Influence of the temperature and humidity on the development time of eggs and immature stages of Lygus pratensis (Linnaeus, 1758) (Heteroptera: Miridae) in Primorsky krai

Number: 413, Pages: 15 - 19

The data on influence of temperature on the duration of egg development and nymphal ages of the field bug Lygus pratensis (Linnaeus, 1758), which is a potato virus vector, are provided. The development of eggs and nymphs of L. pratensis was studied under various combinations of relative humidity and temperature with a constant photoperiod of 16 hours. The thermal constant for the development of bug larvae was found to be 389.1 °C, 394.2 °C, and 445.9 °C, with an average of 410 °C. The optimal temperature range for the field bug is 20–25 °C, with 65% humidity. Within these limits, there was minimal mortality and the most successful ontogenesis.
