Since its accidental introduction in 2003 in France, the yellow-legged Asian hornet Vespa velutina nigrithorax is rapidly spreading through Europe. In a new paper, published in the open-access journal Neobiota, French scientists try to estimate the costs of the invasion regarding the potential damage to apiculture and pollination services.
With 3,000 known species and thousands more left to describe, the wasps of the subfamily Microgastrinae are the single most important group of parasitoids attacking the larvae of butterflies and moths, many of which are economically important pests. Consequently, these wasps have a significant impact on both the world’s economy and biodiversity. Due to their […]
Insects rely on a mix of floral resources for survival. Populations of bees, butterflies, and flies are currently rapidly decreasing due to the loss of flower-rich meadows. In order to deal with the widespread loss of fauna, the European Union supports “greening” measures, for example, the creation of flower strips. A group of scientists from the University […]
Known to prey on many insects, including honey bees and other beneficiary species, the Asian hornet, which had recently invaded parts of Europe, presents a serious threat to apiculture and even to ecosystems. In their paper, published in the open-access journal Evolutionary Systematics, German scientists share concerns about this fast invader spreading to the north. In early September 2019, a single specimen was collected alive in Hamburg (Germany), representing the northernmost find of the species so far.
About 120 clusters of 19th-century orchid bee nests were found during restoration work on the altarpiece of Basilica Cathedral in Casco Viejo (Panamá). Having conducted the first pollen analysis for these extremely secretive insects, the researchers identified the presence of 48 plant species, representing 23 families.
Specimens kept in the collection of the Institute of Beneficial Insects at the Fujian Agriculture and Forestry University (FAFU, China) revealed the existence of two previously unknown species of endoparasitoid wasps. Originally collected in 2013, the insects are known to inhabit prairies and bushes at above 3,400 m, which is quite an unusual altitude for this group […]
Thought to be Canada’s most promising potential defense against the brown marmorated stink bug – a globally spreading agricultural pest native to Asia – the samurai wasp (another species from Asia and natural parasitoid of the former) has been considered for future release in the country in recent years. However, prior to any formal decision […]
Important group of biocontrol wasps from Central Europe are used to demonstrate the perks and advantages of modern, free-to-use software Representing a group of successful biocontrol agents for various pest fruit flies, a parasitic wasp genus remains largely overlooked. While its most recent identification key dates back to 1969, many new species have been added […]
As many as twenty-one species of parasitoid wasps are described as new to science, following the first ever revision of their genus since its establishment back in 1893. The study simultaneously updates the count of species within the genus (Chromoteleia) to 27 in total, produces a systematic revision of the world’s representatives of this group […]
Scientists report this behavior for the first time in the genus Nomada, following both lab and field observations in Germany One can seldom spot a cuckoo bee, whose peculiar kleptoparasitic behaviour includes laying eggs in the nests of a certain host bee species, let alone a couple mating. Nevertheless, German scientists – Dr. Matthias Schindler, University […]
