Potential effect of aromatic plants on insect population and fruit quality in rambutan (Nephelium lappaceum L)
Abstract
Rambutan acreage in the Soconusco, region of Mexico, Chiapas is over 2000 hectares, mostly under monocultural agrosystems based on the high use of external inputs. The experiment was carried out from august 2013 to june 2014 in a four year-old plantation (from planting), located 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 erecta, associated 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 13 481 individuals distributed in 13 orders and 87 families; 32.00 % corresponds to insects associated with Ocimum basilicum, 30.03 % Origanum vulgare, 21.07 % to the control and 16.88 % to Tagetes erecta. Ocimum basilicum had the highest percentage of beneficial insects (2.08 %), O. vulgare (1.15), T. erecta (1.11), the control being lower (0.85 %); however, O vulgare presented the highest number of mealy bugs. In the reproductive phase there are differences in the dates of flowering and anthesis; where, O. basilicum has a precocity of 17 days with respect to the traditional system. The parameters of commercial quality (weight and soluble solids) are improved with the association of aromatic plants, mainly with Tagetes erecta.

El banano, principal producto de exportación en Colombia, presenta muchos retos técnicos como el control de la tortuguilla (Colaspis sp.), causante del 33% de pérdidas económicas; dado que los estándares de calidad no permiten la presencia de residuos químicos presentes en los frutos, se evaluó en un cultivo comercial, del municipio de los Córdobas, el efecto de extractos vegetales en el manejo de la tortuguilla. Se evaluó la severidad del ataque a partir del número de roeduras en frutos y la incidencia en racimos y frutos tratados. Los extractos utilizados fueron salvia Salvia officinalis L., anamú Petiveria alliacea L., albahaca Ocimum basilicum L., ajo Allium sativum L. y ají picante Capsicum annuum asperjados con una bomba tipo jardinera sobre bolsas comerciales de polietileno; dejándose expuestas durante una hora para asegurar la adherencia del producto. Se estableció un diseño completamente al azar con siete tratamientos, tres repeticiones, un testigo relativo (bolsa sin extracto vegetal) y un testigo absoluto (racimos sin embolsar); registrando la severidad del daño causado. Los resultados mostraron que los frutos provenientes de racimos embolsados presentaron menor severidad que los frutos no embolsados y los tratamientos constituidos por bolsas impregnadas con extracto de ajo presentaron menor incidencia y grado de severidad, mostrando una disminución del daño en un 98%. Concluyendo que el extracto de ajó fue el producto repelente que mejor acción mostro al daño de fruto. Los tratamientos donde se aplicó Albaca, Ají, Salvia y Anamú se pudieron determinar una mayor incidencia y daño de fruto.
We studied the volatile composition and sexual morphs of Nephelium lappaceum flowers from two orchards, and investigated the choice behavior of the honey bee, Apis mellifera toward the floral extracts from both locations. Our results showed significant differences in chemical composition and sexual morphs; only the hermaphrodite flowers from the Herradero orchard produced limonene and α-pinene and had longer peduncle and sepal than flowers from the Metapa orchard; on the other hand, the hermaphrodite flowers from the Metapa orchard had longer gynoecium. In the behavioral experiment the extracts from the Herradero orchard seemed to give A. mellifera foragers better cues for orientation to food sources, perhaps due to the presence of limonene and α-pinene, which are absent in the samples from Metapa. Such differences in both orchards could affect pollinator attraction and ultimately seed set and productivity.
This research was carried out in 2014 and 2015 to assess the effects of salicylic acid (SA) (0 and 1 mM) and abscisic acid (ABA) (0 and 50 µM) on essential oil content and yield of ajowan (Carum copticum L.) organs under different irrigation intervals (I 1 , I 2 , I 3 , I 4 : irrigation after 70, 100, 130 and 160 mm evaporation, respectively). Plants were sprayed by SA and ABA at vegetative and reproductive stages. In both years, the biomass of vegetative organs (leaves and stem), flower production and seed yield per unit area of ajowan decreased with decreasing water availability. All organs mass improved by application of ABA and particularly SA. Essential oil percentage of all organs increased, but essence yield decreased as a result of water limitation. Reduction in essential oil yield of ajowan organs due to water stress strongly related with the reduction of individual organ mass under stress. Foliar spray of ABA and especially SA improved the medicinal and commercial value of ajowan under different irrigation intervals by enhancing plant organs biomass and accumulation of more essential oil.
The pink hibiscus mealybug (PHM) Maconellicoccus hirsutus Green is a pest that attacks a variety of crops, have high reproductive capacity and dispersion. The objectives were to determine the annual population fluctuation, define the potential number of generations per year and the risk areas of PHM in Nayarit. The fluctuation of populations was obtained from the monitoring performed for two years with three natural hosts of the pest. To determine the potential of generations, we used temperature data from weather stations in the state primary, heat units' requirements and thresholds for development of the species. Lower populations of PHM rainfall were recorded during August to October; populations were moderate during periods of low temperatures from November to February. The highest average occurred during the rainless period and relatively high temperatures from March to June. In the wild host Acacia sp. ("Rabo de iguana") recorded the highest densities of the pest regarding soursop and teak. Four towns in Nayarit showed the highest reproductive potential to record between 14.4 and 13.2 generations per year. In areas not yet invaded by the plague, it could cause 7.5 to 11 generations per year. The coastal area where agricultural production is concentrated surface was increased risk of PHM.
