Various reasons have prevented the microbial control of structural pests from reaching the commercial development and practical use achieved with agricultural pests. Microbial products have not been very successful on the ...

Leaf-cutting ants of the genera Acromyrmex and Atta are considered the principal polyphagous pests of the Neotropics. Although some members of these genera are of economic importance, have a broad geographic distribution, ...

This paper reports the occurrence of the longhorn beetle Phoracantha recurva Newman (Coleoptera: Cerambycidae) attacking Eucalyptus citriodora logs in the State of São Paulo, Brazil. This Australian species was introduced ...

The fact that pests are the most abundant species in agricultural settings has broadly precluded the attention to non-pest species and the study of temporal dynamics of diversity in agroecosystems. Because, agroecosystems ...

One of the main goals of the pest control is to maintain the density of the pest population in the equilibrium level below economic damages. For reaching this goal, the optimal pest control problem was divided in two parts. ...

The aim of this paper is to apply methods from optimal control theory, and from the theory of dynamic systems to the mathematical modeling of biological pest control. The linear feedback control problem for nonlinear systems ...

The termite problem in eucalyptus forest plantations in Brazil has been registered since 1908. The main termite pests can be separated in four groups: a) seedling/sapling termites; b) heartwood termites; c) bark termites ...

Forestry companies study the population dynamics of insect pests in Integrated Pest Management for cost effectiveness. The objective of this study was to obtain qualitative and quantitative information on population ...
