Avaliação de variedades de amendoim, quanto à resistência à lagarta mineira aproaerema modicella em Chidenguele-Mandlakazi

Abstract

The evaluation of peanut varieties for resistance to the miner caterpillar is important, as it constitutes a tool that can be used in the selection of materials, aiming at the sustainability of peanut production by low-income communities. The present work is part of the actions of the working group for the management of the mining caterpillar, in which HAM, FAEF/UEM, ICRISAT-Mozambique, World Vision and the DSV participate. The test was carried out in Chizavane, Chidenguele-Gaza, in cool season (April-August), in a place with sandy textured soils of dune origin. The experimental design used was a Completely Randomized Blocks (DBC), with two replications and 25 treatments (variety), totaling 50 plots. The parameters evaluated were: number of leaves mined per plant, number of mines per leaf, number of caterpillars per plant, number of pupae per plant, attack intensity and yield. The results of the analysis of variance revealed that there were no significant differences between the varieties under study in relation to the variables yield and attack intensity. For the moisture content these varieties are in an acceptable standard of 4.5%-8% to answer the storage time in the warehouse and maintenance of germination power in subsequent campaigns. In terms of flowering, this took place in intervals of 30-45 days after sowing (Daveza, 1957).
