Effects of body size, nutrition intake and mating on longevity and other reproduction aspects of Streblote siva (Lefebvre)

The Streblote siva (Lefebvre) (Lepidoptera: Lasiocampidae) is an invasive defoliator of Conocarpus erectus, Ziziphus spina-christi and Acacia ampliceps in southern of Iran. The relationship between fecundity and body size, egg size, Mating as well as longevity in female insects was studied under laboratory conditions. Effect of host’s quality on growth and gain of S. siva was performed using hosts nitrogen content which was measured by the Kjeldahl technique. The strange data range of larva weight, pupae and adult female insects rose to crescendo of oviposition in order to using different nutrition on plant species. However, there were strange relationships among fecundity and pupal weight, adult weight, there was no significant difference in the egg size of the insect reared on different plants hosts (P
