Abstract :
Ancistrotermes cavithorax, is an economically
important species causing damage to wooden structures and
agricultural crops in Côte d’Ivoire. Toxicities of two new
chemical insecticides (Chlorpyrifos-ethyl and fipronil) were
evaluated against this termite. The results showed that,
Chlorpyrifos-ethyl was the highest toxicity than fipronil. The
LT50 value of chlorpyrifos-ethyl at highest concentration
(2000 ppm) was shorter (4±1.73 Mins.) than that of fipronil
(97.3±1.32 Mins.). Chlorpyrifos-ethyl killed the termite
workers faster than fipronil witch concentrations were
slower than to kill the termites. The LD50 value of
chlorpyrifos-ethyl was shorter (27.119) than that of fipronil
(31.035). The study provides an opportunity to compare the
toxicities of two new chemical insecticides and to use them
effectively in the termite management programs.
