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 markets, frozen berries, export programs have been impacted due zero tolerance for infestation. As control rely heavily on insecticides, exceedance maximum residue levels (MRLs) resulted in crop rejections. The impact particularly severe organic operations, mainly limited availability effective insecticides. Integrated management (IPM) could significantly reduce chemical inputs but would require substantial changes horticultural practices. This review evaluates most promising methods studied part an IPM strategy against across world. For each considered techniques, effectiveness, impact, sustainability, stage development are discussed.

Insects, Год журнала: 2025, Номер 16(3), С. 253 - 253

Опубликована: Март 1, 2025

Drosophila suzukii is an invasive pest that poses a significant threat to fruit crops worldwide, leading considerable agricultural losses and economic damage. Unlike chemical control measures against D. suzukii, integrating insect-proof nets within IPM framework offers more sustainable solution. This study evaluates the efficacy of nine commercial protective this pest, focusing on determining optimal hole dimensions based effects airflow velocity, temperature, morphometry net performance. To simulate field conditions in laboratory, we developed tubular device divided into three chambers with tested placed between two, incorporating fan generate thermo-anemometer. Our results confirm higher air velocities elevated temperatures reduce efficacy. Additionally, morphometric analyses lab-reared flies revealed sexual dimorphism strong temperature–size relationship, reared at lower being consistently larger, aspect also affects effectiveness. These findings highlight importance considering both abiotic factors morphology when evaluating screens, challenging assumption exclusion remains constant. Some proved completely effective SWD, supporting their use as preventive measure programs.

Monitoring pesticide resistance is essential for effective and sustainable agricultural practices. Bioassays are the basis pesticide-resistance testing, but devising a reliable reproducible method can be challenging because these tests carried out on living organisms. Here, we investigated five critical parameters how they affected evaluation of to organophosphate phosmet or pyrethroid lambda-cyhalothrin using tarsal-contact protocol Drosophila suzukii, worldwide invasive pest. Three were related insect biology: (i) sex, (ii) age imago (adult stage) (iii) genetic diversity tested population. The two remaining linked experimental setup: (iv) number individuals per dose (v) duration exposure active ingredient. Results showed that response insecticide differed depending males being twice as susceptible females. Age principally young females' susceptibility phosmet, 0-24 hour-old flies 24-48 72-96 Genetic had no observable effect levels. precision accuracy median lethal (LD50) greatly by with threshold effect. Finally, optimal ingredient was 24 h, found an underestimation mortality when assessed between 1 5 h after lambda-cyhalothrin. None main known point mutations para sodium channel gene associated knockdown observed. Our study demonstrates importance calibrating various bioassay develop method. It also provides valuable transferable monitoring D. suzukii worldwide.

The Gram-Positive Bacterium Leuconostoc pseudomesenteroides Shows Insecticidal Activity against Drosophilid and Aphid Pests

Insects, Год журнала: 2020, Номер 11(8), С. 471 - 471

Опубликована: Июль 25, 2020

Insect pests reduce global crop yields by up to 20%, but the most effective control measures are currently based on environmentally hazardous chemical pesticides. An alternative, ecologically beneficial pest-management strategy involves use of microbial pathogens (or active compounds and extracts derived from them) that naturally target selected insect pests. A novel strain bacterium Leuconostoc pseudomesenteroides showed promising activity in our preliminary tests. Here, we investigated its effects more detail, focusing drosophilid aphid testing survival two species representing family Drosophilidae (Drosophila suzukii D. melanogaster) one Aphididae (Acyrthosiphon pisum). We used oral septic infection models administer living bacteria or cell-free adult flies nymphs. found with significantly reduced models, whereas administration had a significant effect only aphids. These results confirm L. has potential as new biocontrol agent for sustainable pest management.

Abstract Nitrogen (N) is a key nutrient required by all living organisms for growth and development, but limiting resource many organisms. Organisms that feed on material with low N content, such as wood, might be particularly prone to limitation. In this study, we investigated the degree which xylophagous larvae of stag beetle Ceruchus piceus (Weber) use associations N-fixing bacteria acquire N. We paired acetylene reduction assays cavity ring-down absorption spectroscopy (ARACAS) 15N2 incubations characterize rates fixation within C. piceus. Not only did detect significant activity larvae, calculated rate was substantially higher than most previous reports in insects. While taking these measurements, discovered can decline rapidly lab setting. Consequently, our results demonstrate studies, commonly keep insects long periods time prior during measurement, may have systematically under-reported This suggests within-insect contribute more insect nutrition ecosystem-scale budgets previously thought.
