Methyl eugenol trapping

The parapheromone traps are excellent tool in reducing the population of fruit flies in snake gourd ecosystem. In farmer‟s situation, due to lack of awareness, availability and knowledge on its mechanism of trapping all paves way to move towards the spraying of insecticides. Considering these key limitations, this present investigation was framed to develop locally available, cost effective trap designs for the efficient eco-friendly management of fruit flies in snake gourd ecosystem.

In the present investigation, twelve types of lure traps with different combinations were evaluated for monitoring the fruit fly population for two seasons i.e. during 2017-2018 and 2018-2019. The studies revealed that, there was a significant difference recorded among all the twelve traps in both seasons. For 2017-2018 season, in commercial traps, Green victory methyl eugenol (ME) fruit fly trap showed the best performance in capturing adult fruit fly population throughout the cropping period with catch of 479.33 fruit flies/trap.

The species diversity of Dacinae fruit flies (Bactrocera spp.) was monitored in guava growing areas in various districts of western Uttar Pradesh, India, over a 12 months period (October, 2017- September, 2018). Samples of fruit flies were collected by using methyl eugenol lure traps and infested guava fruits collected from the farmer’s orchards in fruiting season. Three species of fruit flies recorded were, Bactrocera correcta, B. dorsalis and B. zonata. In general, proportionately higher population of B. zonata was recorded form various places surveyed.
