Any pest that has experienced the growth and development in order to survive. In the course of existence, the pest is not always entirely beneficial or detrimental to humans. So to recognize and understand them, we would like to briefly introduce the characteristics and effects of some common pests, this more or less influences our lives
1.Termites: Taking advantage of drainage pipes in the walls, underground power lines ... to the high ceilings, sucking termite perforating wall that was built with normal motar (except the concrete> 80),,only to encounter obstacles or pesticidal effect , they perforate wall continuing penetration .
Food source of termites is mainly plant products , in which the most important components is cellulose . Termites digest cellulose thanks to symbiotic organism system living in the termite gut : theflagellate system (flagellata protozoa) and microbial system (Microbial flora) beaking down cellulose for the termite .
On the way to food sources to be primary wood and cellulose , termites that can perforate through a variety of different materials such as soundproof foam , rubber ..., causing serious damage to buildings and other structures, particularly especially furniture, and carrying soil and moisture damaging equipment and machinery, creating conditions for musty fungi, rotting development . Especially in the dry season, living trees provide water for them, especially young trees and damaging agricultural production.
Since the larvae past through molting 5-7 times, worker s accounted for 70-90% of total individuals, assumed most of the work : to find food, build terminary , communication route , care for eggs, rearing larvae, queens, soldiers with food which has been processed through the intestinal tract. Due to the above characteristics, especially characteristics exchanging the outside so these components should be exploited to destroy the entire terminary.
Most of termites receiving food rations from workers, the individuals in the group often lick to exchange feed together, taking advantage of features on application to spreading killing termites. Spreading killer aims at the two main effects: a direct impact on termites through digestive system and kill symbiotically microbial system in the termite gut.
Pheromone regulates the level of the Queens is transmitted from individual to other one, causing effects in the entire termites thanks to two characteristics: licking and exchanging feed together
Soldiers have function to protect group , guard, warn , reconnaissance, support workers to look for food , the head having solid, strong, teeth develop , red-brown head, a single venomous ganglion, when attacking it excretes of acidic white milk. When facing unsual change like loud noise, changes in light intensity, strange smell or communication is broken and soldiers break into the place of incident and alert the population, the same time , one alerts the others generated by transmission of plasm, taking advantage of these features is found where termites being in action
Queens excreting inhibitive pheromone , it works to regulate level in a group as inhibiting the wing development , inhibiting reproduction of preparatory productive level, inhibiting the complete development of the genital apparatuses of workers and soldiers.
