Fruitfly prediction model by using male annihilation technique with different types of cost effective traps in guava orchards under three districts of Punjab

Abstract : 

Fruit fly, Bactrocera zonata and Bactrocera dorsalis (Diptera: Tephritidae) is a major pest of fruits especially guava and trade barrier of Pakistani fruits in foreign markets. Mass trapping of this pest by suitable selection of trap is necessary for its management by MAT (Male Annihilation Technique). Experiment was conducted in three different guava producing districts of Punjab i.e. Faisalabad, Sargodha, Toba Tek Singh. Three locations in each district were selected for the experiment with each 3 acres area. Three types of traps were used i.e. RT (Round Trap), JT (Jar Trap) and PBT (Pet Bottle Trap) with 6 traps/acre. Multiple linear regression equations and correlation were computed on the mean population data in all the traps for each year. Results showed that April, May and June (standard weeks 13-23) are peak activity periods of fruitfly in all the districts. Temperature exerted highly significant and positive impact, humidity had non-significant and positive while rainfall was non-significant and negative impact on per unit population fluctuation. PB trap had significant and positive correlation in all three districts during 2016. Maximum impact of temperature was 43.5 and 42.8% at Faisalabad, relative humidity 26.2 and 22.2% at Sargodha, Faisalabad and rainfall 26.3 and 15.1 % at Sargodha computed during 2015 and 2016, respectively. Pet bottle trap gave maximum adult catches at all districts with minimum cost 13.30 $/ha in a year. which is suitable for farmer’s community to be used in prediction model
