MITES

Mites are eight-limbed group of small animals that are members Superorder Acarina. Different mites with insects (Insecta), but further categorized on spiders. Until now there are dozens of species of mites that have been found, but not yet stable taxonomy mites because there were many changes. In dry conditions the optimum temperature 27 ° C mite can hatch in 3 days, and become sexually mature within 5 days. The tail of the female mite can lay up to 20 eggs per day and can live for 2-4 weeks and can lay hundreds of eggs. A single female mite can reduce up to one million head of population of mites in a month's time. Very rapid rate of reproduction allows populations to adapt and resist mite pesticides, so chemical control methods become less effective when pesticides with the same active ingredient used in a long time. 

Females are diploid mite mite mite whereas males are haploid. That is, a female mite offspring from eggs fertilized by male mites, mites whereas males are descended from unfertilized eggs. When mating, the female mite will avoid the occurrence of conception in some mite eggs to produce males. The fertilized egg will produce diploid females. While the eggs are not fertilized will produce haploid males tions.Mites attack plants by piercing the leaf surface and suck the liquid. Damage due to mite infestation can not be underestimated. In addition to damaging the leaves, mites also attack the stems and fruit potential. These pests attack crops in different seasons because it has the ability to adapt in a variety of habitats, such as moss, soil, grass, and even up to the warehouse. Mites are polyfag, all kinds of plants attacked.

Mites Attack SymptomsGenerally mites hiding behind the leaves and suck the fluids within leaf mesophyll tissue to the damaged tissue. Become damaged and consequently chlorophyll inhibits photosynthesis process of plants. The attack marked the emergence of yellow spots on the leaf surface. The spots gradually widened and changed to brown and finally black. Leaves become twisted (distortion), thickened, shaped like a spoon upside down, and the bottom leaves are colored like copper and fine white threads.
