LEYVA, Maureen; TACORONTE, Juan E; MARQUETTI, María del Carmen  y  MONTADA, Domingo. Insecticidal activity of 3 essential oils from plants on Musca domestica (Diptera: Muscidae). Rev Cubana Med Trop [online]. 2008, vol.60, n.3. ISSN 0375-0760.

BACKGROUND: musca domestica turns into vectors of several diseases by transporting different pathogenic microorganisms in its external morphology and digestive tract. A number of methods has been used to control this species by means of chemical insecticides both adulticides and larvicides, to which resistance has been reported. OBJECTIVES: to evaluate the insecticidal action of 3 essential oil extracts from plants on Musca domestica and to obtain the respective diagnostic doses. METHODS: essential oils from Eugenia melanadenia (Myrtales: Myrtacea); Psidium rotundatum Griseg (Myrtales: Myrtacea) y Piper aduncum (Piperales: Piperacea) were used to determine the potential insecticidal action. The lab bioassays used a strain from a rural area named "Bentre". Several concentrations of each of these oils were prepared to evaluate mortality from 10 to 100 %, by applying 1 µL on Musca domestica thorax according to WHO methodology for insecticide susceptibility tests. RESULTS: Lethal dose values for Eugenia melanadenia were LD50= 0.21 % and LD95= 1.33 %, being the regression line y= 4.82 + 2.05x. Psidium rotundatum oil had LD50= 0.18 and LD95= 2.4 % and its line equation y was 4.92 + 1.49x. Piper aduncum oil showed LD50= 0.04 % and LD95= 0.33 % and its line equation y= 5.19 + 2.10x. CONCLUSIONS: the insecticidal action of these essential oils on M. domestica adult females was confirmed. Diagnostic doses for Eugenia melanadenia (2 µg/insect at 2.88 %); Psidium rotundatum (2 µg/insect at 7 %) and Piper aduncum (2 µg / insect at 0.6 %) were estimated to be used as alternative controlling method in the surveillance of adult Musca domestica populations.
