The predatory mite, Neoseiulus californicus(McGregor, 1954) (Acari: Phytoseiidae) is one of the principal natural enemies of tetranychid mites in several countries, promoting efficient control of those mites in several food and ornamental crops. Pest attacks such as that of the spider mite, Tetranychus urticaeKoch, 1836 (Acari: Tetranychidae), is one of the problems faced by farmers, especially in the greenhouse, due to the difficulty of its control with the use of chemicals because of the development of fast resistance making it hard to control it. The objective of this work was to study the life history of the predatory mite N. californicus as a contribution to its mass laboratory rearing, having castor bean plant [Ricinus communis L. (Euphorbiaceae)] pollen as food, for its subsequent use as a natural enemy of T. urticae on a cultivation of greenhouse rosebushes. The studies were carried out in the laboratory, at 25 ± 2°C of temperature, 70 ± 10% RH and a 14 hour photophase. The biological aspects and the fertility life table were appraised. Longevity of 32.9 days was verified for adult females and 40.4 days for males. The intrinsic rate of increase (rm) was 0.2 and the mean generation time (T) was 17.2 days. The population doubled every 4.1 days. The results obtained were similar to those in which the predatory mite N. californicus fed on T. urticae.

<p>El chinche de encaje, Corythucha gossypii (Fabricius) (Hemiptera: Tingidae), es un insecto plaga del algodón, pero ha sido reportado en más de veinticuatro hospederos, incluyendo higuerilla (Ricinus communis L). El objetivo de este trabajo fue evaluar si esta plaga disminuye el periodo de vida útil de las hojas, establecer la superficie de muestreo de la hoja que mejor representa las poblaciones de esta plaga y la eficacia de seis insecticidas para su control en higuerilla. La vida útil de las hojas fue negativamente influenciada por la presencia del insecto plaga; a mayor número inicial de insectos, menor fue el tiempo para la pérdida de hojas. La superficie del envés fue la que mejor representó la población de C. gossypii con un promedio ± Error Standard (ES) de 55,10 ± 4,76 de individuos y una correlación con la población total de 99,60%, R2 =0,99 y p &lt; 0,0001; comparado con 3,44 ± 0,57 individuos y una correlación de 66,32%; R2=0,44 y p &lt; 0,0001 para la superficie del haz. El orden de eficacia de control para 3 días después de la aplicación de los tratamientos fue tiametoxam + lambdacihalotrina (0,00%), spinetoram, (0,00%), malation (20,35%), tiametoxam (38,62%), dimetoato (86,94%) e imidacloprid (87,33%); para 7 días fue tiametoxam + lambdacihalotrina (0,00%), spinetoram (21,46%), malation (38,77), tiametoxam (50,84%), dimetoato (86,14%) e imidacloprid (90,37%). Los datos de muestreo, a partir de 16 días, presentaron una gran pérdida de unidades experimentales, lo que imposibilitó el análisis de los resultados, después de ese tiempo.</p><p> </p><p><strong>Effect of Corythucha gossypii on Castor Oil Plant Leaves: Sampling Criteria and Control by Insecticides</strong></p><p>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 &lt; 0.0001; compared to 3.44 ± 0.57, with a 66.32% of correlation, a R2=0.44 and a p &lt; 0.0001 for the upper surface. Efficacy of control after three days of insecticide application was: thiamethoxam + lambdacyhalothrin (0.00%), spinetoram, (0.00%), malathion (20.35%), thiamethoxam (38.62%), dimethoate (86.94%) and imidacloprid (87.33%). After seven days of insecticide application the efficacy was thiamethoxam + lambdacyhalothrin (0.00%), spinetoram (21.46%), malathion (38.77), thiamethoxam (50.84%), dimethoate (86.14%) and imidacloprid (90.37%). Results obtained after 16 days lacked many sampling unit leaves, which made their analysis meaningless, after that period of time. </p>

This study aimed to evaluate the allelopathic activity of aqueous extracts of castor bean (Ricinus communis L.) leaves on germination and initial growth of canola (Brassica napus L.) and radish (Raphanus sativus L.) seedlings. Two experiments were conducted, usingcanola seeds for the first, which was installed in a 2x7 factorial scheme (with two photoperiods – dark and light and seven extracts concentrations - 0, 1, 2, 4, 8, 16 and 32%). The second experiment consisted of an evaluation of radish seed germination submitted to seven concentrations of the extracts in the dark photoperiod. The germination of the canola seeds was reduced in the dark, and the use of extracts at concentrations of 16% and 32%inhibited seeds germination for both studied photoperiods. The radish seed germination was completely inhibited when the concentration of 32% was used, however, at the concentrations of 4, 8 and 16% a reduction on rootand hypocoyl development of the seedlings were observed, affirming the high allelopathic potential of castor bean aqueous extracts on canola and radish.
