Energy Allocation of the Wolf Spider Pardosa pseudoannulata under Dietary Restriction

The phenomenon of food shortage is widespread in spider populations, which has a great impact on their growth, development, and survival. Pardosa pseudoannulata dominant species rice fields an important controlling effect pests. In this study, three feeding levels were tested at the juvenile stage (H, high feeding; M, medium dietary restriction; L, severe restriction) two adult (H L). A total six to explore effects restriction longevity, nutrient content, predation by P. [HH (control group), HL, MH, ML, LH, LL]. results showed that continuous (ML LL groups) had negative impacts growth positive longevity. Spiderlings suffered from restrictions during period, when removed upon reaching adulthood (MH LH groups), lifespan started decreasing whilst weight began returning normal. This suggested there might be trade-off between longevity under restrictions. study also found was severely restricted (LH contents could return same level as control group, but predatory ability decreased. When moderately ML spiders improved, while nutrients declined. Our will provide empirical basis for protection effective use agricultural fields.
