Diversified systems allow the balance of the ecosystem, reducing the action of harmful insects to monoculture by retention time and immigration of the natural enemies. The objective of this research was to monitor the population of psilids, hemiptera, Psylloidea: Aphalaridae, deeucaliptos in integrated production systems. The evaluations were carried out in an experiment on productive systems integrating the components of eucalyptus crop, pasture and forest in a transition region between Cerrado and Amazonia in the State of Mato Grosso, Brazil. The study was conducted from June 2013 to September 2014, with assessments conducted during periods of drought and rain. The eggs, nymphs and adults of Spondyliaspidinae were quantified in each production system, using as methods of collection, adhesive traps and collection of the eucalyptus branches. The species Glycaspisbrimblecombei and Blastopsyllaoccidentalis were found. The largest infestations of eggs, nymphs and adults were in the dry period. The treatments did not differ for the variable eggs of B. occidentalis, but presented a significant difference for nymphs and adults. The effect of the treatments was not significant for eggs, nymphs and adults of G. brimblecombei. The time did not show a significant difference for the eggs of G. brimblecombei, but significant for their nymphs and adults. It concludes that the psyllids were not harmful to eucalyptus in the studied silvicultural phase and that the diverse landscape contributes to the reduction

The influence of Urochloa brizantha (variety Marandu) grazing systems on Mahanarva spectabilis (Distant) and the entomopathogen Metarhizium anisopliae (Metsch.) was studied to understand the benefits of integrated systems in pest management. The pastoral systems studied were: (M) monoculture, (SP) silvopastoral and (ICLF). We assessed the number, per square meter, of alive spittlebug nymphs or infected by M. anisopliae as well as the demanded number of entomopathogen sprays in each pasture system to control the pest. Throughout the experiment period, M. spectabilis was the unique species found. Silvopastoral had a higher number of alive nymphs and a lower percentage of the infected nymphs compared to pasture in monoculture; however, in both systems, only one spray of M. anisopliae was enough to keep the pest below its threshold. In agrosilvopastoral system, there was no spittlebugs infestation, consequently, none sprays was demanded. Thus, intensified production systems such ICLF may be more sustainable, considering pest aspects. Made available in DSpace on 2020-02-06T18:09:14Z (GMT).
