Effects of sex ratio on different biological parameters of (Distant) (Hemiptera: Miridae) adults and their offspring: prey preference for (Sulcer) (Hemiptera: Triozidae).

In the present study, the influence of three sex ratios (1:1, 1:2, and 1:3; female:male) of the mirid (Distant) (Hemiptera) on different biological parameters and on its offspring was evaluated. The prey preference of different developmental stages of this predator for different nymphal instars (N) of (Sulcer) (Hemiptera: Triozidae) was also evaluated. The fertility was significantly higher (24 nymphs/female) in the 1:3 sex ratio than in the 1:1 and 1:2 sex ratios (14 and 16 nymphs/female, respectively).
