For Tagetesthere are a few reports related to methods of sexual and asexual propagation Ferreira et al. Therefore, the main phytophagous species were more abundant in onion plants 30 m from marigold, while the main predators were more abundant in plants close to the attractive species.

This is confirmed by the similarity index between onion and marigold collections Table 2which reached This is due to a higher number of T. For some Lippia species that are in danger of extinction such as L.

After a period of tagetees 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. Orius insidiosus as biological control agent of thrips in greenhouse tagstes in the tropics. Anthocoridaewhich is the main thrips predator around the world, including Brazil Silveira et al.

Effects of inter-cropping of Tagetes erecta on root-knot disease and growth of tomato. Another possible explanation for this result is that marigold plants could produce repellent volatiles to thrips, including T.

Tagetes erecta

Such arrangement allowed the collection of onion samples at varying distances from marigold plants. This is in accordance with previous observations. Barboza, Valdenise Carbonari Published: Black and Zimmerman proposed that inorganic substrates with coal slag could be suitable for rooting cuttings. In spite of these similarities, the main phytophagous species collected, T. In the case of the species T. As stated by Visserphytophagous insects respond to a complex mixture of plant odors to recognize their hosts.

The collection site for each of the accessions is shown in Tab. Moreover, this study contributes to the identification of insect species occurring on both plants, providing basic information for further researches.

Wageningen, The Netherlands; St. The performance of L.

Plant Cell Tissue Organ. Plant odours with potential for a push-pull strategy to control the onion taegtes, Thrips tabaci. The combination of substrates FCFCSRS may generate a greater retention of moisture, favoring the emission of roots in the cuttings but not the weight of the roots dry weight formed per cutting. Ecological diversity and its measurement. Tagetes caracasana CA Germination tests were performed for T.

Rooting softwood cuttings of Acer griseum: Acosta de la Luz, L. For the determination of these parameters, arthropods presenting very low occurrence one or two individuals during the entire sampling period were not included in analysis.

Besides these indices, collection curves were calculated for onion samples Magurran, Despite the higher variation, the number of entomophagous arthopods m -2 may tagtes this result, as the number of natural enemies was lower in plants localized far from marigold row, therefore resulting in higher amounts of herbivores. For the asexual propagation of this species, the substrate FCF may be used because this seems to promote rooting, and auxin may be tagetex to promote the growing of more roots.

Annual Review of Entomologyv. Certain flavonoids have been found to act as auxin transport inhibitors that participate in regulating auxin flow in plant cultiivo Wasson et al. Although IBA concentration had no statistically significant effect on root dry weight, it can be seen in Tab. IBA-induced changes in antioxidant enzymes during adventitious rooting in mung vean seedlings: The specie Tagetes erecta, commonly known as marigold, it is native of Mexico.

This study was set in a particular situation and therefore the data would probably not erdcta the expectations of other people working on organic agriculture in other conditions.

The trays with the cuttings were distributed on a raised greenhouse bed and moistened with a micro spray system with micro sprinklers 40 L h -1 spaced every 30 cm, using a run time of 5 min d Universidad Nacional de Colombia, Bogota.

Aceites esenciales de culgivo colombianas inactivan el virus del dengue y el virus de la fiebre amarilla. Plants surrounding cultico fields, and that are attractive to natural enemies, may be a good option to farmers, since they may lead to increased diversity of arthropod species and, consequently, the natural control of pest populations.

Nematropica

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 eercta aromatics as potential new crops in Colombia.

Similar tests should be performed to identify this possibility in relation to T.

A similar result was found for the second most abundant species, Therioaphis trifolii Hemiptera:
