Towards edge processing of images from insect camera traps

Remote Sensing in Ecology and Conservation, EarlyView.
The advancement of light traps with camera‐based monitoring systems for nocturnal insects necessitates effective and flexible pipelines for analysing recorded images. In this paper, we present a flexible and fast processing pipeline designed to analyse these recordings by detecting, tracking and classifying insects in a broad taxonomy of 15 classes and

Activity schedule and foraging in Protopolybia sedula (Hymenoptera, Vespidae) [PDF]

, 2015
Protopolybia sedula is a social swarming wasp, widely spread throughout many countries in the Americas, including most of Brazil. Despite its distribution, studies of its behavioral ecology are scarce. This study aimed to describe its

Heterospecific Hymenoptera found inside the nests of Bombus impatiens (Hymenoptera: Apidae). [PDF]

, 2018
The nests of social Hymenoptera are particularly attractive to species engaging in resource robbing due to their concentration of resources. Here, the identity of heterospecific intruders in Bombus impatiens nests are described, with a particular focus ...

Polymorphism in Stelopolybia Areata (Hymenoptera, Vespidae) [PDF]

Psyche: A Journal of Entomology, 1974
Polymorphism in the social Hymenoptera has been defined as the occurrence within a single colony of two or more distinct morphological forms, or castes, belonging to the same sex (Wilson 953). Wilson (953) has pointed out that polymorphism arises out of the occurrence of allometry (differential rates of growth o.f two parts of the body) over a ...

Using total abundance as a proxy for wild bee species richness: A practical tool for non‐experts

Journal of Applied Ecology, EarlyView.
The use of a simple but effective proxy could be an important starting point for the expansion of wild bee monitoring initiatives at the regional scale, particularly given the growing involvement of non‐specialists. We provided here a simple implementation framework to use this proxy in rapid biodiversity assessments, such as the evaluation of payment ...

Camouflaged Nests of Mischocyttarus mirificus (Hymenoptera, Vespidae)

Neotropical Entomology, 2021
Social wasps present various architectural patterns for their nests, which may differ in shape, size, color, and material used in construction. The distribution pattern of comb cells presented by Mischocyttarus mirificus (Zikán, 1935) is vertical with a single cell of width, resulting in a filiform shape that camouflages in the middle of the substrate.

Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps

Insect Science, EarlyView.
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...
