Abstract

The effects of temperature on the development and survival of the seed bug Graptostethus servus (Fabricius) were investigated. Eggs and nymphs were reared at temperatures of 20, 22, 25, 28, and 30 °C on seeds of morning glory Ipomoea nil (L.) Roth until adult emergence. Hatchability and nymphal survival rates increased with an increase in temperature. The developmental period was shortened as the temperature increased. The developmental zero and effective accumulated temperature from oviposition to adult emergence were estimated to be 16.3 ± 1.0 °C and 373.6 ± 9.3 degree-days (mean ± SE), respectively. A larger adult body size in both sexes was observed at higher temperatures. Therefore, temperature increase improves larval and adult performance in G. servus.
