| O objetivo deste trabalho foi determinar os aspectos biológicos de Harmonia axyridis, alimentada com duas espécies de presas, e a ocorrência de predação intraguilda com Eriopis connexa. Larvas de H. axyridis foram alimentadas diariamente com ovos de Anagasta kuehniella ou com o pulgão Schizaphis graminum. Adultos da joaninha foram separados em dez casais que receberam o mesmo tipo de alimento da fase larval. Na avaliação da predação, uma larva de quarto instar de cada espécie foi mantida na presença ou ausência de abrigo e de ovos de A. kuehniella. A fase larval de H. axyridis durou 10,2 e 8,9 dias, quando alimentada com A. kuehniella e S. graminum, respectivamente. A sobrevivência do predador, em fase imatura, variou de 70 a 100%. A joaninha apresentou... |

| The objective of this work was to evaluate the development, survival, reproductive capacity, and longevity of the Asian ladybug Harmonia axyridis in comparison with Cycloneda sanguinea and Hippodamia convergens. Coccinellid larvae and adults were fed daily with Schizaphis graminum. Ten couples of each species were isolated for evaluation of the adult phase. The duration of the larval stage of H. axyridis is the longest (10.2 days) and its adults are the heaviest (29.7 mg) compared with C. sanguinea and H. convergens. The three species showed similar percentages of survival during the developmental stages. An average of 82% of C. sanguinea, H. axyridis, and H. convergens larvae reached adulthood, which indicates that temperature (25°C) and the offered prey... |

| The objective of this work was to predict the occurrence of alates of Brevicoryne brassicae, Lipaphis erysimi, and Myzus persicae (Hemiptera, Aphididae) in Brassicaceae. The alate aphids were collected in yellow water traps from July 1997 to August 2005. Aphid population peaks were predicted using a degree‑day model. The meteorological factors, temperature, air relative humidity, rainfall, and sunshine hours, were used to provide precision indexes to evaluate the best predictor for the date of the first capture of alate aphids by the traps. The degree‑day model indicated that the peak population of the evaluated aphid species can be predicted using one of the following biofix dates: January 1st, June 1st, and the date of the first capture of the alate... |
