dc.description.abstractInvestigations on biology, morphometries and feeding potential of Mexican beetle, Zygogramma bicolorata Pallister (Chrysomelidae: Coleoptera) and toxicity of weedicides as well as effect of temperature on biological attributes of the bioagent were carried out in Biological Control Research Laboratory, Anand Agricultural University, Anand (Gujarat) during theyear 2011 to 2012. Studies on biology of Z. bicolorata on Parthenium hysterophoms L. revea:ied that the female laid their eggs either singly or in cluster on under surface of leaves. Eggs were oblong in shape, slightly elongated, smooth and the surface was finely reticulated. There were four distinct larval instars. Newly hatched larvae were yellowish in colour and gradually turned in creamy white with the advancement of age. Adults of Z. bicolorata were elongate and oblong in shape. Dorsal surface was strongly convex and glabrous. In general, females found relatively larger in size than males. Average egg, larval, pupal and adult period was 3.93+0.80, 13.87 ± 1.36, 7.40 ± 1 . 1 8 and 32.40 ± 8.05 (males) to 44.53 + 7.33 (females) days, respectively. Entire life-span of female and male completed in 59.13 ± 7.75 and 71.33 ± 8.78 days, respectively. Fecundity, hatching percentage, adult emergence percentage and male to female sex ratio was 669.73 ± 141.34 eggs, 55.75 ± 12.27%, 76.67 ± 14.82% and 1 : 1.26, respectively.en_US
