Title

LIFE CYCLE AND FECUNDITY OF SPODOPTERA EXIGUA (HÜBNER) (LEPIDOPTERA: NOCTUIDAE) ON FIVE SOYBEAN VARIETIES

Pages

  1-12

Abstract

 Effect of five SOYBEAN varieties (Sahar, JK, BP, Williams and L17) on LIFE CYCLE and FECUNDITY of the beet armyworm, SPODOPTERA EXIGUA Hübner was evaluated at temperature of 25±1°C, 60±5% r.h. and a photoperiod of 16:8 (L:D) h. The preimaginal DEVELOPMENT PERIOD of males and females was longest on L17 (30.17±0.28 and 29.63±0.23 days) and shortest on BP and Sahar. The adult longevity of males and females was longest on Williams (13.86±1.14 and 20.20±1.12 days) and shortest on Sahar (9.36±0.59 and 12.75±0.69 days), respectively. The life span was longest on L17 (44.86±0.85 days) and shortest on Sahar (39.00±0.50 days). The highest percentage of egg and larval mortality was observed on L17 (73.48 and 39.35%, respectively), but the highest percentage of pupal mortality was on Sahar (12.50%). The lowest percentage mortality of egg (57.96%) and larval (10.81%) stages was obtained on Williams. The pupal weight of females was heaviest on Sahar (88.10±3.01 mg) and lightest on BP (73.00±4.18 mg) compared to the other varieties. The highest number of eggs laid per female per day was 58.19±4.53 on L17 and the lowest number of eggs was 37.91±3.01 on BP. The results showed that total number of eggs laid per female was highest on Williams (569.50 ±29.8 eggs) and lowest on Sahar (448.90±19.5 eggs). Knowledge of the biology of S. exigua on SOYBEAN varieties can aid us to detect and monitor the pest infestation, variety selection and crop breeding.
