Article Synopsis
- The hibiscus bud weevil (HBW) poses a serious threat to tropical hibiscus in Florida since its invasion in 2017, making early detection vital.
- This study investigates the effectiveness of using pheromone lures, previously successful for other pests, in attracting HBW, testing various trap types, colors, and lure sizes.
- Results show yellow sticky traps with cranberry weevil lures are particularly effective for capturing HBW, but further research is needed to confirm the lure's overall efficiency.
In 2020, the invasive (Karny) was first detected in Florida, United States. In response to the implemented regulatory restrictions, we conducted laboratory experiments under containment conditions. Thrips larvae and adults were exposed to 32 products (conventional and biorational insecticides) either directly or indirectly.

Therefore, we selected 21 different insecticide and horticultural oil products to evaluate their effects on the reproductive rate, feeding, and oviposition behavior of the HBW. In laboratory experiments, significant mortality was observed in adult weevils exposed to diflubenzuron-treated hibiscus leaves and buds, and hibiscus buds treated with diflubenzuron contained the fewest number of eggs and feeding/oviposition holes.

Although the biologies of the congeneric boll weevil, Boheman 1843, and pepper weevil, Cano 1894 are well documented, no data are available regarding the biology of HBW.
