Drosophila suzukii is a global invasive pest of soft-skinned and small stone fruits. Fly larvae fall from fruit to the soil to pupate, after which time adults emerge. Biological control of D. suzukii larvae with entomopathogenic nematodes has been reported in previous studies with positive results, but susceptibility of adults has still not been evaluated. In this study, the susceptibility of mature adults to Heterorhabditis bacteriophora, Steinernema feltiae and S. carpocapsae was tested. We al...
The invasive vinegar fly Drosophila suzukii not only infests and damages numerous fruit crops but also develops in many wild fruit species in semi-natural habitats. Biological control in these refuges could reduce D. suzukii populations and minimize their dispersal into fruit crops. We investigated parasitization of D. suzukii by the pupal parasitoid Trichopria drosophilae in seven common wild fruit species. Development and nutrient content of D. suzukii differed among the fruit species. Neverth...
The red palm weevil (RPW), Rhynchophorus ferrugineus, an oligophagous borer that specifically attacks the Arecaceae family, poses a serious threat to commercial and ornamental palms. Originally from tropical Asia, the RPW has spread to Africa and Europe, reaching the Mediterranean region 30 year ago. Characterizing its spread is a key aspect of effectively managing its geographical expansion. Using georeferenced RPW occurrence data from 2012 to 2013 in Israel, we sought to better understand its ...
Nitrogen fertilizers are widely used to maximize crop productivity but are also known to benefit pest insects. Here we show that nitrogen not only increased the egg size of the key pest, brown planthopper (BPH), Nilaparvata lugens Stal, but also benefitted the predatory mirid bug, Cyrtorhinus lividipennis Reuter (Hemiptera: Miridae). Predator nymph survival and development rate, female adult weight, longevity and fecundity were all enhanced. Importantly, however, high nitrogen levels also extend...
The Asian corn borer, Ostrinia furnacalis, is a serious pest and is widely distributed in corn-producing regions throughout China. This insect enters facultative diapause as fully grown larvae in response to short day lengths. Here, we evaluate the changes in diapause incidence and critical day length (CDL) by crossing a tropical strain with five subtropical and temperate strains from a 2897-km latitudinal gradient to investigate the latitudinal variations in diapause induction and CDL and their...
Colorado potato beetle (CPB; Leptinotarsa decemlineata) has been detected in Xinjiang, China, since 1993 and has caused serious damage to potato production during its eastward expansion to new geographic ranges. Symbiotic bacteria often play an essential role for insects to exploit novel food sources and expand into otherwise inaccessible ecological niches. An important yet unresolved question is whether herbivore populations from different geographic ranges have distinct or equal abilities to a...
The invasive khapra beetle, Trogoderma granarium, is an economically destructive species and the only stored product insect pest that is quarantined in the USA. In the past several decades, there have been an increasing number of interceptions of T. granarium at ports in the USA. The established trap and lure used for surveillance of T. granarium in high risk areas was developed 30 years ago, but since then new lures containing food and/or pheromonal stimuli have become available. In the USA, re...
Honeydew is a sugar-rich food source produced by sap-feeding insects, notably by major pests such as aphids and whiteflies. It is an important alternative food source for the adult stage of various key natural enemies (e.g., parasitoids), but it may be used also as food by agricultural pests. Necremnus tutae is an idiobiont parasitoid, and it is the most abundant larval parasitoid associated with the South American tomato pinworm, Tuta absoluta, in recently invaded European areas. The impact of ...
A clearer understanding of the structure of pest populations in newly invaded areas is a key step towards their effective management. Here, we use Drosophila suzukii as a model to highlight how populations from separate geographical regions differ in their genetic and phenotypic traits, including those associated with their invasiveness. New X-linked data indicate the presence of at most three D. suzukii genetic clusters in Europe, while North American populations are characterised by a larger g...
