Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) also known as spotted-wing drosophila (SWD), is a pest native to Southeast Asia. In the last few decades, has expanded its range affect all major European and American fruit production regions. SWD highly adaptive insect that able disperse, survive, flourish under of environmental conditions. Infestation by generates both direct indirect economic impacts through yield losses, shorter shelf life infested fruit, increased costs. Fresh...
Abstract Spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is originally from Asia, and in the last decade it has become a global economic pest of small fruits cherries. Growers have expressed strong interest biological control other sustainable tactics to reduce reliance on insecticides. Biological spotted-wing drosophila been studied intensively, with over 75 research publications. Here, we are reporting current information predators, parasitoids, pathogens...
The commercialization of natural enemies and their increased use in pest management present applied entomologists ecologists with formidable challenges. A response to these challenges requires reducing the cost mass-rearing manipulating enemies; improving success rate predictability biological control procedures; demonstrating effectiveness, ecological benefits, safety under commercial conditions.
Abstract 1. The Argentine ant, Linepithema humile , tends honeydew‐excreting homopterans and can disrupt the activity of their natural enemies. This mutualism is often cited for increases in homopteran densities; however, ant’s impact on enemies may be only one several effects ant tending that alters insect densities. To test variable impacts ants, mealybug enemy densities were monitored ant‐tended ant‐excluded vines two California vineyard regions. 2. Ant increased obscure mealybug,...
To understand ecological factors mediating the spread of insect-borne plant pathogens, vector species for these pathogens need to be identified. Grapevine leafroll disease is caused by a complex phylogenetically related closteroviruses, some which are transmitted insect vectors; however, specificities virus-vector interactions poorly understood thus far. Through biological assays and phylogenetic analyses, we studied role vector-pathogen specificity in transmission several grapevine...
Temperature-dependent fecundity and survival data was integrated into a matrix population model to describe relative Drosophila suzukii Matsumura (Diptera: Drosophilidae) increase age structure based on environmental conditions. This novel modification of the classic Leslie is presented as way examine how insect populations interact with environment, has application predictor density. For D. suzukii, we examined implications for pest pressure crops. As case studies, predictions in three...

Drosophila suzukii causes economic damage to berry and stone fruit worldwide. Laboratory-generated datasets were standardized combined on the basis of degree days (DD), using Gompertz Cauchy curves for survival reproduction. Eggs transitioned larvae at 20.3 DD; pupae 118.1 adults 200 DD. All are expected have died 610 Oviposition initiates 210 DD gradually increases a maximum 15 eggs per 410 subsequently decreases zero These data used as cohort-level population model. Laboratory under...
In recent years, there has been an increase in the adventive establishment and spread of parasitoid wasps outside their native range. However, lack taxonomic tools can hinder efficient screening field-collected samples to document range expansion parasitoids on continent-wide geographic scales. Here we report that Leptopilina japonica (Hymenoptera, Figitidae), a globally invasive fruit pest Drosophila suzukii (Diptera, Drosophilidae), is now widespread much North America despite not having...
Grapevine leafroll disease is caused by grapevine leafroll-associated viruses (GLRaVs). Within this virus complex, GLRaV-3 the predominant species in world. Several GLRaVs have been shown to be transmitted from vine mealybugs although a detailed characterization of transmission biology lacking. The introduction mealybug (Planococcus ficus) California and other regions world may result increasing incidence established GLRaVs. We studied characteristics mealybug. Our results indicate that...
The vine mealybug is a newly invasive pest that has spread throughout California's extensive grape-growing regions. Researchers are investigating new control tools to be used in combination with or as an alternative standard organophosphate insecticide controls. Insect growth regulators and nicotine-based insecticides provide good pesticides for use some vineyards. Ongoing studies on the augmentative release of natural enemies mating disruption also show promise, but commercial products not...
Summary Vine mealybug Planococcus ficus is an invasive pest of vineyards in many areas the world. In California, USA, it infests all plant subunits and has a spatial refuge from natural enemies under bark on roots. A temporal created when ants tending reduce efficacy enemies. Biological control vine only partially successful varies among California grape‐growing regions. To improve help determine appropriate for importation, effects weather regulation by two parasitoids, Anagyrus pseudococci...
The olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), is an invasive pest in California. Identifying environmental constraints that affect the geographic distribution and abundance of any insect fundamental to its effective management. California's Central Valley, where most commercial olives are grown, extremely hot during summer, with maximum daily temperatures consistently >35.0 degrees C. This study examined effects two diurnal temperature regimens (low 18.3 C, high 35.0...
Mealybugs have become increasingly important vineyard pests — a result of their direct damage to the vine, role in transmitting grapevine leafroll viruses, and costs for control. Numerous mealybug species are found vineyards, each has different biological traits that affect sustainable control options. We review natural enemies provide some clarification about current trends tactics needed directions future work.
