Biodiversity of Aphidiinae species (Braconidae: Hymenoptera) in Sargodha region with particular reference to citrus orchards

Abstract :

In nature, different Aphidiinae parasitoids play a vital role in the reduction of aphid that cause huge economic losses to citrus by attacking even before flowering to fruit formation which ultimately results in decreased fruit production and poor juice contents. The diversity of Aphidiines has never been surveyed in citrus growing localities of Sargodha region. So, their distribution, richness and dominance in the specified area have to be investigated for their bio-control efficiency. Surveys were done during January 2014 to December 2015 from various citrus growing localities using malaise traps yielded 1107 parasitoids belonging to 5 species under 4 genera. Out of them, 2 species (Lipolexis gracilis, L. scutellaris) were new records to the area. Aphidiinae population was abundant in citrus orchards during the months of Feb-April and Oct-Dec while less in remaining months of the year. So this study helps us in knowing the abundance, richness and dominance of Aphidiinae in citrus growing localities of Sargodha, Pakistan and also tells us that in which season or weather Aphidiinae parasitoids are abundant in nature to control aphid pests.
