Abstract
The GWM is the key pest on honey bee colonies which feed on
honey bee combs and destroy the hive materials.In the present
investigations, the maximum electroantennogram response was
exhibited by female GWM against 5:95 ratio of binary blends of
nonanal and undecanal when compared to, 10:90, 15:85, 20:80,
40:60, 50:50, 70:30, 80:20, 90:10 and 5:95 ratios tested. Among
modified ratios of nonanal and undecanal @1:99, , 5:95, 7:93, 9:91,
12:88, 15:85, 100:0.00 and 0.00:100,the 7:93 (without solvent) and
5:95 (with solvent) ratios elicited maximum response in female GWM.
However, the efficacy of these blends in trapping female GWMs was far
too less when compared to live males and A.dorsata comb.GWMs were
attracted towards delta trap fixed with A.dorsata comb for more when
compared to A.cerana comb.Placing delta trap fitted with A.dorsata
comb on top cover of the A.cerana hive helped prevention the wax
moth infestation in A.cerana colonies.Out of two Bt products V-Bt
(commercial product) and HD-1(local Bt product), the highest larval
mortality with less comb damage was recorded in case of former. The
IPM practices comprising cultural (periodic cleaning), Mechanical
(oviposition trap installation) and chemical (lime Sulphur application)
methods when integrated helped in total protection of A.cerana bee
colonies from the attack of GWM up to three moths.
