SURVEY FOR HEMATOPHAGOUS FLIES AND TRYPANOSOMA SPECIES IN IKARA AND KUBAU LOCAL GOVERNMENT AREAS, KADUNA STATE, NIGERIA

 

Abstract

 

A study of the species composition and distribution of hematophagous flies was conducted between dry and wet seasons, at Ikara and Kubau Local Government Areas, Kaduna State, using Biconical (Charlier and Laviessiere, 1973) and Nzi traps (Omoogun, 1994). Survey for the occurrence of Trypanosoma species in cattle in the study area was also conducted during these periods. Twelve traps each was placed for 48hrs in four districts in each of the local government areas and the trap catches were harvested every 24hrs.A total of 232 flies were caught during the study period and their occurrence differ between the two local governments. Kubau Local Government had 105(45.3%) while Ikara Local Government had 127 (54.7%).The specific occurrences of the hematophagous flies caught were: Stomoxys calcitrans107 (85.3%), Tabanus 9(7.1%) and Glossina 0(0.0%). Overall percentage of fly catches per trap was 130 (56.0%) for biconical and 102(44.0%) for Nzi traps respectively. The highest number of flies caught was during wet season {212 (91.4%)} while in dry season only 20(8.6%) flies were caught during the study. There was significant association (P=0.002) between the flies occurrence and the two seasons of the year. While there was no statistically significant association (P=0.07) between the number of flies caught and the type of trap used. The prevalence rate of Trypanosoma infection in cattle in the local government areas was 50% prevalence each of infection due to T. vivax and T. brucei respectively. There was no significant association between the occurrence of the Trypanosoma infection and the Local Government Areas under study.
