Abstract

This work aims to describe, quantify and compare the development of immature (egg, larvae, pre-pupae and pupa) of the Actinote brylla species, from ovipositions collected in different points of the Metropolitan Region of Santos (RMBS), São Paulo, Brazil. Also, to establish correlations between the development time of each stage and the accumulated temperature of the period (°C), in order to model the potential number of generations of the species in relation to the global temperature increase. Comparisons will be made of the development of larvae grown in the laboratory with larvae left in the field. The ovipositions will be searched in the host plant Mikania lundiana, in different points of the RMBS during the periods of adult activity. The collected ovipositions will be properly labeled and georeferenced and, in the laboratory, photographed under standardized conditions for egg counting and area estimation occupied by the same. Lab reared larvae will be provided with fresh leaves from the larval food plant and the temperature continuously monitored by a station based on an Arduino Uno microprocessor. Data analysis will be done using appropriate tests in program R. Whenever the data allow, parametric tests and, in some comparisons, multivariate statistics will be used preferably.
