“…However, the sex ratio for G. occidentalis was significantly higher when feeding on T. pacificus than on E. willamettei. It is not clear what caused the lower sex ratio when fed E. willamettei, especially since other predatory mites exhibit higher sex ratios on more favorable than less favorable prey (Escudero and Ferragut 2005). The combined life history parameters for G. occidentalis feeding on either spider mite resulted in very similar demographic rates.…”

We evaluated the influence of temperature on demographic parameters of two common vineyard pests, the Pacific spider mite, Tetranychus pacificus McGregor, and the Willamette spider mite, Eotetranychus willamettei (McGregor) (Acari: Tetranychidae). Additionally, we investigated the effects o f temperature on their shared predator, the western predatory mite, Galendromus occidentalis (Nesbitt) (Acari: Phytoseiidae). The intrinsic rate of increase (r m ) was higher for T. pacificus than E. willamettei at 15 and 28°C, but similar at 22°C. G. occidentalis achieved a higher r m than T. pacificus from 15 to 28°C, but the difference was significant only at 22°C. At 34°C, the r m for both T. pacificus and G. occidentalis was negative, while E. willamettei did not develop at this temperature. Prey species did not affect demographic parameters of G. occidentalis. These results suggest that higher temperatures favor T. pacificus over the less damaging E. willamettei, and may also reduce the effectiveness of G. occidentalis.

“…In addition, no studies have estimated demographic parameters for G. occidentalis feeding on E. willamettei, and yet prey species can be an important factor determining the population growth and effectiveness of mite predators (e.g. Escudero and Ferragut 2005;de Vasconcelos et al 2008).…”

“…Vasconcelos et al (2008) also reported that the P. fragariae oviposition period lasted 17.1 days, which was close to the results found in the present study of 17.5, however, the longevity of males and females, as well as the fertility of P. fragariae fed with T. urticae, at the same temperature of this study were lower. Escudero and Ferragut (2005) and Abad- Moyano et al (2009) assessing the biological aspects of P. persimilis when fed T. urticae found the oviposition rate of 3.9 and 3.7 eggs/female/day, respectively, which was higher.…”

Davies et al (2009) found values for P. persimilis of 0.6 and 1.4 days for the larvae and protonymph development, respectively, when fed with T. urticae.…”

Predatory mites that belong to the Phytoseiidae family are one of the main natural enemies of phytophagous mites, thus allowing for their use as a biological control. Phytoseiulus macropilis (Banks, 1904) (Acari: Phytoseiidae) is among the main species of predatory mites used for this purpose. Tetranychus urticae Koch, 1836 (Acari: Tetranychidae) is considered to be one of the most important species of mite pests and has been described as attacking over 1,100 species of plants in 140 families with economic value. The objective of the present study was to investigate, in the laboratory, the reproductive parameters of the predatory mite P. macropilis when fed T. urticae. Experiments were conducted under laboratory conditions at 25 ± 2 °C of temperature, 70 ± 10% RH and 14 hours of photophase. In addition, biological aspects were evaluated and a fertility life table was established. The results of these experiments demonstrated that the longevity of adult female was 27.5 days and adult male was 29.0 days. The population was estimated to increase approximately 27 times (R o ) in mean generation time (T), which was 17.7 days. Lastly, the mite population grew 1.2 times/day (λ) and doubled every 3.7 days (TD).Keywords: agricultural acarology, two-spotted spider mite, fertility life table, biology, biological control. Parâmetros reprodutivos de Phytoseiulus macropilis (Banks)predando Tetranychus urticae Koch (Acari: Phytoseiidae, Tetranychidae) em laboratório ResumoOs ácaros predadores pertencentes à família Phytoseiidae constituem um dos principais inimigos naturais de ácaros fitófagos, o que possibilita o seu uso em controle biológico. Entre as principais espécies destaca-se Phytoseiulus macropilis (Banks, 1904) (Acari: Phytoseiidae). O ácaro Tetranychus urticae Koch, 1836 (Acari: Tetranychidae) é considerado uma das espécies de ácaros-praga mais importantes, atacando mais de 1.100 espécies de plantas em 140 famílias de valor econômico. Este trabalho foi realizado com o objetivo de estudar, em laboratório, os parâmetros reprodutivos do ácaro predador P. macropilis, quando alimentado com T. urticae. Os estudos foram conduzidos em laboratório à temperatura de 25 ± 2 °C, 70 ± 10% de UR e 14 horas de fotofase e foram avaliados os aspectos biológicos e confeccionada a tabela de vida de fertilidade. Foi constatada uma longevidade de 27,5 dias para fêmeas adultas e 29,0 dias para machos. A população foi estimada em aumentar aproximadamente 27 vezes (R o ) no período médio de duração de geração (T) que foi de 17,7 dias. A população do ácaro cresceu 1,2vezes/dia (λ) e dobrou a cada 3,7 dias (TD).Palavras-chave: acarologia agrícola, ácaro-rajado, tabela de vida de fertilidade, biologia, controle biológico.

-The spider mite Tetranychus evansi Baker & Pritchard can cause severe damage to tomato crops. The predatory mite Phytoseiulus longipes Evans was recently reported in association with T. evansi in Uruguaiana, Rio Grande do Sul State, Brazil. The objective of the present study was to evaluate the effects of P. longipes on the population of T. evansi on tomatoes under screenhouse condition. The study consisted on four experiments, in each of which 80 potted plantlets were distributed in two plots of 40 plantlets each. Two weeks later, each plantlet of both plots was infested with eight adult females of T. evansi; one week after, four adult females of P. longipes were released onto each plant of one plot. The population levels of T. evansi and the damage caused by these mites were signifi cantly lower (P ≤ 0.05; linear mixed-effect model) in the plots where P. longipes had been released. The results indicate the potential of this predator as a candidate for classical biological control of T. evansi by inoculative releases on tomato plants.
