Vegetable’s alimentary consumation has increased not just by the increase of population levels, but also by the recent change of habits on consumer’s nourishment, wich takes the production to increase too. Besides, these products’ consumer became even more exigent, leading to the necessity of quality and amount guided production. The ecologic based production system have several ways inside the agriculture, based on the Agroecology’s statements. Inside this context, we can detach the biodynamic agriculture, developed by Rudolf Steiner in 1924, to value the astronomic rhytms, specially moon’s and constellation’s, applied to agriculture. This work hás been guided to evaluate the interrelation ship of insects on lettuce and rocket cultivation, by the Biodynamic Agriculture Brazilian Association’s Astronomic Calendar (Thun, 2015). The experiment hás been guided with entirelly casual lineation on a factorial plan. We used two factors in order to evaluate: cultivation with the calendar’s statements (C/R) and cultivation without calendar’s statements (C/S), lettuc (a) and rocket (r). This way, we have four treatments: C/Ra; C/Rr; C/Ra, C/Sr. On each portion, 10 repetition with 4plants/repetition, wich totallize 40 plants on the treatments. The appearing insects have been quantified and qualified. These results have been analysed by the F test and compared by the Scott-knott test. Rocket hás not been infested by leafminers, and lettuce has not bben infested by grrenfly. Rocket in the treatment C/Sr showed higher levels of greenfly’s population than C/Rr. Lettuce in the treatment C/Ra has not presented agricultural plagues’ attack, but in the C/As treatment has been injured by leafminers and grasshopper. This way, using the calendar leads to a better management of plagues inside the biodynamic/organic agriculture. The recommendation helps to reduce the injuries, leading to a better control of insects and plagues.
