Abstract:
[Aim] To identify the best trap type, and
position relative to beehives, for trapping wasps. [Methods] Five types of traps were evaluated;
500 mL conical bottles (Trap 1), 300 mL Nongfu Spring juice bottles (Trap 2),
500 mL Coca-Cola bottles (Trap 3), 1.25 L Coca-Cola bottles (Trap 4) and 4.5 L
Wahaha Pure Water bottles (Trap 5). Each trap type was evaluated in five
different situations relative to beehives; 0.3 m from an elevated beehive (H-D0.3),
1 m from an elevated beehive (H-D1), 0.3 m from a ground level beehive
(L-D0.3), 1 m from a ground level beehive (L-D1), and hanging on a branch 2 m
from a beehive (T-D2). Traps were baited with 50% sucrose solution and trapping
was conducted over 14 days with three replicates per treatment. [Results] Significantly more wasps were caught by
trap 1 than by traps 2, 3, and 4 (P < 0.05) in all five
locations over the first 9 days, and at H-D1 on day 14. Trap 1 also caught
slightly more wasps than trap 5, however this difference was not significant (P > 0.05). Comparing the
number of wasps caught at different positions over the first 9 days, and by
trap 1 on day 14, the
best position was H-D1, where significantly more wasps were captured than at
the other three positions (P < 0.05). There was no significant
difference in the number of wasps caught between H-D0.3, L-D0.3 and L-D1 (P
> 0.05). Considering both trap type and situation, placing conical
bottle traps 1 m away from elevated beehives achieved the best results (P
< 0.05). [Conclusion] Placing
conical bottle traps 1 m away from elevated beehives was the best overall wasp
trapping regime and is recommended as an efficient, environmentally-friendly,
integrated, method of wasp control.
