Evaluation of Encapsulated Parapheromonal Traps against Bactrocera Zonata (Saunders) under Laboratory Conditions

Abstract

The laboratory experiment was conducted to evaluate the efficacy of laboratory prepared encapsulated nanofiber fixed with methyl eugenol to attract peach fruitfly Bactrocera zonata (Saunders). Effect of wind velocity, time and distance on fly response towards encapsulated nanofibers was recorded. Various wind velocities (0.30, 0.65, 1.20, 1.70, and 2.45 m/sec) maintained through table fan were tested. Standard was made to release seven flies for each experimental trial. Temperature (29 °C ± 2) and relative humidity (64±4%) were maintained in the laboratory, RH Pearson’s Correlation was used to relate the independent variables i.e. distance, wind, and velocity against the attractiveness of traps towards fruit flies. This discovered the response of fruitflies with distance was moderately negative and highly significant (r -0.4090, p < 0.001); response of fruitflies with time was moderately negative and highly significant (r -0.5206, p < 0.001); relationship of flies with wind velocity was moderately negative and highly significant (r-0.3686, p < 0.001). Flies tend to take more time when either distance or wind velocity was increased.
