ENRIQUEZ, Lucy; CASTILLO, Jorge  and  RODRIGUEZ, Susana. Biology and behavior of Amauromyza Maculosa (Malloch, 1913) (Diptera: Agromyzidae) in artichoke (Cynara Scolimus L.) and sunflower (Helianthus Annus L.). Ecol. apl. [online]. 2014, vol.13, n.2, pp.79-84. ISSN 1726-2216.

In artichoke, the life cycle of Amauromyza maculosa (Malloch) lasted 22.6 days. The egg is endophytic and the incubation period was 2 days; the larval period of the first and second stage was 2 days each and the third stage of 3 days; pupa lasted 11 to 14 days. Oviposition period was 38.8 days, the capacity was 326.6 oviposition eggs and sex ratio (M: F) was 1.1: 1.5. In sunflower, the life cycle takes 19.8 days. The egg, larva first and second stage lasted two days each one, in two generations, and 1 day in the third generation; and third larval stage lasted 3 days in the first and second generation and 2.5 days in the third generation. The pupa lasted 10 to 12 days. Oviposition period was 35.7 days, the oviposition eggs capacity was 345.3 and sex ratio (M: F) was 1: 1.5.
