Aspects of flight in the cocoa mirids Sahlbergella singularis Hagl. and Distantiella teobroma Dist. (Heteroptera, Miridae)
Flight in cacao capsids has been little studied, in spite of its importance in the distribution of these pests leading to the colonisation of new cacao farms. Preliminary observations on the flight habits of the cacao capsid Sahlbergella singularis revealed that two types of flight can be distinguished. (a) "Trivial" flight in which adults fly clumsily for only short periods with frequent interruption; (b) "Migratory" flight in which adults fly steadily for long periods without interruption. Adult males tethered by pins on the dorsum of the thorax flew continuously for over 80 minutes, and females flew for over 30 minutes. The ecological significance of these flights in relation to capsid attack in a new cacao plantation is discussed
