Evaluation of insecticidal efficiency of certain new selective formulations against Musca domestica (L).

Five new selective formulations were tested for effectiveness, applicability and costs in controlling the housefly Musca domestica. The tested formulations are Alfacron SB, Alfacron 10 WP, Snip IRB (a.i. Azamethiphos, thiophosphorester), Baygon SB and Golden Marlin Results of laboratory studies revealed that Alfacron 10 WP was the most potent compound against the adult fly (100% mortality was achieved after 20 min from exposure). Snip IRB ranked second with 100% mortality after 40 min, followed by Alfacron SB (50 min.) and Golden Malrin (60 min.). On the other hand Baygon SB did not show complete mortality of houseflies since its maximum mortality was 57.5% after 60 min. Laboratory tests also proved that moistening the fly prolonged the efficacy period of the three tested products from 3 to 6 weeks in case of Alfacron SB, from 4 to 7 weeks for Snip IRB and from 7 to 9 weeks in case of Alfacron 10 WP.
