Chromolaena odorata (Asteraceae: Eupatorieae) is a sprawling shrub native to the Americas, and a destructive invader of much of the humid tropics and subtropics of the Old World.Opportunistic native-range exploration in 1995 identified a stem-boring weevil, Lixus aemulus, as a promising biological control candidate agent.Host-specificity testing wa
Abstract Myrmecophilous butterflies can establish complex symbiotic relationships with ants.A caterpillar wandering among the brood of the aggressive ponerine ant Neoponera villosa was found inside the core of a nest built in the myrmecophytic bromeliad Aechmea bracteata.This is the first caterpillar found living inside a ponerine ant nest.Its DNA
Establishing field water balances is difficult and costly, the variability of their bempresas.com components being the major problem to obtain reliable results.This component variability is presented herein for a coffee crop grown in the Southern Hemisphere, on a tropical soil with 10% slope.It was observed that: rainfall has to be measured with an
