| contents | Predatory effectiveness of the copepod Mesocyclops thermocyclopoides on Aedes aegypti larvae: insights for biological control. Duong, Cuong V Ta, Le-Minh Pham, Thanh Thuy Thi Vu, Ngoc Anh Dinh, Khuong V Animals Aedes Copepoda Predatory Behavior Larva Pest Control, Biological Mosquito Control Copepods of the genus Mesocyclops are promising biological control agents against Aedes aegypti larvae, the primary vectors of dengue in tropical regions. However, the influence of prey density and environmental factors on the predatory efficiency of Mesocyclops copepods against Ae. aegypti larvae remains poorly understood. To address this knowledge gap, we investigated the predatory capacity of the tropical freshwater copepod predator Mesocyclops thermocyclopoides across 12 combinations of four larval instars (L1-L4) under three water volumes (5, 10, and 20 mL). Functional response (FRs) models were employed to quantify predation rates as a function of prey density and water volumes. Predation is significantly influenced by both larval stage and water volume, particularly, higher predation rates occurred in early-stage larvae (L1-L2) in medium volumes (10 mL). The predator consistently exhibited FRs type II among all water volumes. High predatory efficiency was observed to correspond with high attack rates and low handling times. While early instars were more frequently killed in absolute number, the probability of surplus killing was significantly higher for later instars. These findings demonstrate that M. thermocyclopoides is an effective predator of Ae. aegypti larvae and highlight its potential as a natural biological control agent for mosquito-borne diseases. © 2026 Society of Chemical Industry. |
