“…The shortest duration of the larval stage of individuals of T. arnobia that originated males or females on guava leaves agreed with Santos et al (2000) and Holtz et al (2003a). Larval period of caterpillars fed on guava leaves which originated females was also shorter than on E. grandis which has been considered one of the best food sources for T. arnobia (Lemos et al, 1999).…”

-The attack of phytophagous mites may induce plants to produce volatiles, which in turn may attract predators. The occurrence of multiple phytophagous infestations on plants may infl uence predator response. In this paper, we investigated whether the attraction of the predatory mite Phytoseiulus macropilis (Banks) to phytophagous-infested plants would change with the simultaneous presence of two tetranichid mites Oligonychus ilicis (McGregor) and Tetranychus urticae Koch. While the former species is rarely found on strawberry plants and is only occasionally found in association with P. macropilis, the latter is commonly found on strawberry plants and is frequently found in association with P. macropilis. Y-tube olfactometer test assays demonstrated that the predator preferred plants infested with T. urticae, avoided plants infested with O. ilicis, and had no preference for plants infested with both phytophagous mite species. These results indicated that the presence of a non-prey species (O. ilicis) on a given plant can alter the response of the predator to one of its prey (T. urticae). The consequences of the predatory behavior determined in this study on the predator ability to control T. urticae population on strawberry plants are discussed. KEY WORDS: Induced defense, Fragaria, Tetranychus urticae, Oligonychus ilicisThe attack of phytophagous mites to plants may induce the production of plant volatiles, which in turn may attract natural enemies (Dicke et al 1998, Arimura et al 2005.The role of such herbivore-induced plant volatiles (HIPV) on predator attraction has been studied under laboratory (Pallini et al 1997, Takabayashi et al 2000, greenhouse (Janssen 1999, Venzon et al 1999, Holtz et al 2003 and fi eld conditions (De Moraes et al 1998, Drukker et al 2000, Kessler & Baldwin 2001, Heil & Kost 2006. The complexity of these studies increases with the experimental scale. Under natural conditions, for instance, the presence of more than one species of herbivore on the same plant may alter the blend of HIPV and thereby interfere with the response of natural enemies (Vos et al 2001, Shiojiri et al 2002, Moayeri et al 2007.Few studies have investigated the effects of multiple herbivore infestations on natural enemy attraction. Shiojiri et al (2002) found that the parasitoid Cotesia plutellae Kurdjumov (Hymenoptera: Braconidae) prefers odours of cabbage plants infested with its host Plutella xylostella (L.) (Lepidoptera: Plutellidae) alone, to cabbage plants infested with its host and a non-host herbivore species, Pieris rapae (L.) (Lepidoptera: Pieridae). In contrast, parasitism by Cotesia glomerata (L.) (Hymenoptera: Braconidae) was higher on plants infested with these two herbivores than on plants infested with P. rapae (host) alone.Moayeri et al (2007) observed a stronger attraction of the predator Macrolophus caliginosus Wagner (Heteroptera: Miridae) when plants were infested by spider mites and aphids than when plants were infested by only one of these herbivores. They suggested that the attrac...

“…Contudo, quando em altas densidades, os insetos podem mudar de forma expressiva o seu comportamento, e o abandono do habitat de alimentação para um habitat diferente de pupação, para finalização do seu desenvolvimento, poderia ser uma resposta factível que explique o evento registrado neste estudo. Entretanto, existem dados para outras espécies que contrariam esse apontamento: estudos realizados por Holtz et al (2003) em plantas nativas da família Myrtaceae e em Eucalyptus, sobre a taxa de mortalidade da lagarta Thyrinteina arnobia Stoll (Lepidoptera: Geometridae), mostraram que a sua taxa de mortalidade é maior nas plantas nativas. Contudo, os autores afirmam que isso ocorre, possivelmente, devido a mecanismos químicos de defesa que essas plantas possuem e que agem diretamente sobre o herbívoro.…”

-Herbivorous insects may attack eucalyptus causing economic losses. One of these pests is the moth Euselasia apisaon Dahman, a key pest in the basin of middle Rio Doce. Here we studied the survival of pupae of this moth in Eucalypts and in understorey plants and tested the hypotheses: i) live pupae are more abundant in plants of the understorey than in eucalyptus, ii) there is no difference between the abundance of pupae in different plants of the understorey. We sampled three areas cultivated with eucalyptus in Belo Oriente, MG, and samples were taken in five plots each area, getting five branches of each plant and of five eucalyptus trees that bordered the plot. The proportion of live and dead pupae and the mortality rate were estimated. The abundance of live pupae was higher in the understorey and the mortality rate of pupae was the same among different families of plants of the understorey. It is possible the larger available leaf area of understorey plants justify the greater abundance of live pupae in this habitat, however, avoidance of feeding habitat to finish the life cycle is also a possible explanation. Mortality rate in plants of the understorey points to an equal pressure of natural enemies on the pupae. These appointments help us to understand the dynamics of pests in eucalyptus plantations, providing important information to support actions against pests in natural environments. O lepidóptero apresenta cinco estádios larvais, com duração média total de 28 dias (Santos et al 1993). As suas larvas são gregárias, locomovendo-se enfileiradas ou agrupadas em semi-círculos e o seu período de pupa dura cerca de seis dias, ocorrendo no tronco de Eucalyptus ou nas plantas do sub-bosque (Santos et al 1996). Dada a grande voracidade que as lagartas de E. apisaon apresentam (Santos et al 1993), é possível que em surtos da praga as pupas localizadas longe dos sítios de alimentação tenham maior probabilidade de sobrevivência do que as pupas localizadas nos sítios de alimentação. Nessas situações, há maior risco de queda acentuada das folhas de Eucalyptus e consequente exposição das pupas a predadores.A ação de inimigos naturais é importante no controle biológico de pragas (Snyder & Ives 2003 e é possível que ela seja maior em Eucalyptus, sítio de alimentação das lagartas, do que nas plantas do sub-bosque, já que as lagartas representam um montante de recursos concentrado em Eucalyptus. De certo modo, se as lagartas puparem mais frequentemente no sub-bosque, então podese propor que esse habitat representa um refúgio para a sua população (MacArthur 1958), tornando-as menos disponíveis a seus predadores, aumentando, consequentemente, sua taxa de sobrevivência.
