Ecology and strategy of a Belostoma Oxyurum (Dufour) population (Hemiptera, Belostomatidae)

This paper constitutes the first intent to elucídate annual cycle events in a B. oxyurum field population, as well as its adults density changes through the year in Los Talas Pond (Province of Buenos Aires, Argentina).The main events recorded were: maturity, oviposition, incubation, hatching, nympha...
