Effect of two cabbage cultivars on fitness of the most prevalent larval parasitoid of P. xylostella

Syed Abdul Qadeem, Ata ul Mohsin, Humayun Javed and Ajmal Khan Kassi

The research was conducted to test the effect of two different cabbage cultivars on development period of larval parasitoid (Diadegma insulare) which were reared on cabbage pest larval population Plutella xylostella in biocontrol laboratory at PMAS Arid Agriculture University, Rawalpindi. The effect of two different cabbage cultivars Golden Acr and Chinese cabbage were tested on the P. xylostella pupae, the calculated value (28.158%) was higher than critical value (4.09%). The significant variation was found in pupal development period (days) and mean pupal population (0.85) per plant both cabbage cultivars. The higher parasitism level (59 %) was recorded on Golden Acr cultivar and the higher fecundity percentage (61%) was observed on Chinese cabbage cultivar. The total development period of female and male of D. insular were recorded (6.34±0.9 and 6.80±) on Golen acr and (6.73±0.20 and 7.04± 0.38 days) on Chinese cabbage. The total longevity of D. insular female was recorded 19.5± 4.32± and 21.32± 1.56± (days) on G. Acr and C. cabbage cultivars and male longevity period of D. insular was recorded (20.3± 5.18 and 21.9± 1.47 days) on both cultivars. The significant difference was observed on both female and male forewing size. The hind tibia of D. insulare female and male were measured (Fcal=17.6, fcri= 4.19) and (Fcal=38.8, fcri= 4.2), respectively.
