Nepetalactone is a name for multiple iridoid analog stereoisomers.Nepetalactones are produced by Nepeta cataria and many other plants belonging to the genus Nepeta, in which they protect these plants from herbivorous insects by functioning as insect repellents.
The insects attracted to the insectary plants will also help the other nearby garden plants. Many members of the family Apiaceae (formerly known as Umbelliferae) are excellent insectary plants. Fennel, angelica, coriander (cilantro), dill, and wild carrot all provide in great number the tiny flowers required by parasitic wasps. Various clovers ...
Entomophily, pollination by insects, often occurs on plants that have developed colored petals and a strong scent to attract insects such as bees, wasps, and occasionally ants (Hymenoptera), beetles , moths and butterflies (Lepidoptera), and flies . The existence of insect pollination dates back to the dinosaur era. [13]
Many flowers and plants deemed safe for humans are toxic for cats, according to the American Society for the Prevention of Cruelty to Animals (ASPCA). So, before you buy flowers for your next big ...
The bright leaves of the Venus flytrap (Dionaea muscipula) attract insects in the same way as flowers. Spiders can be the prey of aggressive mimics. The assassin bug Stenolemus bituberus preys on spiders, entering their web and plucking its silk threads until the spider approaches. This vibrational aggressive mimicry matches a general pattern ...
The plants' ecological strategy varies; several species of Stapelia, for example, attract carrion flies that futilely lay their eggs on the flower, where their larvae promptly starve for lack of carrion. Other species do decay rapidly after ripening, and offer the visiting insects large masses of food, as well as pollen and sometimes seed to ...
This allows plants that may require an animal pollinator to stand out from other flowers or distinguish where their flowers are in a muddied background of other plant parts. [5] For the plant, it is important to share and receive pollen so they can reproduce, maintain their ecological role, and guide the evolutionary history of the population.
The iridoid that is deposited on cats who have rubbed themselves against the plants and scratched the surfaces of catnip and silver vine (Actinidia polygama) leaves repels mosquitoes. [35] The compound iridodial , an iridoid extracted from catnip oil, has been found to attract lacewings that eat aphids and mites.
