Resumen
Weevils attack is one of the major factors responsible for low
yield of brazilian banana plantations. Among them, there is the banana weevil
Cosmopolites sordidus (Germar, 1824) (Coleoptera:Curculionidae), considered a
major pest of banana, meet up widespread, causing damage in all producing
countries, and Metamasius hemipterus (Linnaeus,1758) (Coleoptera: Curculionidae),
which in recent years has emerged as pest in banana plantation. Periodic monitoring
of the population of these insects contribute to reduce the damage caused in banana
plants, therefore, it becomes the producer to intervene in the management of the
crop before the insect reaches the economic injury level. This present study aimed to
evaluate the efficiency of attractive baits for catching insects of the family
Curculionidae, as well as monitor the population dynamics of C. sordidus and M.
hemipterus on commercial banana plantation cv. Nanicão, in dry and rainy season,
from May 2012 to April 2013, in conditions of the Amazon biome. Three treatments
were used: 1) synthetic aggregation pheromone - as control; 2) sugarcane molasses
and 3) sugarcane pieces, disposed in plots of 0.5 hectare each one. Among the
tested baits, sugarcane molasses and sugarcane pieces were not effective to capture
C. sordidus. However, the attractive bait sugarcane pieces proved efficient for
monitoring and massal collect M. hemipterus in banana plantation. The population
dynamics of C. sordidus, was positively influenced by rainfall, with higher population
levels in the rainy season. Compared to M. hemipterus was observed that the insect
population did not suffer any influence of climatic variables.
