Abstract
Development of the semi-aquatic acridid Cornops aquaticum on Eichhornia crassipes (Pontederiaceae) was investigated in the laboratory. Influence of constant (12 and 27 °C) and variable (36/3 °C and 36/4,5 °C) temperatures as well as constant (24 h day) and variable (14 h day/ 10 h night) photoperiods were analysed. The highest survival of nymphs (72 %) was obtained under an extreme photoperiod (24 h day) and constant temperature (27 °C). Both photoperiod and temperature were important for the development and number of nymphal stages, indicating a synergic effect.
