Life chart and hunter rate of Macrolophus caliginosus (Het: Miridae) by feeding on Tetranychus urticae (Acari: Tetranychidae)

Macrolophus caliginosus (Het: Miridae) is one of the biological control factors of some plant pests in Iran. In this study, the parameters of life table and reproduction of this insect in the growth chamber under temperature conditions of 25±1 °C, relative humidity of 65±10% and light period of 14 hours of light and 10 hours of darkness by feeding from different age stages of two-part tartan mite (TU) ) was evaluated. The experiment was started by using 100 one-day-old insects and the mortality rate of different age stages was determined daily. The results showed that the age-specific (qx) mortality of Macrolophus caliginosus nymphs started at 4 days of age and gradually increased with slight fluctuations. Life expectancy increased slightly after the nymphs hatched, but then declined. Life expectancy at the time of nymph hatching was 17.75 days and at the time of emergence of adult insects was estimated to be 13.95 days. Net fertility and fertility rates, which indicate the reproductive participation of females in each generation for the next generation, were set at 32.91 t 0.17 and 26.35 t 1.02, respectively. Also, the average number of eggs produced by each female was 4.18 eggs per day.
