تأثير بعض الطرز الوراثية من البامياء في حياتية دودة اللوز الشوكية Earias insulana (Boisd.)

Earias insulana (Boisd.) (Lepidoptera: Nolidae) is an important pest affecting okra. In the 2018 season, the effect of spiny bollworm larvae fed on some okra genotypes on the insect life cycle was studied at the Lattakia Agricultural Scientific Research Center, at 27±2 °C and 65±5% relative humidity, and a photoperiod of 16:8 (L:D) hours. The findings showed that the genotype 10637 was the least preferred for insect feeding, and the mean larval and pupal period were 10.53 and 10.66 days, respectively. The mean pupa weight was 0.040 g and the average female and male life span were 13.20 and 12.60 days, respectively. The fertility rate was 189.60 eggs/female, and egg hatching rate was 86%. However, the genotype 12068 was the most preferred by the insect. The larval and pupal periods were 8.86 and 10.80 days, respectively, and the mean weight of pupa was 0.061 g. The average female and male life span were 20 and 21.20 days, and the fertility rate was 406.80 eggs/female. The results also showed a negative correlation between fruits content of phenolic compounds and the average adults survival and pupal weight. There was a significant positive correlation between the gum and total sugars content and the fertility rate of the insect.
