For the entomophagous the similarities is bigger Table 2 ranging between 42 and First of all, the calculated collection curve indicated that the samples taken from onion crop were enough to collect the majority of species present in the crop during the experiment. The reports indicate that the seeds of L.

Cultivo del marigold: efecto en el control de nematodos

This is due to a higher number of T. A similar result was found for the second most abundant species, Therioaphis trifolii Hemiptera: The marigold at the onset of flowering was more attractive ereta sucking phytophagous species, e.

Biological control of insect pests in the Tropics. Thiophene occurrence in different Tagetes species: The marigold strips were also sampled during the period of onion cultivation, and each sample corresponding to one square meter of crop coverage, using the same methodology as for onion plants.

Cultivo del marigold: efecto en el control de nematodos [1982]

Effects of inter-cropping of Tagetes erecta on root-knot disease and growth of tomato. An analysis of variance ANOVA and multiple comparison tests to evaluate differences between the effects of the treatments were used.


Species richness and Shannon’s diversity index were higher at 5 m from marigold.

The results of this study are consistent with previous reports on L. Regarding marigold plants Table 1 we found more richness and abundance of parasitoids compared to onion plants, since those plants produce pollen and nectar that potentially can sustain parasitoid populations Baggen, In general, this species registered the highest values for root length, number of roots and root dry weight among all the species analyzed and in the FCF substrate Tab.

Entomologia Experiementalis et Applicatav. In summary, accession CA of L. Phytophagous insect abundance, however, was greater far from than near to marigold strips, xe Additional studies are necessary to determine the least distance between onion crop and the marigold rows and what is the best width of these rows.

The objective of this study was to evaluate methods of asexual propagation with stem cuttings in the aromatic plant species Lippia origanoides accessions CA and CALippia alba accession CA and Tagetes zypaquirensis accession CA and determine the germination behavior of Tagetes caracasana accession CAin order to contribute to the establishment of these promising aromatics as potential cutlivo crops in Colombia.

The genus Tagetes is native to the New World and the species T. Stock plants were established from seeds collected from mature plants growing wild. However, these plants, as is characteristic of native species that are often found in the wild, lack methods of propagation and agronomic management, which limits their use as potential new crops. Establishment of propagation methods for growing promising aromatic plant species of the Lippia Verbenaceae and Tagetes Asteraceae genera in Colombia.


Tagetes caracasana CA Germination tests were performed for T. The results of this study are similar to other reports in other cuotivo species such as the Atlantic white cedar Chamaecyparis thyoides [L.

Figure 2 compares the overall development of the evaluated accessions of L. Detection of differences among assemblages of marine benthic species based on an assessment of dominance and diversity. The opposite was observed with predators, especially Stomatothrips angustipennisStomatothrips rotundus and Franklinothrips vespiformis Thysanoptera: After a period of eight weeks, the seedlings were transplanted in a greenhouse with plastic cover and grown during a period of at least 32 weeks, after which the plants accumulated enough biomass to provide cuttings.

Germination tests were performed for T. Concluded that as smaller the number of flowers, larger it individual weight, with larger consequent production of petals for flower. Plant odours with potential for a push-pull strategy to control the onion thrips, Thrips tabaci. Direct differentiation of shoot buds in leaf segments of white marigold Tagetes erecta L.

In contrast, the application of hormone promoted the number of roots in the cuttings. Ediciones Mundi Prensa, Madrid. IBA-induced changes in antioxidant enzymes during adventitious rooting in mung vean seedlings:
