Allee effects in an invasive social wasp: an experimental study in colonies of Vespula germanica [PDF]

Scientific Reports, 2023
Allee effects rely on the existence of mutually beneficial intraspecific interactions that increase individual fitness and per capita growth rate, as the number of individuals in a population or group increases. When the number of individuals falls below

Understanding key population drivers of the spotted wing Drosophila in cultivated and natural areas in the Andes [PDF]

Scientific Reports
The spotted-wing drosophila (SWD), Drosophila suzukii (Matsumara) (Diptera: Drosophilidae), is a serious global pest. Understanding the drivers for its success is fundamental to develop sustainable management tools.

Sugar responsiveness could determine foraging patterns in yellowjackets [PDF]

Scientific Reports, 2023
Sympatric-related species often exhibit resource partitioning. This can occur through different mechanisms, such as behavioral, morphological, and sensory variations, leading to qualitative, temporal, or spatial differences in resource exploitation, such

Environmental influence and species occurrence of yellowjacket drones in an invaded area [PDF]

Scientific Reports
During the mating season, reproductive individuals of numerous insect species gather in rendezvous areas, which increases mating opportunities. Male hymenopterans often have to move considerable distances during a particular season, searching or waiting ...

Sugar conditioning combined with nectar nonsugar compounds enhances honey bee pollen foraging in a nectarless diocious crop [PDF]

Scientific Reports
Recently, it has been shown that sugar‑conditioned honey bees can be biased towards a nectarless dioecious crop as kiwifruit. The challenges for an efficient pollination service in this crop species are its nectarless flowers and its short blooming ...

Identification of candidate genes associated with host-seeking behavior in the parasitoid wasp Diachasmimorpha longicaudata [PDF]

BMC Genomics
Background Diachasmimorpha longicaudata is a hymenopteran fruit fly endoparasitoid. Females of this species find their hosts for oviposition by using complex sensorial mechanisms in response to physical and chemical stimuli associated with the host and ...

Managed honeybees and South American bumblebees exhibit complementary foraging patterns in highbush blueberry

Scientific Reports, 2021
Despite Apis mellifera being the most widely managed pollinator to enhance crop production, they are not the most suitable species for highbush blueberries, which possess restrictive floral morphology and require buzz-pollination.

Effectiveness of Push–Pull Systems to Fall Armyworm (Spodoptera frugiperda) Management in Maize Crops in Morelos, Mexico

Insects, 2021
Chemical control is the main method used to combat fall armyworm in maize crops. However, its indiscriminate use usually leads to a more complex scenario characterized by loss of its effectiveness due to the development of resistance of the insect pest ...
