| dc.description.abstract | The present study was carried out to evaluate the insecticidal properties of Drosophyllum lusitanicum (L.) Link, an insectivorous plant that is endemic to the western Iberian Peninsula and northwest Morocco. The insecticidal capacities of extracts from field-grown D. lusitanicum plants were evaluated using contact and feeding bioassays against female adults of Liriomyza trifolii (Burgess), one of the major pests of several floricultural and vegetable crops. In addition, the toxicity of the extract from in vitro cultures of D. lusitanicum was evaluated in contact bioassays. The results showed that extracts of D. lusitanicum have considerable insecticidal potential, particularly through contact application (100% mortality 1 d after treatment). Moreover, extracts from in vitro cultures had similar toxicity to those from field-grown plants. Extracts were analysed by gas chromatography coupled to mass spectrometry (GC-MS). The major constituent was 5-hydroxy-2-methyl-1,4-naphthoquinone (plumbagin), and its level was similar in extracts from field-grown plants (11.0 mg ml–1) and from in vitro cultures (8.2 mg ml–1). Although the results suggest that the insecticidal activity of extracts of D. lusitanicum is probably due to the presence of this naphthoquinone, further detailed research is required to identify other compounds that may be responsible for the activity. | por |
