Abstract

The coconut tree (Cocos nucifera L.) is a crop of great importance, being planted on almost all continents. In addition to natural problems and incorrect management, the occurrence of insect pests is a challenge for production. Atheloca bondari (coconut moth) is a microlepdopteran that in its young phase feeds on young fruits and can lead to abortion, where currently the only control method used is preventive. With the need for efficient control methods, there is also a need for stabilized creation in the laboratory, so that more research can be carried out. In this context, the present work aimed to develop and adapt a breeding methodology for A. bondari, using artificial and natural diets for multiplication in the laboratory. To this end, the viability of A. bondari caterpillars on different diets was evaluated. The research was carried out in a BOD chamber at 25±1ºC, relative humidity of 70±10% and a 12-hour photoperiod, allocated and made available by the Agricultural and Forestry Entomology Laboratory – LEAF. For the bioassay, a completely randomized design was used, with 20 replications for each treatment, totaling 80 experimental units. The following treatments were used: Natural diet 1 (fragmented coconut), Natural diet 2 (whole new coconut), Artificial diet 1 (coconut-based) and Artificial diet 2 (bean-based). Assessments were carried out weekly. The results were subjected to analysis of variance and the means were compared using the T test at 5% probability. The results obtained show that the Natural 1 and Artificial 1 diets were equally efficient. Therefore, it is concluded that it is possible to create A. bondari in the laboratory using a natural and artificial diet.
