According to the Entomological Society of America's (ESA) recent position statement, invasive insects incur control costs over $2.5 billion and cause economic damages crops, lawns, forests, pastures totaling $18 per year ("The Not-So-Hidden Dangers Invasive Species" 2018). The threat crop pests food security continues be driven by complex dynamics human movements, global trade activities, climate change, changing agricultural practices. Chemical insecticides have been central protection against insects. However, a growing demand for reduced chemical use due environmental health concerns in addition pesticide resistance issues are fueling interests innovative approaches manage pests. For decades, role microbes pest management has largely confined using entomopathogens, with only handful microbial species being developed into bioinsecticides. paradigm is shifting owing advent high-throughput sequencing, functional omics, gene editing technologies, which greatly accelerate discovery, as well better understanding functions communities across different habitats. There also overwhelming evidence that symbiotic play pivotal roles shaping various insect traits. collection associated given environment (both biotic abiotic) their collective genetic materials termed microbiome.

Explorative Data Analysis of Drosophila suzukii Trap Catches from a Seven-Year Monitoring Program in Southwest Germany

Insects, Год журнала: 2018, Номер 9(4), С. 125 - 125

Опубликована: Сен. 24, 2018

Over the last decade, Drosophila suzukii Matsumura, an invasive pest of soft-skinned fruits, gradually established itself in Europe, often resulting significant economic losses. In 2011, when D. was first described for Germany, Julius Kühn Institut (JKI) started a monitoring program southwest Germany to study occurrence and activity fly. Capture data from late 2011–early 2018 100 traps were analyzed effect weather immediate habitat on trap captures at different times year. We identified five phases annual population development cycle suzukii. found that mild winter 2013/2014 helped thorough establishment Germany. Habitat types vicinity local conditions had strong influence captures. Forest borders hedges provide adequate overwintering shelter flies. Trap forests generally higher than those vineyards orchards, even during fruiting seasons. Summer capture rates correlated with number heat days precipitation. also discuss briefly limitations using as representative fly density field.

Behavioral manipulation of Drosophila suzukii for pest control: high attraction to yeast enhances insecticide efficacy when applied on leaves

Pest Management Science, Год журнала: 2021, Номер 78(3), С. 896 - 904

Опубликована: Окт. 30, 2021

The invasive pest, Drosophila suzukii attacks fresh soft-skinned fruit. Broad-spectrum insecticides are implemented for control but there is a need to reduce environmental risks and insecticide residues on fruits. Hanseniaspora uvarum yeast frequently found ripe fruits associated with D. suzukii. We aim exploit the ecological association attraction of H. by developing an attract-and-kill strategy, spray-application canopy not therefore investigated attraction, egg-laying mortality when exposed insecticidal yeast-based formulations.Hanseniaspora strongly attracted applied leaves grapevine, Vitis vinifera. Notably, this attractiveness was competitive grape berries that were susceptible infestation. Moreover, adding enhanced efficacy formulations against Flies treated yeast-insecticide showed higher laid lower number eggs compared flies alone. In wind tunnel, all treatments containing alone or in combination insecticides, caused similar upwind flight landing at odor source, which provides evidence addition did yeast.Hanseniaspora can be used manipulate behavior attracting formulations. Yeast improves effectiveness, suggesting sprays covering only, could fruit without compromising management efficacy.

Screening of 25 different natural crop protection products against Drosophila suzukii

Journal of Applied Entomology, Год журнала: 2018, Номер 142(6), С. 563 - 577

Опубликована: Апрель 11, 2018

Abstract Drosophila suzukii is a major pest of soft‐skinned fruits, and insecticides are often used to prevent fruit damage caused by oviposition. As D. produces many generations per year, repeated insecticide applications required. Furthermore, attacks ripening ripe fruits shortly before harvest. Therefore, the use synthetic limited long pre‐harvest intervals maximum residue limits. To be able offer producers immediate sustainable solutions, we tested 25 natural crop protection products with three different application methods in laboratory screening. We show that method an important factor for efficacy products. Of six insecticides, only Spinosad was toxic reduced oviposition on treated blueberries. The oil had no control effect based entomopathogenic fungi Bacillus thuringiensis rather enhanced Mineral (Kaolin, Ca CO 3 , Ca( OH ) 2 clinoptilolith) applied as spray solutions were not toxic, but significantly provide first study which have been compare numerous, commercially available, modes action against adult .

Spotted Wing Drosophila in Sweet Cherry Orchards in Relation to Forest Characteristics, Bycatch, and Resource Availability

Insects, Год журнала: 2018, Номер 9(3), С. 118 - 118

Опубликована: Сен. 13, 2018

Forest vegetation is essential for the population development of spotted wing drosophila (SWD). Yet, little known how structure surrounding forest areas influence abundance SWD within orchards. In this work, we use data from a field trial at five sites in Switzerland to analyse relationship between extent area, its edge density, and distance orchard with occurrence sweet cherry orchards Bayesian hierarchical model. Availability cherries bycatch were also included model account effects resource availability trap attractiveness, respectively. For all main their interactions, accounted potential temporal changes by adding interactions time. We found that closer an was forest, more trapped orchard. However, interaction proximity area caused disproportionate decrease catches. Also, variables, catches other drosophilid flies affected catches, but relation changed course experiment. The findings imply reducing crop fields requires not only consideration processes outside host field, temporally changing relationships factors.

Polyols are commonly used in food and medicines as sweeteners preservatives but may also have insecticidal properties against some species of Diptera. Here we compared the activity feeding response glycerol propylene glycol (PG) on two tephritids: Anastrephaludens Anastrephaobliqua, drosophilid Drosophilasuzukii. First, flies were exposed to solutions 50% sucrose polyols at concentrations 1.67 M, 2.78 M 4.18 for 24 h then observed intervals a period three days. Both elicited strong regurgitation behavior killed them. Regurgitation apparently reduced flies' body weight, this was particularly apparent insects that fed PG solutions. A high percentage individuals perished after 72 hours. The number proboscis extensions, which is associated with preference, lower + mixtures than solution. Glycerol had effect Anastrepha spp. very little D.suzukii. Finally, elevated mortality confirmed A.ludens treated 1.0⁻2.78 erythritol plus sucrose.

Agricultural-Grade Apple Cider Vinegar Is Remarkably Attractive to Drosophila suzukii (Diptera: Drosophiliadae) in Mexico

Insects, Год журнала: 2020, Номер 11(7), С. 448 - 448

Опубликована: Июль 15, 2020

Due to its availability and low cost, apple cider vinegar (ACV) is a frequently used as an attractant for monitoring the invasive spotted wing drosophila, Drosophila suzukii. In laboratory cage experiments, attraction of ACV alone was compared with in mixtures different concentrations acetic acid, propionic hydrolyzed proteins, synthetic fruit flavors (strawberry, blackberry apple) addition nectars (grape, pineapple apple). The 5% nectar significantly increased fly captures, whereas other combinations were similar or less attractive than alone. Apple flavored not flies. Captures did vary among brands commonly sold Mexico, except one poorly-performing brand, but cup traps baited agricultural-grade unfit human consumption captured approximately two-fold more flies commercial attractants Suzukii Trap, Trap Max experiments. Field trials performed polytunnels planted raspberry crops Mexico resulted ten-fold higher numbers D. suzukii by Droskidrink (a mixture ACV, red wine sugar), edible grade species selectivity agricultural that tested. Agricultural-grade also female male field trials. We conclude remarkably high attractiveness cost makes it useful tool populations berry crops.
