrations of neonicotinoid insecticides can negatively affect both population density and the fitness of solitary bees. However, the underlying mechanisms for these effects remain poorly understood. Here, using an established semi‐field experimental set‐up and ...

Abstract:
... Male accessory gland (MAG) secretory proteins affect female reproductive physiology and behaviour when they are delivered to the female at the time of mating along with sperm. In our study, proteomic approaches were used to identify MAG proteins of Leucinodes orbonalis, a monophagous and destructive pest of brinjal. A set of 117 and 186 MAG spots were observed in virgin and mated males, respective ...

Abstract:
... Methoprene, a juvenile hormone analog, accelerates male sexual maturation in some pest species controlled through the Sterile Insect Technique (SIT). The SIT consists of the mass‐rearing, irradiation and release of insects into affected areas, where sterile males mate with wild females and render them infertile. Sterile males are held for 6 days in confinement before release, and they are often re ...

Manduca sexta; copulation; entomology; females; males; mechanics; moths; spermatheca; spermatophores; spermatozoa; travel
Abstract:
... During mating in the Lepidoptera (moths and butterflies), sperm are passed to the female via a copulation in which the male transfers a large and often complex spermatophore over the major part of an hour or more. Subsequently, over the course of an hour or often considerably more, the sperm exit the spermatophore and travel over a relatively complex route to the spermatheca, where the sperm are s ...

Abstract:
... Bark beetles (Coleoptera: Curculionidae: Scolytinae) are a speciose subfamily of weevils that primarily live in bark and consequently largely communicate using sound. Having colonized multiple countries outside its native range, Hylurgus ligniperda (Fabricius) is considered to be a successful invader, yet little is known about its acoustic communication. In the present study, we investigate indivi ...

The sex pheromone produced by S. frugiperda is composed of a mixture of esters. In this study, I determined the antennal responses of FAW males from 22 populations in Mexico to the components of the sex pheromone of this species: (Z)‐ ...
