¶ … ecosystem, which is a biological environment made up of various organisms, whether living or not, physical constituents which life forms interact with, for example, soil, water, and sunlight. Environmental homeostasis is achieved with the presence of various insects and critters in the ecosystem. This paper will delve into the role wasps' play as biological pest control, nesting habits, and various methods to control the population.
A majority of wasps are parasitic or known as parasitoids, so they prey on insects that would otherwise destroy and eat crops, which makes them advantageous in agriculture. Parasites like wasps lay one or more eggs on the host's exterior or interior body. Wasps are able to conduct such an act by feeding on the pest during their larval stage thus enhancing biological control, which was what Tylianakis (2010) noted in his study that researched biodiversity and biological control services. In another study led by Philips, which investigated the adaptive evolution of an insect introduced for biological control, it described the role of the South American parasitoid wasp Microctomus hyperodae. It was used "for biological control of L. bonariensis. It lays one egg per adultthe larva develops within the living, active weevil then emerges to pupate, while the host dies due to parasitism" (Philips, 2008).
In order for parasitoids to attack their targeted pests, they need to be attracted to the specific object. In a study led by Bianchi, it investigated the effect of nectar in flowering plants have to attract parasitoids. As a result, it was discovered that "the perception of olfactory cues emitted by flowers and host-infested plants drives the movement of the parasitoid...tailoring nectar supply to the requirements of parasitoids holds potential to increase their effectiveness as biological control agents" (Bianchi, 2008).
Despite the variety of wasps, they usually fall into two main classifications, which are solitary or social wasps. The former live and work...
Still, it is not unimaginable, within a lake as large as Victoria that they might also divide into separate populations along very subtle lines of variation -- like mating behaviors or feeding preferences. This sort of interpretation of the situation in Lake Victoria, however, rests upon the notion that the species of cichlid found there evolved from a single ancestral species. Yet, even Meyer acknowledges that this might not be
However even if they are readily available with time the reserves will be depleted and this will pose as a challenge not only to the forest ecosystem but also the energy demands. On the other hand the use of renewable source of energy is beneficial since they are environmental friendly. The renewable energy sources also have some risks such as the use of hydro projects can affect forest ecosystems
Yet, in the world today there is an even greater fuel shortage, that can create an even greater human catastrophe, as trees create the oxygen that makes it possible to breath. A the urgent need to develop more climate-friendly energy technologies is becoming keenly appreciated worldwide. Renewable energy technologies are receiving heightened attention, and modern biomass-based energy -- the use of wood, crop residues and dung as fuel -- is
Of the top 150 medications that are sold by prescription in the U.S. 118 of these are medications that are either "derived from or modeled on naturally occurring substances." (SEAM Global, 2005) Some of the medications that count on habitat presently being destroyed are "aspirin, morphine, vincristine, taxol, digitalis, and most antibiotics."(SEAM Global, 2005) VI.

Safety and Heath in it Environments Applied Business Research: The need for Safety and Health Standards in Hazardous Working Environments in the Information Technology Businesses including IT firms are flooded with IT tools like microcomputers, photocopiers, digital surveillance tools, internet, among others. There is mounting evidence from a review of literature that in the IT work environment, especially the IT industry, present hazardous working environments to workers. Workers in these environments also
Introduction One of the key components of post-Earth survival for humans is transforming another planet or celestial body to be fit for human habitation through supporting human life. The transformation of another planet is commonly referred to as terraforming, which is a term that refers to human colonization of space. Terraforming the planet is associated with some advantages in addition to the potential to support human life/habitation such as contain biosphere
