In this research, the ovicidal
activities of the extracts could be due to the fact that the active compounds passed through the egg shell and stopped the segmentation of blastomeres or paralyzed the larvae inside the embryonated egg (25).
Among 11 chemicals tested for ovicidal
effect, two chlorine-based compounds were found to be effective: (i) 3.1 ppm of sodium dichloroisocyanurate; and (ii) 9 ppm of bleaching-powder 101.

They can capture or even kill the parasite, and are classified as endoparasites, predators or opportunistic (ovicidal
