“…It might be explained by the difference in composition of active principles present in different plant structures since some are non-polar substances that are difficult to extract in water (Delgado and Cuca, 2007;Scott et al, 2008;Camarillo et al, 2009). The toxicity of extracts is also due to a differential concentration of active principles in plant structures, a property that was demonstrated by Weber et al (1994) in Zabrotes subfasciatus (Boheman) and Camarillo et al (2009) in T. vaporariorum, who showed that flower oils of Tagetes minuta and T. filifolia, respectively, were more active than extracts from other parts of the plant because flowers have a greater number of terpenes of low molecular weight, such as trans-anethole or alilanisol. This finding was also noted by Sáez et al (1998) with leaf extract of P. auritum against the fruit fly (Drosophila melanogaster, Meig.…”

In a search for sustainable options of greenhouse whitefly Trialeurodes vaporariorum (Westwood) management, the toxic and/or repellent potential of water, ethanolic, and acetonic extracts of Ambrosia artemisiifolia L. (Asteraceae), Comocladia engleriana Loes (Anacardiaceae), Piper auritum Kunth (Piperaceae), Raphanus raphanistrum L. (Brassicaceae), and Taraxacum officinale F.H. Wigg. aggr.* (Asteraceae) were evaluated. Repellency was assessed by the cylinder method (olfactometer), while toxicity and oviposition inhibition were assessed by the leaf immersion method. Acetonic extracts did not cause any repellent or insecticidal effect. In contrast, 200 mg mL -1 water and ethanolic extracts of R. raphanistrum and ethanolic extract of A. artemisiifolia had the highest repellent activity (76%, 72%, and 69%, respectively) although their activity decreased gradually over time. Ethanolic extracts of P. auritum (66%) and R. raphanistrum (56%) at 200 mg mL -1 were highlighted as being toxic, while the most effective in inhibiting oviposition were water extracts of R. raphanistrum (76.1%) and P. auritum (72.0%) and ethanolic extract of P. auritum (69.5%); however, concentrations lower than 60 mg mL -1 caused oviposition stimulation. Our results suggest that water and ethanolic extracts of R. raphanistrum and P. auritum represent a useful tool in integrated whitefly management.

“…Components: -phelandrene (1), limonene (2), -ocimene (3), dihydrotagetone (4), tagetone (5), cistagetenone (6) and trans-tagetenone (7). Various studies on T. minuta reported that there are variations in the essential oil composition according to the harvesting location (Zygadlo et al, 1993), the growth stage (Moghaddam et al, 2007) the different parts of the plant (Weaver et al, 1994) and the different chemotypes (Gil et al, 2000). All these facts suggest that a deep study of the native T. minuta essential oils is necessary at the regional level.…”

“…Furthermore, T. minuta extracts have also been shown to significantly kill various kinds of insect pests such as stored product beetles (Weaver et al, 1994(Weaver et al, , 1997Keita et al, 2000), mosquitoes (Philogene et al, 1985;Basabose et al, 1997;Perich et al, 1995) and armyworms (Rao et al, 2000;Aldana-Llanos et al, 2012). Most of these studies further identified chemical substances that appear as likely candidates for active compounds responsible for effecting insect mortality.…”

The cabbage aphid, Brevicoryne brassicae is one of the most serious insect pests of cabbage in Lesotho. Chemical insecticides for efficient control of this pest are often unaffordable for resource-poor farmers. As a first step in a search for effective pest management techniques that can be affordable and easily available to these farmers, the aphicidal activities of Tagetes minuta crude extracts were evaluated against the cabbage aphid. A comparison was made on lethal and sub-lethal effects of T. minuta crude extracts from acetone, methanol, water and a mixture of acetone/methanol/water (7:7:1, v:v). The solvent system that produced the most toxic extract was the mixture, followed by methanol and water, whereas acetone produced the least toxic extract. The sub-lethal effect on cabbage aphid fecundity was well described by linear regression equations that showed significant reduction in fecundity as the concentration of crude extracts increased. The extract from the mixture solvent system had the strongest effect on fecundity.
