“…In this study, we used a Y-tube olfactory meter which included in its design, most of the critical elements necessary for determining the mosquito-repellent activity of citronellal in vitro. The Y-tube olfactory meter is a widely accepted approach for studying odor detection in insects 69 – 74 . Our results confirmed that citronellal volatiles repelled A. gambiae s.s. and that its efficiency exhibited significant dose response effects in the defined experimental treatments.…”

Anopheles gambiae s.s. is a key vector of Plasmodium parasites. Repellents, which may be a promising alternative to pesticides used to control malaria mosquitoes. Although citronellal is a known mosquito repellent, its repellency characteristics are largely unknown. Determining the specific odorant-binding proteins (OBPs) and odorant receptors (ORs) that detect and transfer the citronellal molecule in A. gambiae s.s. will help to define the mode of action of this compound. In this research, we assessed the repellent activity of citronellal in A. gambiae s.s. using a Y-tube olfactory meter, screened candidate citronellal-binding OBPs and ORs using reverse molecular docking, clarified the binding properties of predicted proteins for citronellal using fluorescence competition binding assay. Results showed that citronellal had a dosage effect on repelling A. gambiae s.s.. The 50% repellent rate was determined to be 4.02 nmol. Results of simulated molecular docking showed that the only proteins that bound tightly with citronellal were AgamOBP4 and AgamORC7. Fluorescence competitive binding assays confirmed the simulations. This research determined that citronellal was captured by AgamOBP4 and transmitted to AgamORC7 in A. gambiae s.s.. Our study will be beneficial in the further understanding the repellent mechanism of citronellal against A. gambiae s.s..

“…Soybean seeds (var. Pioneer P49T97R-SA2P) were planted into pots (15.24 cm diameter and 14.22 cm depth) in Sunshine potting mixture #8 (SunGro Horticulture, Bellevue, WA, USA) and grown in an incubator free of pests and pesticides at (26 ± 2 °C and 55 ± 5% RH) [ 30 ]. Plants were watered daily (~200 mL per pot) and fertilized according to the manufacturer’s instructions (Scotts-Sierra Horticultural Product Company, Marysville, OH, USA) once a week until use for M. cribraria rearing.…”

“…A colony of adult kudzu bugs was established by collecting insects from kudzu, Pueraria montana (Lour) Merr., in Auburn, AL (32.5934° N, 85.4952° W) from late March to May 2021. They were reared in ventilated plastic cages (30 cm × 30 cm × 30 cm) (BugDorm-2, Megaview Science Education Services Co., Ltd., Taichung, Taiwan) at 25 ± 1°C, 14:10 h (L:D), and 75 ± 5% RH [ 30 ] in a growth chamber (Percival, Perry, IA, USA.) and provided organic green beans and a vegetative-stage (V2-V3) soybean plant, approximately 18 to 27 cm tall, that could easily fit into the cage.…”

“…Kudzu bugs, Megacopta cribraria Fabricius (Hemiptera: Plataspidae), and their egg parasitoids can be used as a model host-parasitoid system to evaluate the outcome of interspecific competition. Two parasitoids, a generalist Ooencyrtus nezarae Ishii (Hymenoptera: Encyrtidae), and a specialist Paratelenomus saccharalis Dodd (Hymenoptera: Platygastridae), co-occur and parasitize kudzu bug eggs in Southeast Asia and the southeastern United States [ 28 , 29 , 30 , 31 ]. Immatures of both parasitoids feed and develop inside of the host eggs [ 32 , 33 ].…”

The present study investigated egg parasitoid interspecific interactions between a generalist, Ooencyrtus nezarae Ishii (Hymenoptera: Encyrtidae) and a specialist, Paratelenomus saccharalis Dodd (Hymenoptera: Platygastridae) in a laboratory setting using kudzu bug (Megacopta cribraria Fabricius, (Hemiptera: Plataspidae)) eggs as their shared host. Three experiments were conducted to evaluate the emergence of wasps from parasitized hosts after the simultaneous and sequential release of wasps, monitor aggressive behavior of P. saccharalis, and quantify intraguild predation of O. nezarae larvae on heterospecific P. saccharalis larvae. Results showed that total host egg parasitism was higher when both wasps were released simultaneously than if wasps were released sequentially. Ooencyrtus nezarae produced more total offspring than P. saccharalis in all sequential/simultaneous treatments but produced male offspring in most cases. In the aggressive behavioral experiment, specialist, P. saccharalis used head butting to fight O. nezarae, but no other aggressions were observed. In an experiment examining intraguild predation, O. nezarae was able to develop in host eggs parasitized by P. saccharalis four days earlier, acting as a superior larval competitor. These findings shed light on the potential interspecific interactions between O. nezarae and P. saccharalis, which may determine their relative abundance and influence their compatibility in kudzu bug biological control programs.
