laboratory conditions, indicating the resin collection is prophylactic rather than therapeutic. Honey bees also incorporate plant-produced resins into their nest architecture, which can reduce chronic elevation of an individual bee's immune response. When colonies of honey bees are challenged with the fungal parasite (Ascophaera apis), the bees increase their resin foraging. Additionally, colonies experimentally enriched with resin have decreased infection intensities of the fungus. Transgenerational zoopharmacognosy Zoopharmacognosy can be classified depending on the target of the medication. Some animals lay their eggs in such a way that their offspring are the target of the medication. Adult monarch butterflies preferentially lay their eggs on toxic plants such as milkweed which reduce parasite growth and disease in their offspring caterpillars. This has been termed transgenerational therapeutic medication. When detecting endoparasitoid wasps, fruit flies (Drosophila melanogaster) lay their eggs in leaves with high ethanol content as a means of protection for their offspring. These wasps, especially those of the Leptopilina genus, will inject their eggs in approximately 80% of fruit fly larvae. As these wasp eggs develop, they will consume extensively through the larvae. To combat this, the fruit fly larvae will consume a large amount of ethanol from the food source to medicate themselves after wasp infection. Specifically, as the wasps are consuming more of the larvae, they will unknowingly consume more ethanol, which promptly leads to their deaths. This has been termed transgenerational prophylaxis. Value to humans In an interview with Neil Campbell, Eloy Rodriguez describes the importance of biodiversity to medicine: "Some of the compounds we've identified by zoopharmacognosy kill parasitic worms, and some of these chemicals may be useful against tumors. There is no question that the templates for most drugs are in the natural world."
