Article Abstract
The Smith (Lepidoptera: Noctuidae) is a globally invasive pest, and its management is primarily dependent on chemical pesticides, which has spurred the need for eco-friendly control strategies. The push-pull strategy, an environmentally friendly pest management approach, has shown promise in controlling . In this study, using a combination of adult oviposition, larval feeding, and electrophysiological tests, we confirmed the repellent properties of coriander and its volatiles. Gas chromatography-mass spectrometry analysis of coriander volatiles revealed -2-decenal as the major repellent compound. Furthermore, SfruOBP13 was identified as one of the main odorant-binding proteins that detects -2-decenal in the , providing a molecular basis for the insect's perception of this volatile. These findings lay the groundwork for developing behavior-based pest control strategies, offering valuable insights for sustainable management using plant-derived semiochemicals.

The ability of parasitoid wasps to precisely locate hosts in complex environments is a key factor in suppressing pest populations. Chemical communication plays an essential role in mediating insect behaviors such as locating food sources, hosts, and mates. Odorant receptors (ORs) are the key connection between external odors and olfactory nerves.

The Citrus Under Protective Screen is a novel production system implemented to grow citrus free of huanglongbing disease vectored by Asian citrus psyllid, Diaphorina citri. Other significant pests such as mites, scales, thrips, mealybugs, and leafminers, as well as parasitoids and small predators, have been identified from Citrus Under Protective Screen and require management.

Ionizing radiation is widely used in insect sterilization for pest control using the Sterile Insect Technique, which consists of the mass rearing of insects and their irradiation with gamma rays to release them in target areas where they will mate with wild females. However, there is a concern and controversy about the nuclear origin applied in this technique. One alternative for sterilization is the use of X-rays, which do not have a nuclear origin, are easier to operate, and do not generate radioactive waste.

Evaluating the olfactory preferences of emerging insect pests is critical to develop monitoring tools and improve early detection and management strategies. Here the chemical ecology and olfactory preferences of the allium leafminer Phytomyza gymnostoma Loew (Diptera: Agromyzidae), an invasive pest in North America affecting allium crops such as leeks and onions, were investigated. Three bioassay methods were assessed under laboratory conditions: wind tunnel, Y-tube olfactometer, and arena bioassay.

Background: Rapid advances in generative artificial intelligence (AI) are accelerating the process of pesticide development. However, transfer learning-based de novo design focuses on generating molecules that are highly similar to existing inhibitors, which may limit the exploration of novel scaffolds and thereby constrain innovative breakthroughs in pesticide development.
Results: This study proposes a new strategy for fungicide design using antibiotics.
