Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related services can be maintained by a few dominant species or rely on high richness remains unclear. Using database from 89 studies (with 1475 locations), we partition the relative importance of richness, abundance, dominance for pollination; biological pest control; final yields in context ongoing land-use change. Pollinator enemy directly supported...
Significance Decades of research have fostered the now-prevalent assumption that noncrop habitat facilitates better pest suppression by providing shelter and food resources to predators parasitoids crop pests. Based on our analysis largest pest-control database its kind, surrounding farm fields does affect multiple dimensions control, but actual responses pests enemies are highly variable across geographies cropping systems. Because often not enhance biological more information about local...
Apis mellifera is composed of three evolutionary branches including mainly African (branch A), western and northern European M), southeastern C) populations. The existence morphological clines extending from the equator to Polar Circle through Morocco Spain raised hypothesis that branch M originated in Africa. Mitochondrial DNA analysis revealed A were characterized by highly diverged lineages implying very remote links between both branches. It also mtDNA haplotypes coexisted with Iberian...
Abstract Only a few of the registered insecticides against Cydia pomonella L. are still effective in areas where insecticide resistance has emerged this pest. Resistance mechanisms multiple, and their lone or cumulative effects single population not completely understood. A detailed estimation spectrum is required to define suitable use given population. The efficacy ten was therefore investigated together with expressed four laboratory strains 47 field populations C. from five countries....
Abstract The codling moth Cydia pomonella , a major invasive pest of pome fruit, has spread around the globe in last half century. We generated chromosome-level scaffold assembly including Z chromosome and portion W chromosome. This reveals duplication an olfactory receptor gene ( OR3 ), which we demonstrate enhances ability C. to exploit kairomones pheromones locating both host plants mates. Genome-wide association studies contrasting insecticide-resistant susceptible strains identify...
Complex landscapes including semi-natural habitats are expected to favour natural enemies thereby enhancing pest biocontrol in crops. However, when considering a large number of situations, the response landscape properties is globally inconsistent, possible explanation being that local agricultural practices counteract effects. In this study, along crossed gradient pesticide use intensity and simplification, we analysed interactive effects characteristics on biocontrol. During 3 years,...
The genetic variability of honeybee populations Apis mellifera ligustica, in continental Italy, and A. m. sicula, Sicily, was investigated using nuclear (microsatellite) mitochondrial markers. Six (236 individual bees) 17 (664 colonies) were, respectively, analysed eight microsatellite loci DraI restriction fragment length polymorphism (RFLP) the cytochrome oxidase I (COI)-cytochrome II (COII) region. Microsatellite globally confirmed southeastern European heritage both subspecies...
ABSTRACT Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related services can be maintained by few abundant species or rely on high richness remains unclear. Using a database from 89 systems, we partition the relative importance of abundance for pollination, biological pest control final yields in context on-going land-use change. Pollinator enemy directly supported independent abundance. Up 50%...
Abstract Until recently, African and European subspecies of the honeybee (Apis mellifera L.) had been geographically separated for around 10,000 years. However, human-assisted introductions have caused mixing large populations in South Central America, permitting an unprecedented opportunity to study a large-scale hybridization event using molecular analyses. We obtained reference from Europe, Africa, America used these provide baseline information microsatellite mitochondrial analysis...
Abstract The codling moth, Cydia pomonella , is renowned for developing resistance to insecticides and causing significant economic damage pome fruits worldwide. In spite of its importance, little known about the patterns movement this pest effects insecticide treatment on population genetic structure. Here, we investigated structure in 27 orchards from France, Italy, Armenia Chile at seven microsatellite loci two markers [biochemical activity cytochrome P450 oxidases proportion knockdown...
Abstract We investigated the taxonomic significance of nest shape and its putative role in speciation Trigona ( Heterotrigona ) carbonaria T. H. hockingsi , two sibling species stingless bee from eastern Australia. These are primarily distinguished by their architecture, as all other respects they nearly identical. genotyped 130 colonies six locations Queensland at 13 microsatellite loci together with 106 additional Indo‐Pacific species. Whether were present allopatry or sympatry, that...
Abstract The activity of detoxifying enzymes (glutathione-S-transferases (GST), mixed-function oxidases (MFO), and esterases (EST)) the presence insensitive variants target proteins (sodium channel acetylcholinesterase) were examined in individual male female codling moths. Twenty-nine populations from 11 countries two laboratory strains examined. Populations classified as either unsprayed or sprayed. ranges enzyme activities across field varied 15-fold, 485-fold fourfold for GST, MFO EST,...
Abstract Resistance to pesticides and drugs led the development of theoretical models aimed at identifying main factors resistance evolution predicting efficiency management strategies. We investigated various ways in which has been modelled over last three decades, by reviewing 187 articles published on all major classes drugs. found that (i) technical properties model were most strongly influenced class pesticide or drug target organism, (ii) strategies studied quite similar for different...
