Performance of different designed pheromone traps and their placement heights in capturing Leucinodes orbonalis Guenee (Lepidoptera: Pyralidae)

Abstract :

The present experiment was conducted to evaluate efficacy of different designed pheromone traps placed at different heights to control brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis male moth caught under field conditions during October 2019 to April 2020. Three types trap such as BARI water trap, Bangalore open water trap and Indian funnel trap were used. The traps were set at 0.5 m, 1.0 m and 1.5 m above the ground level following randomized complete block design (RCBD) with 3 replications. Among the pheromone traps significantly the highest (169.0) number of male moths were caught by Bangalore open trap with an average 11.27 moths/5day when the traps were installed below the plant canopy level (0.5m).  On the contrary, the lowest (19.67) moths were caught in Indian funnel trap with an average 1.31 moths/5day while installed at above the plant canopy level (1.5m). Consequently, the lowest infested shoot (5.83%) fruits (12.48 %) and healthy fruits (72.12%) were recorded in Bangalore open trap when the traps were installed below plant the canopy level. On the contrary, the highest infested shoots (19.10%), fruits (37.80%) and healthy fruits (89.99%) were recorded in Indian funnel trap when the traps were installed above plant canopy level.
