In a generic mutualistic relationship, both organisms gain fitness benefits from the interaction, but are not dependent on each other for survival. Yucca Plants And Yucca Moths 2862 Words | 12 Pages. 4 0 obj 10.3732/ajb.1600053 This spiky-leaved evergreen plant and its Yucca Moth pollinator depend on each other for survival. Plants in the first group are pollinated by ovule parasites. In Central America the Yucca is known as a wild plant but it also serves well as a house plant. Many species of yucca plant can be pollinated by only one species of yucca moth, while those yucca moths use the yucca flowers as a safe space to lay their eggs. However, some pupae remain dormant for more than a year. The plant is pollinated only by one type (several related species) of moth, while the moth is absolutely reliant on the yucca plant to sustain its young. The pollen ball is then "stuffed" or "combed" into the stigma of the various flowers she visits. Elle est appréciée et connue pour son aspect exotique. Female moths pollinate Soapweed by intentionally collecting and transferring pollen between flowers. The pollination in which pollen grains are transferred to the stigma of the same flower or different flower of the same plant is called self-pollination. In the associations involving yucca moths, the female moth uses sex-specific unique tentacular mouthparts (Fig. Yucca flowers are a certain shape so only that tiny moth can pollinate them. The yucca–yucca moth interaction is one of the most well-known and remarkable obligate pollination mutualisms, and is an important study system for understanding coevolution. In order for pollination to occur, masses of pollen must be forced down into this central stigmatic hole. Can get delivered from stamen to stigma with less waste –Floral cues and attractants: •Color and shape •Scent •Warmth (thermogenic plants: rare) Skunk cabbage. 10.3732/ajb.1600053 Open App Continue with Mobile Browser. The adult yucca moth does not need to feed because it is so short lived. The sharp, sword-like leaves of the Yucca plant provide protection for the eggs, and the seeds of the plant provide a source of food for newly hatched larvae. This is still the case with a number of close relatives of Tegeticula, members of the Prodoxidae family. Pollination class 12th. The pistil (female part) of each flower ends in a three-lobed stigma.In order for pollination to occur, masses of pollen must be forced down into this central stigmatic hole. This yucca moth is inside the flower of a yucca, Yucca glauca. The interaction The interaction among yuccas and yucca moths is cited as a classic example of the importance of mutualism in specialization and diversifi cation. The Yucca plant is often pollinated by a special type of insect called a Yucca Moth. Yucca et Pronuba.--c'est l'un des cas les plus célèbres de la dépendance mutuelle entre une plante et ses polli- insectes provenance ; il y a une sorte de partenariat dans leurs processus de reproduction, chacun étant nécessaire pour l'autre. Examples of pollination are seen in the pollination of Yucca plant by moths and self-pollination in wheat and barley. Yucca plants make good indoor plant and some varieties can even be kept outdoors as a decorative all-season plant or tree. In turn, the yucca plant is the only host plant for yucca moths. Instead, it has tentacles around its mouth that serve a very important function and make possible its job as a pollinator.
