Mass flight and aggregation behavior of the Rice Black Bug (RBB), Scotinophara coarctata are poorly understood. This paper was designed to investigate a possible explanation of the flight and aggregation of RBB by linking these behaviors to the reproduction of the bug and rice phenology. A greenhouse experiment was conducted to determine if the oviposition of RBB is confined to a certain phenological stage of rice. Behavioral experiments showed that RBB discriminated against the seedling stage as an oviposition site. The significantly higher number of egg masses laid on the booting and soft dough stages of rice, as well as the number of visits and the length of time RBB, stayed on these stages indicate a preference over other phenological stages. Results of the study signify that RBB oviposition is restricted to certain phenology of rice. Because of this specific requirement in ovipos.. View More»
