تأثير درجات الحرارة المختلفة على حياتية حشرة حفار أوراق الطماطم البندورة (Diptera : Agromyzidae)‎ Liriomyza bryoniae (Kalt.)‎

Abstract EN

Life cycle of tomato leaf miner Liriomyza bryoniae (Kalt.) was studied under different temperature regimes 12, 15, 18, 21, 24, 27, 30 and 16-22 C.

Insects development was greatly influenced by temperature.

The longest life span was 90.5 days recorded at 12 C, and the shortest was 17.6 days recorded at 30 C.

The lowest percent mortality was recorded at 24 C.

Punctures made by the female were also affected by temperature.

The highest number of punctures made by female insect during the whole life span was 2347 punctures recorded at 21C and the lowest was 700 punctures recorded at 12 C.

Female fecundity and fertility was also influenced by temperature too; the highest number of eggs/ female was 160 eggs recorded at 24 C and the lowest was 33 eggs at 12 C.The longest period for oviposition recorded was 10.8 days at 15 C, whereas the shortest was 3 days recorded at 30 C.
