Established German cockroach (Blattella germanica L.) infestations are difficult to manage along various components of the value chain of agricultural commodities in storage, restaurants and residential areas due to their behavioural and physiological adaptability. The German cockroaches have high reproductive potential. Five concurrent B. germanica age-related experiments were run in a completely randomized design with 10 replications. The 1-, 2-, 3-, 4- and 5-day old German cockroach nymphs experiments were conducted under controlled conditions. Each age group consisted of 10 nymphs and was put in 250 cm3 container that contained MIB. One gram of Mohlolo insecticide bait and moistened cotton wick were put at the bottom center of the 250 cm3 containers with nymphs classed according to their respective ages. The mortality of the age-related stages of cockroaches was significantly affected by the period of exposure to MIB. The period of exposure contributed 97, 100, 100, 100, 100 and 98 of the total treatment variation of age-related mortalities [ABSTRACT FROM AUTHOR] |
