| Euseius alatus DeLeon (Acari: Phytoseiidae) é um dos predadores mais comuns em fruteiras no Brasil, alimentando-se de pólen, ácaros e outros pequenos artrópodes. Este predador apresenta ampla distribuição, ocorrendo desde o Rio Grande do Sul até o Ceará. O presente trabalho teve como objetivo avaliar o efeito da temperatura no desenvolvimento e na reprodução de E. alatus e determinar suas exigências térmicas. O estudo foi conduzido a 18, 21, 24, 27, 30 e 33°C, umidade relativa de 70 ± 5% e fotofase de 12h. Nessas temperaturas, o período de ovo-adulto durou 14,0; 8,1; 5,5; 4,9; 3,8 e 3,1 dias, respectivamente. Os estágios de ovo, larva, protoninfa, deutoninfa e período de ovo-adulto apresentaram limiares térmicos de 12,52; 13,85; 14,86;... |

| Life cycle of Tenuipalpus heveae Baker (Acari, Tenuipalpidae) on leaflets from three rubber tree clones. The biological cycle of Tenuipalpus heveae Baker, 1945 (Tenuipalpidae), a potential rubber tree pest mite, was studied by the observation of individuals reared on leaflets of the clones GT 1, PB 235 and RRIM 600, in controlled environmental conditions. Three daily observations were done of 60 eggs on leaflets from each clone in order to verify the development of immature stages and the female oviposition. The fertility life table was constructed based in the collected data. Mites reared on PB 235 had faster rate of development, requiring less time in days, to double its population in number (TD), and had the highest values for egg production, female... |

| The host selection for oviposition by Spodoptera frugiperda (J.E. Smith) among corn, millet, cotton and soybean, and its relationship with the biological characteristics were investigated. Free and non-choice tests for oviposition using plots containing five plants each, from each host in plastic greenhouse, resulted in similar oviposition preference among the host plants. In addition, selected biological characteristics of S. frugiperda were determined in the laboratory with larvae feeding on host leaves, and the combination of leaf and cotton boll. Neonate larvae exhibited low success of colonization on cotton boll compared to the leaves of all other hosts. Spodoptera frugiperda fed only on cotton bolls exhibited longer larval and pupal development, and... |

| Rearing Technique and Biological Traits of Atheloca subrufella (Hulst) (Lepidoptera: Phycitidae) in Coconut Fruits. Larvae of the coconut moth Atheloca subrufella (Hulst) develop in flowers and fruits of coconut, Cocos nucifera, causing precocious abscission of these structures and, hence, yield decrease. This work studied a feasible and suitable rearing technique for A. subrufella using fruits of coconut. We first determined the appropriate density of larvae to be reared per coconut fruit (among two, three, four or five larvae) and later tested the suitability of this rearing technique for three successive generations. The storage of egg and pupal stages during 0, 5, 10 and 20 days was also studied at 12ºC. Based on the fertility life table parameters,... |
