Abstract Given the scarce knowledge available on the biological aspects of the family Chrysopidae fed with phytophagous mites, the present work aims to study the life cycle of the generalist predator, Ceraeochrysa cincta (Schneider) fed with Raoiella indica Hirst, in order to obtain information that will be useful in the integrated management of this pest, which can damage several species of palms. Only 6.4% of the F0 generation fed only R. indica reaches the adult stage. Adults originating from the F0 generation did not exceed the preoviposition period. Adding Sitotroga cerealella (Olivier) eggs to the diet, the F2 generation presented the following results: 23% reached the adult stage, the embryonic period was 6.5 ± 0.5 d. The longest instar (9.3 ± 2.1 d) was 3rd instar. The adult had an average longevity of 81.7 ± 54.9 d. Statistically, there was no significant difference between the survival of females and males (P = 0.351 > 0.05). The preoviposition, oviposition and postoviposition periods were 6.8 ± 0.9, 58.92 ± 8.31 and, 54.85 ± 10.86 d respectively. The average oviposition rate was 2.04 ± 0.91 eggs per day per female. Population statistics Ro = 0.5, T = 128.64 d, rm. = 0.005 and λ = 1.005 indicated poor development of C. cincta using R. indica as primary dam. According to the information obtained, it is concluded that R. indica does not satisfy the nutritional requirements of C. cincta, and as a consequence, needs another food source to complete its biological cycle.

The introduction of exotic species represents a threat to the biodiversity of ecosystems and serious problems for agriculture. The red palm mite, Raoiella indica Hirst 1924 (Acari: Tenuipalpidae) is an exotic pest originating in India (SENASICA 2014). It was first detected on the American continent in the Caribbean on the Island of Martinique in 2004 (Fletchmann and Etienne 2004). Since then, it has been distributed to most of the islands in the region (Fletchmann and Etienne 2004; Rodrigues et al. 2007). In 2008, it invaded Venezuela (Vásquez et al. 2008) and Floria, USA (Peña et al. 2009), and in 2009 reported in Mexico (NAPPO 2009).
