| Studies on artificial laboratory selections with abamectin, cross-resistance relationships, and stability of resistance were carried out with Tetranychus urticae Koch to provide basic information for an abamectin resistance management program. Selections for resistance and susceptibility to abamectin were performed in a population of T. urticae, collected from a commercial strawberry field in the State of São Paulo, Brazil. After five selections for resistance and five selections for susceptibility, susceptible (S) and resistant (R) strains of T. urticae to abamectin were obtained. The resistance ratio (R/S) at the LC50 reached 342-fold values. The toxicity of eight acaricides was evaluated in the R and S strains, observing significant differences (at... |

| Os Eucoilinae, juntamente com os Opiinae (Braconidae), são os mais importantes parasitóides de larvas frugívoras (Tephritoidea). No sentido de se conhecerem as espécies de eucoilíneos no Brasil, sua distribuição geográfica, hospedeiros associados e percentagem de parasitismo, 170 amostras de parasitóides de 51 municípios das cinco regiões do Brasil foram examinadas. Obtiveram-se 2025 eucoilíneos, dos quais seis espécies (42,82%) estão associadas às larvas frugívoras. Foi possível associar os parasitóides a sete espécies de moscas e a 33 espécies de fruteiras de 15 famílias. Os eucoilíneos são generalistas, parasitando tanto as espécies do gênero Anastrepha (Tephritidae) quanto espécies da família Lonchaeidae. Aganaspis pelleranoi (Brèthes) é a espécie mais... |

| The infesting species and their infestation indices of fruit flies were determined for eleven guava genotypes (Psidium guajava L.). From March to April 2000, ten mature fruits of each genotype were harvested at weekly intervals from insecticide unsprayed trees located in the municipality of Monte Alegre do Sul, SP, Brazil. Fruits were brought to the laboratory, weighed and placed in individual plastic cups containing sand at the bottom to obtain the tephritid pupae. About 95% of guavas produced fruit fly puparia. Of the 682 Anastrepha females recovered, four species were identified: A. fraterculus (Wied.) (86.5%), A. obliqua (Macquart) (10.8%), A. bistrigata Bezzi (1.8%) and A. sororcula Zucchi (0.9%). Three species of parasitoids Braconidae (Opiinae) were... |
