The Mediterranean fruit fly, medfly, Ceratitis capitata (Wiedemann)
(Diptera: Tephritidae) is a serious pest of many fruits and vegetables.
This study was conducted to determine the antifeeding and insecticidal
activities of some essential oils extracted from Pelargonium graveolens
(Geraniaceae), geranium, and Lavandula intermedia Mill. (Lamiaceae),
lavender, Nigella sativa L. (Ranunculaceae) black cumin, and Laurus
nobilis L. (Lauraceae), laurel, against second instars of the Medfly on an
artificial diet. The essential oils were obtained by Clevenger-type water
distillation and a laboratory-reared medfly colony was used in the study.
The doses of each tested essential oil were determined by multiplying
their specific gravities by applying amounts into the diet and then
distributing oil over the diet in a Petri dish having 20 larvae. All
experiments were performed under laboratory conditions of 23±1°C, 50%
RH, and 16: 8 (L:D) photoperiods. Probit MsChart was used to estimate
the LC50 and LC90 values of the tested essential oils. GGE Biplot analyses
were created with the larval mortality based on the different essential oil
doses. As a result, the highest larval mortality was determined with the
addition of laurel and black cumin oils into the diet. The highest mortality
was detected in black cumin oil at the lowest concentrations. Based on
GGE Biplot analyses, the essential oil of black cumin had larvicidal
properties. The results provided fundamental information about the
insecticidal and antifeeding properties of the medfly in the laboratory.
Further studies are needed to integrate sustainable management
programs with natural insecticides against the medfly larvae.
