Efficacy of Plinazolin and Selected Conventional Insecticides for Control of Pepper Weevil ( Anthonomus eugenii ) Adults: A Laboratory Bioassay

Pepper weevil, Anthonomus eugenii Cano (Coleoptera: Curculionidae), is one of the most economically troublesome pests of pepper production in the southern and south eastern USA. Management of this pest is challenging due to the internal larvae feeding habitat and development, limiting exposure to synthetic insecticides and reducing control efficacy. The effectiveness of available insecticides is further constrained by their non-target effects and the potential for resistance development. Here, we investigated the efficacy of the novel insecticide plinazolin (ISM-555) and selected conventional insecticides against adult pepper weevil under laboratory conditions. Adult mortality and incapacitation were assessed following insecticide exposure. Plinazolin and oxamyl (Vydate® C-LV) caused the highest adult mortality, while thiamethoxam (Actara®) also exhibited significant mortality compared with the untreated control. The results demonstrate the potential of plinazolin as an effective tool for pepper weevil management and provide baseline susceptibility data to facilitate monitoring of pepper weevil populations. Incorporating insecticides with different modes of action into rotation programs may improve control efficacy, and reduce the risk of resistance via integrated pest management (IPM) strategies for pepper weevil. © The Authors 2026

Towards the sustainable control of diamondback moth (Plutella xylostella L.) in cruciferous crops: current trends, resistance mechanisms, and future frontiers

Diamondback moth (DBM, Plutella xylostella L.) is one of the most damaging pests of cruciferous crops, causing significant economic losses in multiple agri-food production systems globally. The high reproductive potential of DBM, rapid adaptability to diverse ecological zones, and resistance to several synthetic insecticides destabilize their integrated pest management (IPM) efforts. Here, we critically synthesize the current knowledge on DBM research across key IPM thematic areas, including biocontrol, insecticide use, phytochemistry interactions, insect-associated microbiomes and insecticide resistance, as well as the impact of climate alterations. This review has emphasized the importance of evidence based on insecticide applications, which have encouraged the development of resistance and are not sustainable for use in insect population management. However, the availability of other options for biocontrol agents, such as parasitoids, predators, entomopathogens, and host-plant resistance, has also been significant and sustainable for the management of DBM population. Apart from this, the effects of climate fluctuation have increased the spread of DBM population, which has also necessitated the use of adaptive strategies for its management, such as advanced pest surveillance systems, genome editing, and climate resilient cropping systems for breeding resistance to the pest. Despite significant technological advancements, key research gaps remain, including a limited understanding of DBM interactions with phytopathogens, as well as the socio-economic and policy-related barriers that hinder the adoption of IPM. Hence, future goal for DBM control would be implementing robust, sustainable, eco-friendly, and technology-driven approaches to reduce the development of resistance to conventional insecticides and achieving maximum control effects. Future approaches should focus on multidisciplinary collaboration, farmer awareness, and policy support to improve sustainable DBM management. In conclusion, our review provides practical information for improving IPM strategies against DBM populations, ensuring food security, and developing long-term resilience of plant production systems under increasing ecological and climate change pressures.
