An insect repellent is a substance applied to skin‚ clothing‚ or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface. There are also insect repellent products available based on sound production‚ particularly ultrasound (inaudibly high frequency sounds). These electronic devices have been shown to have no effect as a mosquito repellent by studies done by the EPA and many universities.[1] Insect repellents help prevent and control the outbreak

Hum of insects According to the author the humming of the insects in the bedroom is as good as the buzz of the dentist’s drill or the sawmill.

A test of various insect repellents by an independent consumer organization found that repellents containing DEET or picaridin are more effective than repellents with "natural" active ingredients. All the synthetics gave almost 100% repellency for the first 2 hours‚ where

Entomology: The Study of Insects and their Relatives Insects and their terrestrial relatives belong to the phylum called Arthropoda and have inhabited the earth for an extensive time. Paleontologists show that the earliest fossils‚ most primitive forms of arthropods date back to the Devonian Period over 350 million years ago (Henning 1981). By the Age of Dinosaurs‚ 300 million years ago‚ insects were abundant in number and diversity. Like the dinosaurs‚ some pre-historic forms of insects were enormous:

Kennedy Evolution Group 4 9/22/13 Lab 1: Insect Diversity and Evolution Introduction: Insects dominate the Earth with vast diversity and number of species. They are arthropods that have articulate appendages‚ a hard exoskeleton‚ compound eyes‚ and an open circulatory system with a dorsal heart. Insects have large populations in many habitats‚ even urban environments such as Chicago. Insects are close relatives to Myriapoda‚ Chelicerata‚ and Crusacea organisms (Hoffmann 63).

Silent Spring Why do we not care about exterminating a whole society of insects‚ but we start riots and revolts over the killing of animals like elephants‚ dolphins‚ whales‚ rhinos‚ and other nearly extinct animals? We have reasons to kill these animals just like the insects‚ the slaughter of these animals temporarily benefits us‚ but what people do think about is what will happen if we eliminate every single insect of a certain species. Rachel Carson is an incredibly brave individual
