Abstract:
The experiment was conducted during the period from November 2013 to April
2014 at the research farm of Sher-e-Bangla Agricultural University (SAU), Dhaka
to study the effect of pheromone traps and trapping locations on capturing male
moth of brinjal shoot and fruit borer and fruit yield of brinjal. Brinjal variety
Shingnath was used as the test crop of this experiment. Four types of pheromone
traps were placed at two locations in a two factor Randomized Complete Block
Design (RCBD) with three replications. The pheromone traps types were T1:
Funnel type trap; T2: GME trap; T3: BARI trap I; T4: BARI trap II and two
locations were L1: Canopy level and L2: Upper canopy level. Among differnt traps
types GME trap was more effective for catching male moth (6.43 male caught per
trap per day), gave the lowest shoot and fruit infestation (5.21%, 5.82%, 6.73%
and 4.52%, 5.92%, 6.69%, respectively) at early, mid and late fruiting stages and
produced more insect free brinjal fruits (45.36 t/ha). Pheromone traps located at
canopy level showed better performance for catching male moth (5.24 male
caught per trap per day), and lowest shoot and fruit infestation (8.07%, 10.78,
11.94% and 9.44%, 11.81%, 14.13%, respectively) at different fruiting stages and
produced more insect free brinjal fruits (42.92 t/ha). GME traps located at canopy
level caught the highest number of male moths, reduced maximum percentage of
shoot and fruit infestation and gave more yield of fruits. GME trap and located at
canopy position was more effective for the management of brinjal shoot and fruit
borer.
