Number of larvae per fruit of 'Paluma' guava subjected (WiO) or not (WoO) to oviposition by fruit flies (Ceratitis capitata) for 24 hours and subsequently treated (WiC) or not (WoC) with biodegradable film of cassava (Manihot esculenta) starch and oil of fennel (Foeniculum vulgare) (CCFO) or basil (Ocimum basilicum) (CCBO) and stored at 10 °C and 15 °C for 20 days and at 23 °C (room temperature) for 10 days. Control (WoO WoC).

... principal components analysis (PCA) was performed for each condition/storage temperature and explained 82.30%, 72.10%, and 72.60% of the variability among the treatments with only two principal components at temperatures of 10 °C, 15 ° C, and 23 °C, respectively. In Table 1, it is possible to observe a description of the contributions of the variables for the first two principal components in each PCA and that, on the other hand, they reflect good overall similarity with the grouped treatments ( Figure 5). Together, the projection of the values of Loading and Score along with the Dendrograms describe the contributions of variables for each group and the overall differences among the different treatments. ...

... was observed that the effect of temperature was paramount on the development of C. capitata, that is, lower temperatures promoted a reduction in the number of larvae, which averaged 3.44, 6.22, and 27.22 units per fruit at temperatures of 10 °C, 15 °C, and 23 °C, respectively, in fruits not treated with coating. Considering that the temperature influences the development speed of the insects because they are poikilothermic (body temperature varies according to the room temperature) (CENTENO; MALDONADO; OLIVA, 2002), it was possible to observe the influence of lower temperatures as the main causative factor of mortality in eggs and larvae of C. capitata present in guava fruits ( Figure 5). For temperatures of 10 °C, 15 °C and 23°C, the application of the coatings decreased by 96.81% and 93.11%, 96.47% and 89.23%, and 96.33% and 94.27% the incidence of larvae for coatings with oils of sweet fennel and basil, respectively. ...

... addition, most larvae found in fruits with coating did not have any mobility, which indicates that they are dead. In the fruits that were not subjected to the oviposition the presence of larvae was not observed, thus indicating that the fruits used in the experiment were free of initial infestation of the pest, with the exception of the control treatment at 23 ºC, which had 0.11 larvae per unit of fruit ( Figure 5). ...
