ABSTRACT This study investigates the bioactivities of C. longa extracts and parasitoid A. calandrae against maize weevil, a significant pest in tropical subtropical regions. The experiments were conducted completely randomized design with five replications six concentrations an incubator at 27 ± 3°C 65 5% R.H. photoperiod 12:12 h (L:D). found that , except higher (2.5 3%), had no effect on settlement adults treated grains. Corn kernels aqueous 0.5, 1, 1.5, 2% showed development differences compared to untreated control. No (P > 0.05) when was offered Sitophilus zeamais for parasitization grains 2, 2.5% extracts. evaluated reduced populations S. by 20.06, 26.87, 35.19, 41.36, 52.97 62.54% whereas; treating 2.5 3% combination release pairs parasitoids per treatment population 64.24, 66.42, 72.71, 80.87, 86.30 90.64% respectively. appropriate can effectively manage weevil grain storages as alternative chemical insecticides.

Seasonal phenology and host plant use by Leptopilina japonica (Hymenoptera: Figitidae) attacking Drosophila (Diptera: Drosophilidae) in managed and unmanaged habitats, determined using a modified sticky trap collection method

Journal of Economic Entomology, Journal Year: 2025, Volume and Issue: unknown

Published: April 16, 2025

Abstract Biological control of Drosophila suzukii may be enhanced through adventive populations the figitid parasitoid Leptopilina japonica (Novković & Kimura) (Hymenoptera: Figitidae). This insect has expanded its range considerably but we have limited understanding phenology, wild host plant associations, and response to fruit crop management this parasitoid. To address these gaps, samples were collected in managed habitats across southern Michigan, placed on metal mesh a plastic container until insects emerged, when they captured identified. We selected yellow sticky traps based experiments compare trap types for capture D. L. japonica. Weekly checking resulted 2,108 2022 2023 yielding 7,598 specimens. Wasp detection started mid-July increased steadily mid-September, with activity declining into October. emerged from multiple species, highest yield both years blackberry (Rubus spp.), American black elderberry (Sambucus canadensis), pokeweed (Phytolacca americana) fruit. was much more abundant unmanaged organic blueberry plantings than commercial fields during berry ripening, sharp increase after pesticide applications ended. The methods described here facilitate widespread sampling parasitoids without needing daily collection insects. Our results highlight an updated method showing that established production regions persisting (Diptera: Drosophilidae) larvae berries plants ripen growing season.

Ganaspis kimorum (Hymenoptera: Figitidae), a promising parasitoid for biological control of Drosophila suzukii (Diptera: Drosophilidae)

Journal of Integrated Pest Management, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 1, 2024

Abstract Ganaspis Foerster includes several cryptic species that are important larval parasitoids of the invasive pest Drosophila suzukii (Matsumura), spotted-wing drosophila (SWD). suzukii, native to Asia, was first discovered in 2008 North America and Europe, becoming a devastating soft-skinned fruit crops. Biological control could be among safest, most environmentally benign, cost-effective methods for long-term landscape-level management this pest. Foreign exploration East Asia major D. parasitoids. One them initially described as brasiliensis (Ihering) consisted 2 genetic groups (G1 G3). The now recognized different species, kimorum Buffington lupini Buffington. more host-specific G. selected approved field release United States 2021 has been widely released since 2022. Here, we provide comprehensive overview parasitoid’s taxonomy, current known distribution, biology, ecology, mass-rearing methods, biological potential.
