TAILIEUCHUNG - Studies on species diversity of fruit flies and evaluation of pheromone lure longevity in guava (Psidium guajava L.) cv. Allahabad Safeda

Studies were carried out to determine the species diversity of fruit flies and pheromone lure longivity was evaluated in guava orchard cv. Allahabad safeda at Fruit Research Station Sangareddy. Randomized block design was followed for the experiment with 8 treatments and 3 replications. Initially all the traps were loaded with pheromone lure, later the lure was changed from the traps at 30, 35, 40, 45, 50, 55 and 60 days interval. Various parameters such as species diversity of fruit flies, number of fruit fly catches, number of healthy and damaged fruits on the tree, weather data were recorded. Three species of fruit flies viz., Bactrocera correcta, Bactrocera zonata and Gastrozona fasciventris were identified. The number of fruit fly catches were highest in T1 when the lure was changed at 30 days interval, with lowest number of damaged fruits and highest number of healthy fruits against the tree without traps ., T8 (Control). When the weather parameters were correlated with number of fruit fly catches and age of the lure it was found that there was positive correlation with maximum temperature, minimum temperature, relative humidity I & II however there was no correlation with rainfall and negative correlation with wind velocity. Pheromone longevity in the traps was for 30 days. | Studies on species diversity of fruit flies and evaluation of pheromone lure longevity in guava (Psidium guajava L.) cv. Allahabad Safeda
