Pine processionary by predators, parasites and viruses which attack the moth at different stages of its life-cycle: Efforts to control the pine processionary have included biological control using "Bacillus thuringiensis", which is effective on eggs and first or second stage caterpillars (in September or October), or insecticides such as diflubenzuron, an insect growth regulator, which can be sprayed from aircraft. Monitoring can include the use of pheromone traps. Older methods used insecticides in oil, inserted directly into nests, or mechanical removal of nests.

Human–animal hybrid in the U.S. Congress, several scientists have argued that legal barriers might go too far and prohibit medically beneficial studies into human modification. Although the two topics are not strictly related, the debates involving the creation of human-animal hybrids have paralleled that of the debates around the stem-cell research controversy. The question of what line exists between a 'human' being and a 'non-human' being has been a difficult one for many researchers to answer. While animals having one percent or less of their cells originally coming from humans may clearly appear to be in the same boat as other animals,
