Field application of bacillus thuringiensis var kurstaki [dipel-2x] against soft and hard ticks

ABSTRACT

Field application of Bacillus thuringiensis [B.t.] var. kurstaki [Dipel-2X] against hard tick, Boophilus annulatus and soft tick, Argas [percicargas] persicus was probed. Hard tick died on infected calves after 6 days post-spraying with Dipel-2X, while soft tick succumbed in its cracks after 6 weeks post treatment. The indirect effect of Dipel-2X on Argas [p.] persicus was also investigated. Egg laying of tick fed on hens injected with 20 and 40 mg Dipel-2X was clearly affected. Molecular structures of hemolymphs collected from ticks got Dipel-2X infected blood meals did not change as demonstrated by SDS-PAGE
