Behavioural ecology of a tea pest,Andraca bipunctata(Lepidoptera: Bombycidae), in the Sub-Himalayan climate of Darjeeling (India)The summer generation (G1) ofAndraca bipunctataWalker in Darjeeling was confined to May-December and the winter generation (G2) extended from August to June. One female laid on average 480 and 526 eggs in G1and G2, respectively. Larvae fed onCamellia sinensisandC. assamicaleaves. Duration of 1st, 2nd, 3rd, 4thand 5thinstars were 7, 7, 6, 6 and 6 days in G1, and 20, 20, 24, 72 and 33 days in G2, respectively. Temperature seems to greatly influence the duration of its life stages. A fungus (Paecilomyces tenuipesSamson), garden lizardCalotes versicolor(Daudin), and several bird species (Stachyris nigricepsBlyth,Spelaeornis caudatus(Blyth) andDendrocitta frontalisHorsefield) were found effective in reducing the population ofA. bipunctata.
