| description | Cockroaches are known for their high reproductive potential, adaptability, and tendency to develop resistance
to insecticides. The successful control requires a comprehensive approach and a combination of different
methods, including fumigation. It is characterized by easy implementation and the ability to process large
areas. The aim of the present study was to determinate effectiveness of fumigation for control of cockroaches
in laboratory conditions, similar to practice. Groups of oriental cockroaches (n = 6) from 2 pig farms were
placed in 5 zones in a lab, close to their natural location: open surfaces (№1 - floor, №2 - lab table, №3 -
opened cupboard), closed spaces (№4 - closed cupboard) and hard-to-reach areas (№5 - upholstered
furniture). Fumigations with cyphenothrin-releasing smoke bomb were performed at a dose of 1g per m3
and
12-hour exposure. Their effectiveness was evaluated by the appearance of a knockdown effect and achieved
mortality.
The tests revealed a knockdown effect at the end of the exposure in 52.78% of cockroaches in open areas
(№1, 2, 3), 58.33% in closed spaces (№4), but not in hard-to-reach areas (№5). At the end of the monitoring
period (96 hours), 100% mortality was found in the groups located in zone №1, 91.67% in zones №2 and
№4, 83.34% in №3 and 49.99% in hard-to-reach places (№5).
The obtained results define fumigation as a highly effective method for controlling cockroaches density in
easily accessible and open areas of the premises. In hard-to-reach areas, additional and targeted treatments should be also implemented. |
