To evaluate the efficacy of termite baiting in suppressing field population of fungus-growing termites, a durable termite bait with hexaflumuron was evenly installed in a one-hectare forest area dominated by a fungus-growing termite, Odontotermes formosanus (Shiraki). Monthly monitoring of termite foraging activity on baits and wood stakes was conducted for 4 years to quantify efficacy of baits. To examine whether the hexaflumuron led to colony death, pesticides in fungus gardens of active and deceased nests were quantified using a LC-QTOF/MS. RESULTS: After baiting, 50% and 90% of baits were fed upon 10 and 24 months, respectively. After 2 years of baiting, the monthly number of wood stakes occupied by termites was reduced from 34.7 ± 1.8 to 17.6 ± 2.5 (?49.1%), and the number of wood stakes consumed was reduced from 17.7 ± 0.8 to 13.3 ± 1.2 (?25.7%). Hexaflumuron was detected in deceased colonies, including five of six fungus gardens and the fungal tissue of Xyleria grown on fungus gardens, with a concentration of 0.31–20.11 mg kg?1 dry weight. CONCLUSION: This study demonstrated that durable hexaflumuron baits consumed by fungus-growing termites were further incorporated into fungus gardens, resulted in colony elimination and negative area-population effects, supporting that durable hexaflumuron baits are effective in suppressing field populations of fungus-growing termites. ? 2021 Society of Chemical Industry. ? 2021 Society of Chemical Industry. |
