The coccinellids Eriopis connexa (Germar), Harmonia axyridis (Pallas) and Olla v-nigrum (Mulsant) are important natural biological control agents. The purpose of this paper was to study the biology and create a fertility life table of these three coccinellid species. For the biology study, 50 insects/species were used and kept in groups of 10 in glass vials (2300cm 3 ). For the three species studied, the viability of the total cycle varied from 45 to 50%. O. v-nigrum was the species which presented the longest oviposition period. However, H. axiridis demonstrated the best reproductive performance and ability of population growth in each generation. In conclusion, the use of commercially obtained pollen and A. kuenhiella eggs enables the development of coccinellids E. connexa, H. axyridis and O. v-nigrum under laboratory conditions, since the insects completed their biological cycle and originated adults with good reproductive performance.

Resumo -O objetivo deste trabalho foi avaliar o desenvolvimento de estágios imaturos e parâmetros reprodutivos de adultos de Grapholita molesta em dietas naturais, constituídas de ramos e frutos de pessegueiro 'Vanguarda', frutos de macieira 'Gala' e 'Fuji', e em dieta artificial à base de milho. O delineamento experimental foi inteiramente casualizado. Considerou-se cada inseto uma repetição e, no estudo dos parâmetros biológicos dos adultos, cada casal foi considerado uma repetição. Foi calculada a tabela de vida de fertilidade. O tempo para o desenvolvimento das lagartas foi menor em ramos e frutos do pessegueiro, em comparação a frutos de macieira e dieta à base de farinha de milho. Quanto à sobrevivência das larvas, não houve diferença entre as dietas. Com base na tabela de vida de fertilidade, os frutos da cultivar Fuji foram mais adequados ao desenvolvimento de G. molesta do que os da Gala. Os ramos de pessegueiro foram mais adequados ao desenvolvimento do inseto do que os frutos. A dieta à base de farinha de milho foi adequada para a criação dos insetos em laboratório. As dietas avaliadas afetam a taxa de sobrevivência, o desenvolvimento e o potencial de crescimento populacional de G. molesta.

Development and reproduction of the oriental fruit moth in apple and peachesAbstract -The objective of this work was to evaluate the immature stages development and the reproductive parameters of Grapholita molesta adults reared on shoots and fruit of 'Vanguarda' peach, on fruit of 'Gala' and 'Fuji' apples, and on a diet formulated with corn meal. The experimental design was completely randomized. Each insect was considered one replicate; and for the biological parameters of adults study, each couple was considered a replicate. The fertility life table was calculated. The time for larvae development was shorter in peach shoots and fruits, in comparison with apple fruit and corn meal diets. There were no differences for larvae survival, in the comparison between diets. Based on fertility life table, 'Fuji' apple fruit are more appropriated to the G. molesta development than Gala ones. Peach shoots were more suited for insect development than fruit. The corn meal-based diet is suitable to rear G. molesta in laboratory. The evaluated diets affect survival rate, development and growth potential of G. molesta population.

Resumo -O objetivo deste trabalho foi descrever a biologia de Anastrepha fraterculus em frutos de mirtilo (Vaccinium ashei), amoreira-preta (Rubus spp.), araçazeiro (Psidium cattleyanum) e pitangueira (Eugenia uniflora). O experimento foi realizado em laboratório, em condições controladas de temperatura (25±2ºC), umidade relativa (70±10%) e fotófase (12 horas), para determinação dos parâmetros biológicos do inseto nos estágios de desenvolvimento imaturos e adultos. Anastrepha fraterculus completa o ciclo biológico em todos hospedeiros estudados, embora os frutos nativos (pitanga e araçá) ofereçam melhores condições para seu desenvolvimento. Os parâmetros biológicos determinados para as fases imaturas foram semelhantes nos quatro hospedeiros. Insetos criados em pitanga e araçá apresentam, na fase adulta, maior período de oviposição, fecundidade e longevidade de fêmeas, em comparação aos criados em mirtilo e amora-preta. O ritmo diário de oviposição é mais prolongado e uniforme nos insetos criados em araçá e pitanga, o que mostra que A. fraterculus está mais bem adaptada a estas frutas, nativas da região Sul.Termos para indexação: Anastrepha fraterculus, Rubus, Vaccinium ashei, desenvolvimento larval, frutas nativas, pequenas frutas. Biology of South American fruit fly in blueberry, blackberry, strawberry guava, and Surinam cherry cropsAbstract -The objective of this work was to describe the biology of Anastrepha fraterculus in blueberry (Vaccinium ashei), blackberry (Rubus spp.), strawberry guava (Psidium cattleyanum) and Surinam cherry (Eugenia uniflora) fruits. The experiment was carried out in laboratory under controlled conditions of temperature (25±2ºC), relative humidity (70±10%), and photophase (12 hours) to determine insect biological parameters in immature and adult development stages. Anastrepha fraterculus finishes its biological cycle in all studied hosts; however, the Brazilian native fruits (strawberry guava and Surinam cherry) provide better conditions for development of the insect. Biological parameters determined for immature development stadium were similar in the four hosts. Insects reared in Surinam cherry and strawberry guava showed, in the adult phase, longer oviposition period, higher fecundity, and higher female longevity in comparison to insects reared in blueberry and blackberry. Oviposition daily rhythm is longer and more uniform in insects reared in strawberry guava and Surinam cherry fruits, which shows that A. fraterculus is better adapted to native fruits from Southern Brazil.

The increased cultivation of olive trees in Rio Grande do Sul State and its potential production arouse the need to characterize the assemblage of insects in olive groves, especially those with potential as pests. Therefore, the insect fauna was sampled monthly for two years, in the canopy of olive trees, using beat cloth, and collection of buds in five municipalities in Southern Rio Grande do Sul State. The faunal indices analyzed were abundance, constancy, dominance and frequency. The olive caterpillar Palpita forficifera Munroe 1959 (Lepidoptera: Pyralidae) and mealybugs Saissetia oleae (Olivier, 1791) and Saissetia coffeae (Walker, 1952) (Hemiptera: Coccidae) are the main phytophagous insects in olive farms in the Rio Grande do Sul State, with potential to reach pest status. Eleven insect species were recorded for the first time in olive groves in Brazil. The occurrence of P. forficifera is a new record for the Rio Grande do Sul State.
