ABSTRACT
The Bactrocera species which belong family Tephritidae commonly called as fruit flies, according to inhabitants they live in tropical and subtropical areas of the world. The fruit flies are the pest of several economical important fruits of world. The Bactrocera dorsalis (handle) complex fruit fly according to morphology, physiology and genetically. It is very serious pest of many fruits in the overall world; such as guava, apricots, Sapodillas etc. this species is voracious for the mango in whole world mostly; means the favorable host of delicious mango. During current study observe the ecological margins and its habitats, host effects on the occurrence of this decisive pest. This study was steered in district Naushahro feroze of Sindh Pakistan during mango season of 2014-2015. Actually, this district is well known according to citreous fruity land Pakistan where lot of citreous fruits cultivated. The selected 2 hectors orchards per of mango field in per-taluka (five talukas) with different varieties of mango; 10 traps and lures were hanged in (2 hector) trees. Volatile chemical (Methyl eugenol) in plastic traps by cotton water-logged. Weekly traps were checked and changed almost we find out 10-12 replications of flies. According to statically examination we have got results 98.6% Bactrocera dorsalis flies caches in lures and traps, maximum number of flies cached during July (8285, 11693, respectively) at the peak mango season while minimum number of flies caches during month of September (959, 1100, respectively) during successive season of mango in 2014-2015. The mean value of Bactrocera species were found with figure of 207.1. Total fruit flies significant values (f = 41.36, p<0.05) with total mean population of fruit flies (15.62±137.4) in different talukas during two seasons of mango. The climatic parameter shows the relationship with occurrence of Bactrocera dorsalis species with mostly positive impact, temperature (r=0.66, r= 0.77 respectively), rainfall (r = -0. 45, r= 0.82 respectively), Humidity (r=- 0.37, r = - 0.024, respectively) and wind velocity (r=-0.62, r= -0.419, respectively). Current status of fruit flies shows that all the factors of ecology, directly are indirectly impact on the progress physically and reproductively enhance the growth of Bactrocera dorsalis. These ecological correlations play key role in development of pest.
