| ABSTRACT Lobiopa insularis is one of the main pests of strawberry crop, causing direct damage to fruit, making them unfeasible for consumption and commercialization. This study aimed to estimate, under laboratory conditions, base temperature and thermal requirements of the eggs, larvae, pupae and the biological cycle (from egg to adult) of L. insularis. Insects were reared on artificial diet based on strawberry fruits, at temperatures of 16, 19, 22, 25, 28 and 31°C, using air-conditioned chambers (70±10% R.H.; 12 h photophase). The number of annual generations of L. insularis was estimated for eight municipalities belonging to the main strawberry growing regions in Brazil, considering base temperature and thermal constant. Development time of L. insularis... |

| Abstract: The objective of this work was to prepare a prediction model for the phenology of grapevine cultivars (Bordô, Cabernet Sauvignon, Moscato Embrapa, Paulsen 1103, SO4, and IAC 572) using hot water treatment. The heat treatment with hot water consisted of combinations of three temperatures (50, 53, and 55°C) and three time periods (30, 45, and 60 min), with or without previous hydration for 30 min. After the treatments, the cuttings were planted in the field and their phenological development was evaluated during two months. The six studied cultivars presented different responses to the effects of the factors temperature and time, but did not differ significantly regarding hydration. It was possible to develop a mathematical model for the use of hot... |
