The magic of the novel lies in something under the surface meaning of the novel itself. With symbolism as a main figurative device, there are various symbols in this novel. Symbol, in literature, is a thing that refers or suggests something more than its literal meaning. In this novel, a lot of symbols are employed, some of them are obvious, others are obscure. This paper will focus on the objective symbols, the things and the people that can be seen by our eyes.展开更多

In this novel, Golding exposes the dark side of human nature. What have left an impressive shocking image in this novel are the three bloody incidents occurring among the originally innocent children. After a brief introduction to Lord of the Flies and comparison and contrast of the three murders, we find that the reasons are not only "the dark side of human nature", but also the death instinct, the instinct of fear and power, which are derived from psychoanalysis. Undeniably, the external factors, such as the social circumstance and natural surroundings are also responsible for the boys' uncontrolled behavior.展开更多

Methods:A net-capturing by direct observing method and fly trap were used to capture adult flies.To determine the fauna of flies in different habitats,4 biotopes including corpse(human, birds,livestock),garbage and decaying organic matters,animal carcasses and human indoor habitat were selected.Big hashing nets(95 cm in diameter) have been used for adult flies capture in these biotopes.Results:In this study,totally 2 418 adult flies from 8 families including Muscidae,Fanniidae,Calliphoridae,Sarcophagidae,Tachinidae,Syrphidae,Anthomyiidae and Conopidae were captured.Among these,1 279 belong to Muscidae and Fanniidae families. Four genera and 5 medically important species captured from two above mentioned families. Conclusions:Based on scientific documentation,2 species of Mvscina stobulons(M.stabulans) and Fannia scalaris(F.scalaris) are reported for the first time in Iran.However M.stabulans is a cosmopolitan species and its presence in Iran was probable.展开更多

Parasites of the Figitidae and Braconidae families emerged from 28.1% of the puparia, and fungal and bacterial diseases destroyed 24.8% of the puparia. Weight and length of the puparia depended on the sanitary status. Two types of cone fly eggs were observed on spruce cones. At least three species ofStrobilomyia (S. Infrequens, S. laricicola, and S. sibirica) attacked cones of Siberian larch (Larix sibirica) in central Siberia.展开更多
