SUMMARY:

Chrysocharis caribea (Bouček) is a hymenopteran present in some countries of
North America, South America and Africa, which parasitize larvae of miner flies such as
Liriomyza sativae (Blanchard). This work aimed to evaluate the basic biology and
establish parameters such as number of descendants, sex ratio, percentage of parasitism
and longevity of males and females performed in the laboratory. The experiments were
conducted in a climate-controlled chamber at 25°C ± 1°C, 70% ± 10% RH and 12:12h
(L:D) photoperiod. The average parasitism throughout the life of the females was 41,55%.
The peak of parasitism was recorded on the 6th day with 59.10% of parasitized larvae. It
was observed that males (24 days) had greater longevity compared to females (19 days).
The number of offspring produced by each female averaged 214.2. The net reproduction
rate (Ro) was 63.38, intrinsic growth rate (Rm) was 0.15, finite rate of increase (λ) was
1.61, mean time of one generation (T) = 19.9 and population doubling time (Td) = 1.47.
Therefore, based on the results obtained, the capacity for reproduction and maintenance
of C. caribea in L. sativae under laboratory conditions is favorable, allowing further
studies on the species.
