Abstract Climate warming is considered to be among the most serious of anthropogenic stresses environment, because it not only has direct effects on biodiversity, but also exacerbates harmful other human‐mediated threats. The associated consequences are potentially severe, particularly in terms threats species preservation, as well preservation an array ecosystem services provided by biodiversity. Among affected groups animals insects—central components many ecosystems—for which climate...
Boivin, G., Hance, T. and Brodeur, J. 2012. Aphid parasitoids in biological control. Can. Plant Sci. 92: 1–12. Aphids are important pests of most cultivated crops worldwide. Among the natural enemies that regulate their populations, aphid commonly used control programs greenhouses field situations. They belong to Hymenoptera (Braconidae Aphelinidae), a few species Diptera (Cecidomyiidae). themselves exposed variety including predators, fungi hyperparasitoids. The impediment use as agents...
Frankliniella veracrucensis sp. n. is described from flowers of Salvia leucantha [Lamiaceae] in Veracruz, Mexico. This the fourth species known with seven antennal segments, and a key to antennae 7-segmented provided.
Abstract The impact of fluctuating thermal regimes on the cold tolerance parasitoid Aphidius colemani at mummy stage is examined. hypothesis tested that, if a period interrupted by return to higher temperature for short time, physiological recovery possible and may lead survival. Mummies are exposed constant 4 °C and, when periodic sudden transfers 20 2 h applied, survival immature parasitoids markedly improved, proportionally warming frequency. time lag before emergence diminishes with...

Tetranychus urticae is a phytophagous mite that forms colonies of several thousand individuals. These mites construct common web to protect the colony. When plants become overcrowded and food resources scarce, individuals gather at plant apex form ball composed their silk threads. This structure facilitating group dispersal by wind or animal transport. Until now, no quantitative study had been done on this collective migration. first attempt understand mechanisms underlie emergence growth...
Aphids feed on the phloem sap of plants, and are most common honeydew-producing insects. While aphid honeydew is primarily considered to comprise sugars amino acids, its protein diversity has yet be documented. Here, we report investigation proteome from pea Acyrthosiphon pisum. Using a two-Dimensional Differential in-Gel Electrophoresis (2D-Dige) approach, more than 140 spots were isolated, demonstrating that also represents diverse source proteins. About 66% isolated identified through...
Symbiosis is a common phenomenon in nature that substantially affects organismal ecology and evolution. Fundamental questions regarding how mutualistic associations arise evolve remain, however, poorly studied. The aphid-Serratia symbiotica bacterium interaction represents valuable model to study mechanisms shaping these symbiotic interspecific interactions. S. strains capable of living independently aphid hosts have recently been isolated. These probably resulted from horizontal transfers...
In addition to its obligatory symbiont Buchnera aphidicola, the pea aphid Acyrthosiphon pisum can harbor several facultative bacterial symbionts which be mutualistic in context of various ecological interactions. Belonging a genus where many members have been described as pathogen invertebrates, Serratia symbiotica is one most common partners found aphids. The recent discovery strains able grow outside their host allowed us simulate environmental acquisition symbiotic bacteria by Here, we...
The granary weevil Sitophilus granarius is a stored product pest found worldwide. Environmental damages, human health issues and the emergence of resistance are driving scientists to seeks alternatives synthetic insecticides for its control. With low mammal toxicity persistence, essential oils more being considered potential alternative. In this study, we compare 25 oils, representing large array chemical compositions, on adult weevils. Bioassays indicated that Allium sativum was most toxic...
Abstract Symbioses are significant drivers of insect evolutionary ecology. Despite recent findings that these associations can emerge from environmentally derived bacterial precursors, there is still little information on how potential progenitors symbionts circulate in trophic systems. Serratia symbiotica represents a valuable model for deciphering scenarios acquisition by insects, as its diversity includes gut-associated strains retained the ability to live independently their hosts,...
An intracellular symbiotic bacterium was isolated from the flora of a natural clone black bean aphid Aphis fabae . The strain able to grow freely in aerobic conditions on rich medium containing 1 % each following substrates: glucose, yeast extract and casein peptone. Pure culture achieved through use solid-phase same designated CWBI-2.3 T 16S rRNA gene sequence analysis revealed that member class Gammaproteobacteria, having high similarity (>99 %) with ‘ Candidatus Serratia symbiotica’,...
The incidence of tick-borne diseases is increasing in Europe. Sub national information on tick distribution, ecology and vector status often lacking. However, precise location infection risk can lead to better targeted prevention measures, surveillance control. In this context, the current paper compiled geolocated occurrences Belgium, a country where disease has received little attention, order highlight potential value spatial approaches draw some recommendations for future research...
The two-spotted spider mite Tetranychus urticae Koch is a worldwide pest, feeding on large variety of plant families. As its resistance to acaricides spreads rapidly, it crucial develop new biological control tactics manage populations. In this respect, essential oils may be good alternative, as they are currently considered minimum-risk pesticides. paper, we conducted series laboratory experiments determine the susceptibility adult females 31 extracted from plants collected Tunisia and...
The diapause of Aedes albopictus is maternally induced by photoperiod and initiates at the pharate larvae stage in eggs. This pre-diapause results enhanced survival eggs during winter. study aims to disentangle effects on embryonic developmental time egg size A. albopictus. A temperate strain capable perform a tropical unable were reared 21°C with long-(LD) short-day (SD) lengths. Four distinct traits studied embryos measured end embryogenesis.The chronologies embryo development for both...
In temperate areas, population dynamics of the invasive Asian tiger mosquito Aedes albopictus are strongly affected by winter. The work we present here analyzes adaptive synchronization diapause process in wintry generation A. albopictus, where egg stage is exposed to adverse winter conditions. seasonal pattern laying activity a French Mediterranean was monitored weekly for 2 years with ovitraps. field incidence and critical photoperiod (CPP, i.e. maternal day length inducing 50% eggs), were...
