“…At this stage, the plant presented five mainstem nodes from the terminal to the uppermost firstposition white flower. Helman et al (2011) protected cotton plants from the emission of the first flower to the opening of the boll of cotton leafworm A. argillacea and obtained a productivity increase of 22.6%.…”

The cultivation of soybean near to cotton areas has favored the migration of lepidopteran pests between those crops, including the soybean looper, Chrysodeixis includens, which usually attacks soybean leaves but can also attack cotton plants. The objective of this study is to identify the density of C. includens larvae capable of decreasing cotton productivity. Six treatments (0, 2, 4, 6, 8 and 16 larvae.meter -1 ) with five replications were arranged in a completely randomized block design. Plants of cultivar FM 944GL at stage F2 were protected by PVC cages (length, 1.0 m; width, 1.0 m, height, 1.6 m) covered with organza fabric and infested with thirdinstar larvae. Crop yield and defoliation data were subjected to analysis of variance using the F-test and regression analysis. The results indicated that the presence of two third-instar larvae.m -1 did not affect cotton yield in the F2 phase whereas four or more third-instar larvae.m -1 decreased cotton yield. The rate of defoliation was 4%, 10%, 6%, 13%, and 24% in the treatments with two, four, six, eight, and sixteen larvae, respectively.

“…The reduction in cotton yield by A. argillacea was evaluated by other researchers [14], who found that the reduction in cotton yield was a consequence of the reduced boll weight or number. According to [15], this can be explained by the ease with which assimilates reach these plant parts.…”

“…La densidad de larvas en el cultivo del algodonero se incrementa con la finalización de la floración (Helman et al, 2011). Una larva puede consumir, en promedio, 66 cm 2 de hoja, ocasionando hasta un 30% de perjuicios cuando no es controlada y puede reducir hasta un 67% la producción del cultivo (Gallo et al, 1988).…”

Introducción: Alabama argillacea es una especie de polilla ampliamente distribuida por toda América Central y Suramérica. Es una plaga potencialmente dañina que afecta los cultivos de algodón. A pesar de lo anterior, no existe información concreta sobre su ciclo de vida. Objetivo: Por tanto, el objetivo de nuestro trabajo es la descripción de los estadios inmaduros (larva y pupa) de esta especie y de algunos aspectos de su historia natural. Métodos: Se observaron y realizaron mediciones a los diferentes estadios de 65 individuos, los cuales inicialmente se colectaron de larvas. Se describieron los diferentes estadios en cuanto a morfología, tiempo de duración y algunos aspectos de su historia natural. Resultados: De forma general la descripción morfométrica coincidió con otros estudios. El tiempo de duración del estadio de pupa difirió con lo registrado en la literatura. Conclusiones: Se observaron diferentes comportamientos de la larva sobre plantas del género Abutilon a los descritos en la literatura sobre el algodonero, lo cual es justificable porque se trata de plantas de diferente género.
