DDT-susceptibility tests on Anopheles balabacensis balabacensis Baisas carried out during several years especially during 1979 and 1980 in Sylhet district, Bangladesh, are reported. The LC50 for 1980 was found to be 0.88 plus or minus S.E. 0.02, a 2.38-fold increase of tolerance since 1970 (LC50 = 0.37 plus or minus S.E. 0.07). However, the species is still considered to be susceptible to DDT in Bangladesh. The implication of the use of DDT in controlling malaria transmitted by this species is also discussed.
