Abstract BACKGROUND Drosophila suzukii (Matsumura), spotted‐wing drosophila (SWD), is a major invasive pest of soft‐skinned fruits in North America and Europe. Although insecticides are currently the primary method SWD control, it imperative to develop alternative management approaches, such as behavioral control through use repellents attractants. This study explores repellent properties 2‐pentylfuran an oviposition deterrent on raspberries. RESULTS 2‐Pentylfuran was found be aversive...
Ethyl formate (EF) was evaluated as a potential alternative to methyl bromide (MB) for phytosanitary treatment of imported citrus fruit in the Republic Korea. Planococcus citri (Risso) (Hemiptera: Pseudococcidae), mealybug with known tolerance against EF and MB, used representative pest test efficacy two fumigants eggs. In nine commercial-scale refrigerated container (67.5 m3) trials using orange, lemon grapefruit, applied at currently approved dose (70 g·m-3 5°C 4 h, developed Aspidiotus...
Stable flies are one of the most detrimental arthropod pests to livestock. With changing climates and agronomic practices, they expand their roles as disease vectors well. Their painful bites reduce livestock productivity, annoy companion animals, interfere with human recreational activities. Current management technologies unable effectively control stable flies. The present study reports new results concerning contact, spatial repellency, toxicity a bio-based product, coconut fatty acid...
Abstract Morphology of antennal sensilla and their distribution were investigated in male female adults the parasitoid fly Gymnosoma rotundatum (Diptera: Tachinidae) using scanning electron microscopy (SEM). The overall length shape not different between males females from each other. Three basic types (sensilla basiconica, s. chaetica, coeloconica) identified both sexes, but with variations numbers along antennae. basiconica chaetica could be divided further into subtypes; three subtypes...
Two taxonomically similar Drosophila species, melanogaster and suzukii, are known to have distinct habitats: D. is mostly found near overripe fermented fruits, whereas suzukii attracted fresh fruits. Since chemical concentrations typically higher in fruits than hypothesized be of volatiles suzukii. Therefore, the preferences two flies were compared via Y-tube olfactometer assays electroantennogram (EAG) experiments using various 2-phenylethanol, ethanol, acetic acid. exhibited a preference...
Abstract BACKGROUND Bactrocera dorsalis , oriental fruit fly (OFF), is one of the most destructive agricultural pests. Although bait sprays can effectively control OFF resistance development has been a concern. We evaluated oviposition deterrent activity coconut free fatty acids (CFFA), mixture eight oil‐derived known to repel hematophagous insects and deter their feeding oviposition, against females. RESULTS In laboratory 72‐h two‐choice assays using guava‐juice infused‐agar as an...
Abstract Coconut free fatty acid (CFFA), a mixture of 8 acids derived from coconut oil, is an effective repellent and deterrent against broad array hematophagous insects. In this study, we evaluated the oviposition activity CFFA on spotted-wing drosophila (SWD; Drosophila suzukii), destructive invasive pest berries cherries, identified bioactive key-deterrent compounds. laboratory 2-choice tests, deterred SWD in dose-dependent manner with greatest reduction (99%) observed at 20-mg dose...
Abstract Mushroom fly, Lycoriella mali (Diptera: Sciaridae), is the primary pest in imported mushrooms. The amount of Tricholoma matsutake from China increases every fall when it harvested. When importing T. matsutake, disinfestation using methyl bromide (MB) or phosphine (PH 3 ) performed to prevent introduction L. . However, MB will be phased out due ozone-depletion, chronic toxicity workers, and residual issues. PH fumigation mushroom requires a long exposure time (24 h). In this study,...
Abstract Morphology of antennal sensilla and their distribution were investigated in adults Ooencyrtus nezarae , an egg parasitoid Riptortus pedestris using scanning electron microscopy. Male antennae was found to be significantly greater overall length than female antennae. The antenna O. composed the radicula, scape, pedicel, funicle clava both sexes, with seven types identified: sensillum trichodea; s. finger‐like; placoidea; chaetica; basiconica; coeloconica, campaniform. They occur...
Azuki bean beetle, Callosobruchus chinensis (L.) (Coleoptera: Bruchidae), is a field-to-storage pest of legumes and its females produce sex pheromone components with two isomers: (2Z,6E)-7-ethyl-3,11-dimethyl-2,6,10-dodecatrienal (2Z-homofarnesal) (2E,6E)-7-ethyl-3,11-dimethyl-2,6,10-dodecatrienal (2E-homofarnesal). Two-day-old virgin adults were treated different doses (0, 200, 300, 400, 500, 600 Gy) gamma radiation the effects on adult survivorship, fecundity, sterility, production...
Fumigation of fruits and vegetables during quarantine pre-shipment (QPS) treatment should be effective with a shorter fumigation time to minimize phytotoxicity. In this research study, time, 2 hours exposure which is than that the current commercial procedures using lower dose ethyl formate (EF) mixed phosphine (PH3) on strawberry was investigated. The reciprocal effect between EF PH3 against nymphs adult Myzus persicae (Sulzer) Tetranychus urticae (Koch) evaluated. addition, L(Ct)50 L(Ct)99...
Abstract Plant essential oils (EOs) exhibit an array of biological activities against insect pests. However, their negative influences on the pheromonal activity azuki bean beetle (ABB), Callosobruchus chinensis L. have not received research attentions. ABB is a field‐to‐storage pest legumes, and its female produces sex pheromone known as homofarnesal with two isomeric components: 2 E‐ Z –homofarnesal, (2 E ,6 )‐7‐ethyl‐3,11‐dimethyl‐2,6,10‐dodecatrienals...
Abstract Ooencyrtus nezarae (Hymenoptera: Encyrtidae) is an egg parasitoid of bean bug Riptortus pedestris (Hemiptera: Alydidae) which a major pest beans. Females O. are attracted to ( E )‐2‐hexenyl Z )‐3‐hexenoate EZ ), one the components aggregation pheromone R .

With an increase in the international trade of agricultural and non-agricultural products, there is possibility introducing hitchhiking insect pests such as Halyomorpha halys, which has been detected on imported vehicles machinery. Although methyl bromide (MB) provisionally used to control invasive pests, it classified a restricted chemical owing its potential deplete ozone layer pose health risks humans cases inadequate ventilation, well concerns regarding consumer safety. Therefore, this...
Abstract In this study, the morphology and distribution of antennal sensilla male female adults Plautia stali were investigated using scanning electron microscopy. both sexes, antennae P. composed a scape, two‐segmented pedicels (P1 P2) flagellomeres (F1 F2). There no differences in overall length shape between males females. Four basic types (s. trichodea, s. basiconica, chaetica coeloconica) identified each sex. Sensilla basiconica further divided into four two subtypes, respectively....
