Abstract

• A monthly field study was conducted to determine the preferred biting behavior of mosquitoes on different specific parts of different coloured cattle body in Taikkyi Township, Yangon Region from March 2017 to November 2018. Outdoor cattle bait mosquitoes collection was done using WHO sucking tube from 18:00 hours to 24:00 hours for 3 days. Anopheles and Culex mosquitoes were collected for 45 minutes in every hour on the specific parts of the cattle body. Collected mosquitoes were placed in specific body parts labeled paper cups. Next day morning species identified was done all collected mosquitoes according to different mosquito identification key. Result revealed that the highest number (n=1798) of mosquitoes were collected in September followed by n= 1409 in March and lowest was collected in n=226 in May by cattle bait collection. The biting behavior of mosquitoes were found to be the highest (n=2592, 34.39%)on black cattle, followed by (2566,34.05%) on white cattle lowest was observed (2378,31.56%) on Brown coloured cattle. The highest number of biting behavior on specific part of body was found Elbow from Bracelets (1611, 21.38%) followed by Knee from Anklebone (1108, 14.70%), Fingertip (846,11.41% ), Tiptoe (887,11.77%) lowest was observed on Head (108,1.43%). When compared with specific parts of different parts of different coloured cattle was found the highest number of mosquitoes were collected from Elbow to Bracelets (n=552,21.51%) white, 522,21.95% on Brown and 537, 20.72% on Black cattle followed by 549 21.18% on Tiptoe of black cattle, 395, 16.61% and 430, 16.59% on Knee to Anklebone of Brown and black cattle body parts. Lowest mosquitoes were observed (13, 0.51%), (47,1.98%) and (48,1.85%) on Head of all White, Brown and Black coloured cattles. In conclusion biting behavior of mosquitoes were observed differ to different parts of the cattle body. Tiptoe, fingertip, Elbow from Bracelets and Knee from Anklebone were mostly bitten by mosquitoes. Mosquitoes were found highly attack to Elbow from Bracelets and Knee from Anklebone followed by tiptoe, fingertip of the cattles. Although very low on Head.
