| Abstract | ||||
| The cabbage looper (Trichoplusia ni) is a medium-sized moth in the family Noctuidae, a family commonly referred to as owlet moths. Its common name comes from its preferred host plants and distinctive crawling behavior. The cabbage looper eggs are generally yellow-white in color, dome-shaped, and patterned with ridges. They are 0.6mm in diameter, they are usually laid singly on leaves. In one day, 40-50 females can lay 1000-2000 viable eggs. Viable eggs hatch after about three days The first record is the hatching process time (hatching period) of fully developed embryo within the egg was firstly video recorded. The elapsed time interval from the start till the completion of hatching process was calculated for three video recorded shots for egg eclosions of the full mature embryos of the cabbage looper,ranged between 12:30 minutes with an average interval period amounted to 21 minutes after feeding on Cabbage plant leaves. | ||||
