Potential effect of aromatic plants on insect population and fruit quality in rambutan Nephelium lappaceum L. Francisco Javier Marroquín-Agreda 1. Ernesto Toledo-Toledo 1. CP Rambutan acreage in the Soconusco, region of Mexico, Chiapas is over hectares, mostly under monocultural agrosystems based on the high use of external inputs.

The experiment was carried out from august to june in a four year-old plantation from plantinglocated in the Huixtla municipality, Chiapas; with the objective of evaluating the allelopathic and attractive potential of aromatic plants on the entomofauna and commercial quality of rambutan, three plant species were evaluated: Origanum vulgare, Ocimum basilicum and Tagetes erectaassociated with the cultivation of rambutan; under an experimental design in random blocks with four treatments and five repetitions where indicators of abundance, food habit of insects and quality of fruits of rambutan were measured.

The results showed that the aromatic plants increase the abundance of insects, with a total of 13 individuals distributed in 13 orders and 87 families; Ocimum basilicum had the highest percentage of beneficial insects 2. In the reproductive phase there are differences in the dates of flowering and anthesis; where, O. The parameters of commercial quality weight and soluble solids are improved with the association of aromatic plants, mainly with Tagetes erecta.

The rambutan Nephelium lappaceum L. The Soconusco, Chiapas, emphasizes to overcome the ha 2surface that is distributed in producers of this exotic fruit; being thus the backyard horticultural system and the economic pillar of numerous family nuclei. However, production methods and techniques are based on decisions of chemical control and under a monoculture structure; which favors the deterioration of the productivity and quality of the fruit, in addition to the incidence of insects, such as the case of the mealybug Planococcus lilacinus hemiptera of the insect class, considered a pest; however, the United States of North America has this pest in quarantine, thereby affecting the export of fruits to countries such as Japan 3.

In the face of agroproductive deterioration, the incidence of pests in fruit orchards and the promising results of Tagetes erecta on the growth and quality of Cedrela odorata ; the association of aromatic species such as oregano Origanum vulgarebasil Ocinum basilicum what bugs eat mealybugs dead flower Tagetes erecta could offer a potential in allelopathy of pests and attractants of pollinating insects, or as plant breeders in quality or floral inductor of fruit species 4.

Given this premise, the present work focuses its objectives on the evaluation of the allelopathic and attractive potential of aromatic plants on the entomofauna and commercial quality of rambutan. The investigation was carried out during the productive period August - Junein a plot cultivated with rambutan of four years of established, with distancing of 10x10 m. Rainfall ranges between 2. The predominant soils are of the cambisol type, with a light loam-silty texture.

During the experiment the individual interactions of three species of aromatic plants Origanum vulgareOcimum basilicum and Tagetes erecta associated with a system of rambutan production were evaluated, all of them in comparison with the control without association. The spatial arrangement of the aromatic species was in contour grooves to the outer limit of the drip area of the rambutan trees, with a distance of 40 cm between rows and 30 cm between plants.

For the capture of the insects, an entomological net of 50 cm diameter was used, 10 double hits of the net were made, five on the aromatic plants and five on the rambutan trees, during the period November - June flowering of rambutan. The classification was carried out in the biology laboratory of the Faculty of Agricultural Sciences of the Autonomous University of Chiapas, with the support of a binocular digital stereoscope model ED and taxonomic keys 5based on a guide of beneficial insects.

The what bugs eat mealybugs were analyzed with the statistical software Statgraphics centurion version XVI. Abundance of insects refers to the wealth of individuals that present themselves in a defined spatio-temporal dimension, resulting from the set of interactions between species that are integrated. The total insect abundance accumulated during the development of the experiment was 13 individuals in an area of 4 m 2 ; according to the statistical analysis and the Tukey test. The associations with the highest total abundance were O.

Figure 1 Abundance of insects in a rambutan orchard what bugs eat mealybugs interspersed aromatic species. The fluctuations of the abundance of insects associated with aromatic plants, is based on being a source of nectar, pollen, biomass and secondary metabolites that act as attractant or repellent of individuals of the insect class, mainly of the orders Diptera, Coleoptera and Hemiptera. Therefore, T. However, the volatile properties of O. Similar studies found the presence of 18 families and 22 species associated with O vulgaresome feeding on stems and leaves and others on the plant without defining what are the algebraic terms relationship with it.

Tetraniquids or red spiders Tetranychidae were the most abundant, followed by two species of ants Formicidae and one species of grasshopper Orthopteraas well as the bug Fulvios sp Miridaewhich feeds on coleopteran larvae 9. The population of insects associated with the inflorescence of rambutan was divided into three groups: phytophages, natural enemies and pollinators.

Among the phytophages, the Formicidae family was more abundantly and frequently observed, and less frequently, the families Cicadadellidae, Membracidae, Cercopidae, Otitidae, Droshophilidae, Brentidae, Staphylinidae. Among the natural enemies collected are the family Therevidae, Sphecidae, Culicidae, Termitidae, Reduviidae and Chysopidae The which of the following best explains the relationship between correlation and causation in order of importance were: Apidae and Vespidae.

However, in the agroecosystem rambutan-aromatic plants, the phytophages with the greatest abundance were the Formicidae family, which were found on the aromatic plants causing defoliation. Insects of parasitoid habits and predators include the families Sirphydae, Culicidae, Vespidae, Braconidae, Pteromalidae, Tachinidae and Muscidae. The pollinators in order of importance were: Apidae and Syrphidae. Some authors report that the Vespidae family can be a pollinating insect and others as a predator From the total of insects collected 13the grouped ones according to their activity associated with the agroecosystem rambutan represent The mealybugs Planococcus lilacinus are insects what bugs eat mealybugs the family Pseudococcidae, belongs to Hemiptera order, limiting the commercialization of diverse crops and fruits.

It is what bugs eat mealybugs cosmopolitan pests and in Mexico it is considered of cuarentenary importance During the development of this research, this pest was presented in the stages of development and maturity of rambutan fruits, however, the percentage of infesting Table 1was higher in O. Furthermore, O. Table 1 Infestation of mealybug in rambutan fruits in association with aromatic plants. The reproductive cycle of rambutan for the coast of Soconusco, Chiapas fluctuates from to days, the flowering what bugs eat mealybugs is comprised between the months of January - April and what bugs eat mealybugs harvest period June - July.

Likewise, for other countries such as Honduras and Costa Rica, the cycle of this exotic fruit varies from to days. The early production May of rambutan what does no ons mean on tinder acquire high prices, causing the quality of the fruit to deteriorate due to the immature green fruit harvests. Based on the results of the research, the flowering of rambutan in the associations with O.

Being the witness with what bugs eat mealybugs largest number of days from flowering DFF until the commercial maturity of the fruits with DFF, following T. According to some researchers 14one of the responsible for this event is salicylic acid, secondary metabolites best studied in terms of its natural distribution and function, this simple phenol is present in the reproductive structures and leaves of aromatic species employed in agriculture like those used for this work.

This acid induces flowering, participates in the regulation of cell membrane potential and the resistance of diseases There are reports that mention the effect of salicylic acid in the induction of flowering of the chrysanthemum, 37 days after transplantation DAT compared to the control where it occurred at 43 DAT. Likewise, salicylic acid reduces the synthesis of ethylene and in some species this causes a delay in the senescence of flowers or induction of flowering 16as is the case of O.

According to other authors 17the cultivation of rambutan is cultivated in zones ranging from 0 to m a. The rambutan is a non-climacteric fruit, which is what bugs eat mealybugs the fruit must be harvested when it has reached the optimum conditions of edible quality and visual appearance. According to the results obtained in the association of aromatic plants in contour to the area of trickling of rambutan trees, it was observed that T.

Likewise, a study on entomophilous pollination and thinning of fruits in rambutan, mention that the free pollination of rambutan influences the fruit weight 25 gfollowed by the treatment of fruit thinning with In the same way, the mooring of fruits was greater with the free pollination 7. Table 2 Parameters of quality of fruits of rambutan with association of aromatic plants. The associations with O. They are excellent plants for the attraction of formicids, insects considered as phytophagous what bugs eat mealybugs what is the basic difference between anatomy and physiology the inflorescence of the rambutan; however, O.
