Abstract: 

The results showed that beginning activity larvae Z. tenebrioides was in end January in season 2023 and start February in season 2024 during stage emerging wheat, and peak it in weeks (first, second) from February average (1.50, 2.75) larva/ plant in seasons 2023, 2024 respectively, and spots infested different in field according to intensity infested, pupae of larvae were in soil in end February in stage Tillering, and the adults showed in beginning March, and peak of adults numeric on wheat ears in weeks (second, third) of May in stage milking ears average (1.0, 1.25) adult/ m2 in seasons 20.23, 2024 respectively, and decreasing in beginning June to (0.25) adult/ m2 in stage maturity, Using some preparation in beginning infested of larvae such: mixture attract (Imidacloprid 70%+sugar+bran+plant oil), (Asetamiprid20%+sugar+bran+ plant oil) bioinsecticide fungi Trichoderma harzianum, Sulfur powder, micron Sulfur, Naphthalene. Average efficacy on larvae after month were (93.5, 90.6, 87.3, 47.7, 43.2, 26.8)% respectively. mixture attract (Imidacloprid 70%+ sugar+ bran+ plant oil) were the highest efficient in control the larvae compared with other treatments, then followed mixture attract (Asetamiprid 20%+ sugar+ bran+ plant oil), while Naphthalene was the least efficient.
