Comparative evaluation of some commercial spray-applied insecticides as control method against Blatta orientalis
Betina Boneva - Marutsovaorcid, Plamen Dimitrov Marutsov, Georgi Zhelev Georgiev
Abstract: Cockroaches are globally distributed pests with high epidemic importance. Their role as spreaders of many infectious and parasitic diseases in animals and humans determines disinsection as the main anti-epidemic measure. The present study compared the effectiveness of spray application of different commercial insecticides against a field population of oriental cockroaches (B. orientalis) under laboratory conditions. A very high efficiency of fipronil (100% mortality) was found as early as 37-48 hours after treatment and a high efficiency of synthetic pyrethroids - 95-97% mortality at 49-60 hours. With the organophosphate derivatives (Dichlorvos) low mortality (37%) and unsatisfactory efficiency was achieved. The obtained results confirm the insecticides from the phenylpyrazole group and the synthetic pyrethroids, in spray-applied forms, as an effective method of fighting the oriental cockroach.
