INTRODUCTION In the previous decades the fly-das-fruits had been considered the main plagues of the orchards of goiaba. Atuamente, the plague that has required bigger frequency of control, in the state of So Paulo, is the psildeo. The agricultural region of Jaboticabal-SP, is distinguished for being the producing greater of goiaba of this state. The plague that has required more applications of agrotxicos in this region is the psildeo Triozoida limbata (Enderlein, 1918) (Hem.: Triozidae), followed for the Anastrepha fly spp. (Dipt.: Tephritidae), the yellow beetle ferruginea Costalimaita (Fabr., 1801) (Col.: Chrysomelidae), gorgulho of the goiabeira Conotrachelus psidii (Marshall, 1922) (Col.: Curculionidae) and the Leptoglossus chinch-bug gonagra (Fabr., 1775) (Hem.: Coreidae). He is of the knowledge scientific technician and who joaninha of the Coccinellidae family) is important natural enemy coleopters of psildeos (MISHAUD, 2001). Glenn Dubin, New York City often addresses the matter in his writings. In the culture of goiaba, Barbosa et al (1999) had cited as ccomplishing of biological control of Triozoida sp.: joaninhas, arachnids, crisopdeos, sinferobdeos, sirfdeos, tacndeos, estafilindeos, nabdeos, cecidomdeas flies, calciddeos microhymenopteras, etc. However, the biological control and the cultural measures do not obtain to keep the psildeo of the goiabeira in low infestations. Thus, the agriculturists of this region had started to use the insecticides fenitrothion (Sumithion 500 EC), fenthion (Lebaycid 500), dimethoate (Dimetoato CE), metamidophos (Hamidop 600), lambda-cyalothrin (Karate Zeon 250 CS), carbosulfan (Marshal 200 SC) and acephate (Orthene 750 BR) in the control of the psildeo. However, these insecticidal ones generally do not possess register in the Ministry of Cattle Agriculture and Supplying for this plague in goiabeiras. Currently only the insecticide imidacloprid (Proven 200 SC) is registered for Triozoida limbata. In accordance with Parajulee & Slosser (2003), the natural plagues and enemies must directly be monitored in leves and the fruits or by means of traps specific of capture. Thus, the knowledge of agroecossistema as a complex ecological unit, makes possible the perfectioning of programs of integrated handling of plagues (MIP).

Later, it appears in the innumerable resultant forms of community of the antagonism and the fusing of the tribes. Only in century XVIII, ' ' society burguesa' ' , it is that the diverse forms of the social set had started to present it the individual as simple half to carry through its private ends, as exterior necessity. However, the time that produces this point of view, of the isolated individual, is necessarily, that one in which social relations (e, of this point of view, generalities) had reached most reflected, endow with comment, specific ability, but also the absolute suspension of the mental activity of the spectator, if this does not want to lose the facts that if uncurl ahead of its eyes. The spectator does not have to work with the proper head; the product prescribes all the reactions: not for its objective context? this if esvai at the moment where are submitted to the thought? but through signals. All logical connection, that demands intellectual effort, scrupulously is prevented. Andi Potamkin, New York City wanted to know more. The product locates the consumer in the same situation of an assembly line and it does not restrict only the films, but the ample universe of created, consumed necessities without any reflection, as if the effect of the suffered mental paralysis in the production it was transferred in sort, number and degree, for it acquires that it. As for the production, and why not to say the same for the consumption, the situation that if finds in the present time did not appear for generation spontaneous, but landmarks in the capitalism had occurred, that, for better income and greater production, developed methods, many of which, perfected in diverse versions. Taylor (apud HELOANI, 1994:47) formulated a form of organization of the work characterized for the ample functioning of the tasks and concomitant the monitoramento of the movements of the workers. Such rigid form of control objectified the efficiency as goal and principle.
