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 urticae Koch, 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 (r m ) 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.

“…Mites were identified based on Denmark & Muma (1972), Aponte & McMurtry (1995) and DeLeon (1966). The stock colonies were established on arenas prepared with 6-cm diameter flexible plastic sheet discs, floating on water, and castor bean pollen (Ricinus communis L.) as food for the mites (Reis & Alves 1997).…”

Efeito da Densidade de Presa nas Respostas Funcional e Numérica de Duas Espécies deÁcaros Predadores (Acari: Phytoseiidae)RESUMO -Ácaros da família Phytoseiidae são os inimigos naturais de ácaros-praga mais importantes e estudados. Uma questão freqüentemente levantada é se os fitoseídeos podem reduzir altas densidades de ácaros fitófagos a baixos níveis. PALAVRAS-CHAVE: Iphiseiodes zuluagai, Euseius alatus, Brevipalpus phoenicis, citros, cafeeiroABSTRACT -Phytoseiidae mites are the most important and studied natural enemies of pest mites. A question frequently raised is whether phytoseiid may reduce high densities of phytophagous mites. Studies of functional and numerical responses may help to answer this question. The aim of this work was to evaluate the potential predation success of Iphiseiodes zuluagai Denmark and Muma and Euseius alatus DeLeon (Acari: Phytoseiidae) on Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae), vector of the citrus leprosis and the coffee ringspot viruses. Bioassays were performed in the laboratory. Adult females of each predator were isolated in arenas made with citrus leaves (3-cm diameter). Immature stages of B. phoenicis were offered as prey, at the following numbers/arena: 1, 2, 5, 10, 20, 30 and 35 (seven replicates), 45 (four replicates), 55 (three replicates) and 70, 100, 125, 200 and 300 (two replicates). The number of killed prey and of eggs laid by the predators was evaluated every 24h, during eight days. Killed prey was replaced daily by new prey. For both predatory mites, a positive and highly significant correlation was found between the numbers of prey offered and killed. The average daily oviposition rate also increased with the number of killed prey. At the lower densities, E. alatus killed and ate more B. phoenicis than I. zuluagai. The opposite was observed at the highest densities. It is possible that E. alatus can reduce B. phoenicis population even at low prey densities, and I. zuluagai can do the same also at high densities. The fact that E. alatus requires less prey than I. zuluagai suggests that its survivorship may be higher than that of I. zuluagai at low prey densities.

RESUMOA toxicidade de diferentes concentrações de Natuneem a Tetranychus urticae Koch e a dois ácaros predadores, Euseius alatus De Leon e Phytoseiulus macropilis (Banks), foi estudada. Foi avaliada a toxicidade sobre ovos, e o efeito residual e repelente, sobre adultos. O tratamento dos ovos consistiu na imersão em diluições de Natuneem por cinco segundos, e o efeito residual e repelente sobre adultos consistiu na imersão de discos de folhas de Canavalia ensiformes (L.) DC. também em diluições por cinco segundos. Natuneem foi repelente para T. urticae e E. alatus, quando testado nas concentrações de 0,25; 0,50 e 1,00%, e exibiu efeito neutro para P. macropilis. A toxicidade de Natuneem a ovos e adultos foi maior para T. urticae comparada à toxicidade observada para os ácaros predadores. A fecundidade de T. urticae foi reduzida significativamente por Natuneem em todas as concentrações, enquanto para os ácaros predadores a redução foi significante apenas nas maiores concentrações. Natuneem, nas concentrações testadas, apresentou melhor ação sobre o ácaro-rajado e menor impacto para os ácaros predadores.Termos para indexação: Azadiractina, controle, ácaro-rajado, fitoseídeos. ABSTRACTThe toxicity of the Natuneem at different concentrations for both Tetranychus urticae Koch and two predatory mites Euseius alatus De Leon and Phytoseiulus macropilis (Banks) were studied. The toxicity on eggs, and the residual and repellent effects on adults was evaluated. Egg treatment consisted on dipping eggs into Natuneem dilutions for five seconds; and residual and repellent effects for adults consisted on dipping leaf discs of Canavalia ensiformes (L.) DC. into the dilutions for five seconds. Natuneem was repellent for T. urticae and E. alatus at the concentrations 0.25, 0.50 and 1.0%, and exhibited neutral effect on P. macropilis. The toxicity of Natuneem on eggs and adults was greater for T. urticae compared to the toxicity on predatory mites. The fecundity of T. urticae was reduced significantly by Natuneem in all concentration. On predatory mites significant reduction on its fecundity was found at the highest concentrations evaluated. Natuneem was performed better against the twospotted spider mite and exhibited relatively low impact against the predatory mites under the conditions studied.
