The larvae, commonly called chiggers, are about 170–210 μm (0.007–0.008 in) in diameter, normally light red in color, and covered in hairs; they move quickly relative to size. The larvae congregate in groups on small clods of soil, in matted vegetation, and even on low bushes and plants, where they have more access to prospective hosts.
Heavy infestations on cotton, okra, and sunflower make the leaves turn yellow, curl up and fall off. The insects also secrete honeydew, and sooty mould often grows on this, restricting the amount of light reaching the plant's photosynthetic surfaces and reducing the yield. [5] In many areas, this pest regularly occurs on cotton in epidemic ...

Rarely do fleas jump from dog to dog. Most flea infestations come from newly developed fleas from the pet's environment. [6]

Other common names for thrips ...
Insect pheromones have a highly species-specific effect, meaning that they elicit the desired behavioral response only in biological specificity but not in individuals of other species. For example, although the chemical compounds that act as sex pheromones in butterflies may be the same in different species, the composition of the pheromone ...
