Abstract
The lace bug, also called the "cotton or bean lace bug", Corythucha gossypii (Fabricius) (Hemiptera: Tingidae) is a common pest from cotton. However it has been reported in another twenty four plant hosts including castor bean (Ricinus communis L.). This work aimed to establish if this insect pest can reduce the life-period of leaves, to assess which is the leaf surface that best represents the total pest population for sampling and to test the efficacy of six insecticides for C. gossypii control in a castor bean crop. The life-period of leaves was negatively affected by the presence of the insect, the larger the number of C. gossypii, the shorter their leaf life. The lower surface best represented the entire population of lace bug with a mean ± standard error of 55.10 ± 4.76, with a 99.60% of correlation, a R2=0.99 and a p 0.0001; compared to 3.44 ± 0.57, with a 66.32% of correlation, a R2
