Polyphagous Beetle Research Paper

672 Words3 Pages

Defense Against the Polyphagous Shot Hole Borer There has been a recent infestation on the campus of the University of California, Irvine that has forced many of the trees on campus to be cut down to prevent the spread of the infestation. The invasive species is known as the Polyphagous Shot Hole Borer (PSHB).The PSHB is a type of ambrosia beetle, and these beetles burrow and excavate tunnels deep inside the the vascular tissues of trees and cultivate the fungus that accompanies the beetles. The PSHB and its fungus, Fusarium euwallacea, have a mutualistic symbiotic relationship. The beetles provide an environment for the fungus to grow, and in turn the fungus becomes nutrients for the larvae and adult beetles. Because the fungus is cultivated in the xylem of the tree, the fungus obstructs water and mineral transport throughout the tree. The …show more content…

The main concern is that the fungus that the PSHB carries blocks water and nutrient transport in the xylem, and this results in fusarium dieback. Even if we cannot completely get rid of the invading PSHB species, if they cannot cultivate their fungi in host trees, they will not be able to feed or reproduce. If a tree has a natural fungicide, then it will become unsuitable to house the beetle-fungal complex. A study was conducted in 2007 in which the essential oil of Melaleuca alternifolia, a tea tree, was tested for its antifungal activity. In the study, all the tested fungi was susceptible to the tea tree oil (TTO) and its components [3]. Because of its ability to affect a wide range of fungi, TTO may also affect fusarium euwallacea and prevent the PSHB from being able to cultivate it within the tree xylem. I hypothesize that TTO will act as a natural fungicide and prevent or lessen the severity of fusarium dieback on infested trees. The independent variable is the percent amount of fungicide recommended used on a tree, and the dependent variable is amount of fungus present in the

    The Beetle, an 1897 novel by Richard Marsh, takes place in the dark and supernatural country of Egypt, where said creature of horror is believed to change its form at will, and use its hypnotic powers to prey upon young middle-class English people. The novel appears to, more often than not, deal with society’s anxiety surrounding the turn of the century. Marsh analyses the opposing views of sexuality and femininity through the exchange of sexual manipulation in the novel. By numerous means of sexually influenced interferences, and the degenerate figure of the colonized, The Beetle builds a sort of parallel between the practices of the British Empire, allowing the British characters to see their individual wrongdoings in a horrific other form.

    Everyone leads different lifesytles and varying experiences, but no matter how diffrering a humans life is, it all ends with death. The essay “The Death of The Moth” was published posthumously in 1942, a year after Virginia Woolf lost a battle with depression and mental illness, and at age 59 committed suicide. Virginia Woolf 's "The Death of the Moth" shows the audience the power of death through a short narration about everyday, yet very symbolic moth. Woolf uses her own experience of watching a moth die to apply it to a larger theme. Woolf connects a simple moths lifespan to paint a gorgeous picture of “life” and then destroys it right in front of the audience 's eyes, to leave a lasting impression of Woolf 's perception of life and death.
