Such a characteristic was a crucial condition to perform further steps aimed at preventing threats to thes...

In social species, the phenotypic diversity within a single species has often been associated with more complex genetic regulation. Transcription factors (TFs) being key to genetic regulation, have been studied in the origins of eusociality in Hymenoptera (Bees, Ants and Wasps) but less so in Blattodea (Cockroaches and Termites). Here we show that...

Doryctobracon fluminensis (Lima) is one of several species of braconid parasitoids of fruit flies occurring in Brazil. Nearly 60 years passed after the original description by Lima (1938) until the publication of new records of D. fluminensis in several Brazilian states. Species identifications in these records were generally based on the darkened...

Latitudinal diversity gradients are one of the most widely discussed patterns in global biogeography, generally in the context of high diversity in tropical regions. In contrast, ‘amphitropical’ or ‘inverse’ distributions, once thought to be unusual, are increasingly recognized as common among many hymenopteran insects. One such group is the ant ge...

New behavioural data shows that A. onosmarum is likely narrowly oligolectic on the plant genus Onosma (...

The european bee-eater (Merops apiaster) is an insectivorous bird species. Its diet predominantly includes representatives of insect groups such as Hymenoptera and Coleoptera. One of the most commonly used methods for studying the species composition of the european bee-eater's food base is the analysis of prey remains in pellets. However, the resu...

Context Increased cocoa cultivation (Theobroma cacao) has led to the conversion of over 6 million hectares of rainforest to cocoa farmlands in West Africa. Globally, pollinator decline has been driven by land use changes. Though land use change through cocoa expansion may affect insect pollinators and, by extension, pollination services, this has r...

The digger wasp Crossocerus barbipes (Hymenoptera: Crabronidae) has been found in the Netherlands after all! Crossocerus barbipes has been reported to be found in the Netherlands three times, but there were serious doubts on the identifications also because of the boreo-montane distribution of the wasp. One specimen has been lost during the second...

Arthropod biodiversity research usually requires large sample collections. The efficient handling of these samples has always been a critical bottleneck.

However, sweep netting requires the time-consuming task of sorting insects from the large amount...

The life history strategies of solitary and gregarious Microgastrinae parasitoids are both valued for their potential in biological control, but they have rarely been directly compared to fully understand their roles in integrated pest management (IPM) programs. This paper provides a detailed comparison of these two strategies, focusing on critical...
