Examples of these types of species are birds‚ plants‚ amphibians‚ insects‚ fish‚ microbes‚ and mammals. The wetlands also provide these species with food and breeding grounds Wetlands don’t just support the species that live in them they also help the land around them.

Results and discussions The experiment was conducted in order to determine the activity of plant extracts on the adult and last larval instar of T. confusum. In all cases‚ considerable differences in insect mortality were shown with different plant extract‚ different concentration at the same exposure period 24 hrs. The 24 hrs bioassay is a major tool for evaluating the toxicity of phytotoxins‚ and a number of researches have been applying this method to assess the toxic effect of different plant

pheromones which helps them to identify each other for specific purposes ranging from insects to mammals. Pheromones in mammals is divided into Releaser pheromone and Primera pheromone ‚ as proposed by Wilson and Bossert in 1963. The releaser is the pheromone which induce and mediate behavioural changes‚ and the primera is the pheromone which initiates changes in development such as sexual maturation. Furthermore‚ the insect pheromones are divided into; sex pheromone‚ aggregation pheromone‚ alarm and trail

Before mass agriculture became de rigeur‚ reducing plantlife to far-reaching swathes of identical crops‚ a number of insects were responsible for pollinating plants. As farming became more efficient and reduced the once varied landscape to a monotone green‚ so the farmers began to encourage the populations of bees to carry pollen from one flower to another. This is a fantastic

stage is adulthood. At this stage‚ each bee assumes a role within the colony. The assumed roles are the working bee‚ the male reproductive‚ or the queen thus continuing the life cycle of the bumblebee. The bumblebee also serves as a host for other insect life cycles such as the coponid flies and the nematodes parasite. These parasites target the bumblebee in mid-air‚ during hibernation‚ and when the bees dig looking for a proper nest to begin the hibernation season. Bumblebees are a food source for
