Abstract: The objective of this article is to find out the life history traits and food consumption of Hog Plum Leaf Beetle Podontia 14-punctata or Podontia quatodecimpunctata (Chrysomelidae: Coleoptera). However, the result of life history traits Podontia 14-punctata reveals that the pre-oviposition, oviposition and incubation period of the hog plum leaf beetle were agverage 19.8±0.55, 8.0±0.21 and 5.7±0.15 days, respectively. The average number of eggs laid in a cluster by the female was 41.5 and hatching rate was 96.27%. The eggs were, more or less, oval round and at the end freshly laid eggs become yellow in colour, naked and are arranged in multiple layers usually two, before hatching it became dull yellowish-white. Dark black head and legs of grub were visible through egg membrane just before hatching. The mean duration of the 1st, 2nd 3rd, 4th instars larvae and were 3.3±0.15, 3.4±0.16, 3.3±0.15 and 3.7±0.15 days. But the mean duration of the pupa varied from 14-17 days days. The total developmental periods from egg to adult were 37.1 days. In addition, a larva consumed leaf of hog plum 32.127 cm2 or 3.8234 g during its total developmental period. But the final instars larvae consumed the highest amount of leaf.
