Role of anuran tadpoles as biological control for dengue larvae

摘要

Dengue is a viral disease caused by Aedes mosquitoes (Diptera: Culicidae) and cause serious illness inpeople community living in tropics. It is able to cause bundles of symptoms and may cause bleedinginternally leading to death of the patient. Currently there is no immunization against dengue disorder butthe most broadly utilized techniques for control of mosquitoes are usage of insecticides and biologicalcontrol. Present study has been designed to observe and compare the consumption of dengue mosquitolarvae by two anuran species, Common Skittering Frog (Euphlyctis cyanophlyctis) and South-east AsianToad (Duttaphrynus melanostictus) tadpoles inhabiting Rawalpindi and Islamabad. The tadpoles anddengue larvae were collected from ponds and pools using dip nets. Six trails were carried with anuranspecies of common skittering frog and South-east Asian toad. Each trail was replicated thrice. TheKruskal-Wallis test present that the total number of consumed dengue larvae among various trialsbetween two species (Common Skittering Frog and South-east Asian Toad) did not differ-significantly(P=0.26) and (P=0.08), while the Wilcoxon test showed that the number of consumed dengue larvae bytadpoles of the two anuran species was P=0.08 which also did not differ significantly. Therefore it wasconcluded that the South-east Asian toad is better in the consumption of dengue mosquito larvae ascompared to common skittering frog.
