Studies on the Influence of the Parasitoid, Apanteles Glomeratus on the Metabolite Levels of the Host Pieris Brassicae
The body weight of the host was considerably reduced on attack by the parasitoid, Apanteles glomerulus Linnaeus. It varied from 466.65 ± 87.78 mg to 177.94 ± 52.01 mg. Average weight of the parasitoids per host was 268.54 ± 80.86 mg and individual parasitoid weighed 3.12mg. There was a reduction in the total body lipid: from 8.85 ± 1.27% (wet wt) in the normal caterpillar to 1.93 ± 0.42% in one batch and to 5.16 ± 0.80 in another batch of infected caterpillars. The haemolymph protein content of the host also showed a reduction from 9.89 ± 1.29 to 3.59 ± 0.76%.
