Growing evidence for global pollinator decline is causing concern biodiversity conservation and ecosystem services maintenance. Neonicotinoid pesticides have been identified or suspected as a key factor responsible this decline. We assessed the exposure of pollinators to neonicotinoids by analyzing 198 honey samples from across world. found at least one five tested compounds (acetamiprid, clothianidin, imidacloprid, thiacloprid, thiamethoxam) in 75% all samples, 45% contained two more these...
Alien insects are increasingly being dispersed around the world through international trade, causing a multitude of negative environmental impacts and billions dollars in economic losses annually. Border controls form last line defense against invasions, whereby inspectors aim to intercept stop consignments that contaminated with harmful alien insects. In Europe, member states depend on one another prevent insect introductions by operating first point entry rule – controlling goods only when...
1. Arthropods are important players in biological control as pests, agents and transmitters of invertebrate diseases. frequently infected with one or several micro-organisms, serving micro-ecosystems which multiple interactions can take place. These micro-organisms include disease symbiotic micro-organisms. The latter usually vertically transmitted have a broad spectrum effects on their hosts, ranging from reproductive manipulations to protection against natural enemies. may directly...
Abstract Aim To quantify the relative importance of propagule pressure, climate‐matching and host availability for invasion agricultural pest arthropods in Europe to forecast newly emerging species European areas with highest risk arthropod under current climate a future scenario ( A 1 F 1). Location Europe. Methods We quantified by aggregating large global databases trade, interceptions, Koeppen–Geiger world classification (including change until 2100) plant distributions 118 quarantine...
Drosophila suzukii is an invasive fly of East Asian origin that has become a serious fruit pest worldwide. Classical biological control through the introduction parasitoids from Asia could help reduce populations D. in invaded regions. Little known about native Asia. Therefore, surveys for larval were carried out China and Japan between 2015 2017. Parasitoids other fruit-inhabiting drosophilids (D. pulchrella subpulchrella) are probably attacked by same parasitoid complex found four Chinese...
Abstract Background Neonicotinoids (NN) are selective neurotoxic pesticides that bind to insect but also mammal nicotinic acetycholine receptors (nAChRs). As the most widely used class of insecticides worldwide, they ubiquitously found in environment, wildlife, and foods, thus special concern for their impacts on environment human health. nAChRs vital proper brain organization during prenatal period play important roles various motor, emotional, cognitive functions. Little is known...
The globally invasive chestnut gall wasp Dryocosmus kuriphilus was recently reported in Italy and threatens European orchards native forests. Of Chinese origin, this species has invaded Japan, Korea, the USA, Nepal Europe each region it been attacked by parasitoids exploiting oak wasps. Classical biological control using parasitoid Torymus sinensis (Hymenoptera: Torymidae) successfully reduced infestation Japan. Subsequent work Japan Korea showed to represent a poorly understood biologically...
Declining plant species richness in agro‐ecosystems and thus reduced habitat quality can have cascading effects on ecosystem functioning, leading to pollination biological control. Here we test if diversity affect arthropod abundance a very small scale, manipulating (2, 6, 12 20 sown species) adjacent subplots (6 × 9 m) 10 wildflower strips an agricultural landscape. We simultaneously analyzed the effect of richness, vegetation structure, composition cavity‐nesting wild bees, wasps, their...
Abstract The oak gallwasp Andricus coriarius is distributed across the Western Palaearctic from Morocco to Iran. It belongs a clade of host‐alternating species that requires host oaks in two sections Quercus subgenus complete its lifecycle, requirement has restricted historic distribution and dispersal members this clade. Here we present nuclear mitochondrial sequence evidence entire geographic range A. investigate genetic legacy longitudinal expansion. We show as currently understood be...
Methods for the evaluation and comparison of structure numerous honeybee colonies are needed development applied fundamental field research, as well to evaluate how activity evolve over time. ColEval complements existing methods, it uses an online reference image bank (human) learning training purposes. is based on surface area percentage occupied by different components a colony: adult worker bees, open capped brood, honey, nectar, pollen. This method essential tool description evolution in...
The ectoparasitic mite Varroa destructor affects honey bee colony health and survival negatively, thus compelling beekeepers to treat their colonies every year. A broadly used control regimen is based on two organic molecules: formic oxalic acids. To ensure optimal efficiency, several applications of these acids at pre-defined time points are recommended. These recommendations mainly experiments conducted under controlled conditions. Studies evaluating the effectiveness natural field...
Endosymbiotic reproductive manipulators may have drastic effects on the ecological and evolutionary dynamics of their hosts. The prevalence these endosymbionts reflects both ability to manipulate hosts history host populations. little fire ant Wasmannia auropunctata displays a polymorphism in its system (sexual versus clonal populations) invasive status populations (associated habitat shift). We first screened for presence diverse array parasites sexual W. auropunctata, as means investigate...
Wildflower strips are used to increase natural enemies of crop pests and conserve insect diversity on farmland. Mollusks, especially slugs, can affect the vegetation development in these considerably. Although recent theoretical work suggests that more diverse plant communities will exhibit greater resistance against herbivore pressure, empirical studies scarce. We conducted a semi-natural experiment wildflower strips, manipulating trophic structure (reduction herbivorous mollusks reduction...

Acanthoscelides Schilsky is a large genus of neotropical bruchid beetles, in which most species show host plant specialization. obtectus and obvelatus are two sibling specialized on Phaseolus beans, therefore considered pests. Up to now, the status these taxa has remained unclear, few studies conducted having failed elucidate whether differentiated or single morphologically variable species. In addition, A. not been taken into account great majority bean bruchids. this morphological genetic...
