Species distribution modeling for wildlife management: Ornamental butterflies in México
Jazmin Jacinto-Padilla,Jose Lopez-Collado,Catalino Jorge Lopez-Collado,Carlos Gilberto García-García 한국응용곤충학회 2017 Journal of Asia-Pacific Entomology Vol.20 No.2
Butterflies are biotic natural resources that have an economic value in different countries because of their aesthetic features. The objective of this paper was to estimate the geographic distribution of 17 species considered of ornamental importance in México. Presence data was compiled from specialized sources and public databases. Distribution maps were generated for each species with MaxEnt, using predictor variables related to temperature and precipitation. A spatial similarity and species diversity analysis was applied to group the species based on their geographic distribution. The distribution models were considered appropriate based on the Area Under the Curve, which ranged from 0.75 to 0.94 computed with independent data. Three geographic groups were identified; the first group had the largest coverage (% of national area) and comprised the species Pyrisitia proterpia (59%), Danaus gilippus (70%) and Zerene cesonia (72%). The second group ranged in coverage from 23% (Archaeoprepona demophon) to 50% (Anteos maerula), while the third group had the smallest coverage, ranging from 17% to 40%. Overall, the species diversity presents a latitudinal gradient, increasing from the north to the southern, Neotropical part of México. States with the highest species potential are Veracruz, Tabasco, Colima, Michoacán, Guerrero, Chiapas, Oaxaca, and most of the Yucatan peninsula. The application of these results to use butterflies to make souvenirs and as components of ecotourism is discussed.

Studies to determine the population fluctuation of Diaphorina citri, vector of Candidatus Liberibacter sp., have been carried out mainly in commercial plantations, whereas less have focused in urban areas and their synchrony. The objectives of this work were to monitor D. citri adult populations in Murraya paniculata (OJ) in urban areas and in Persian lime (LM) orchards, to estimate the effect of some environmental factors and to evaluate the synchronization between these populations. Sampling was performed from September 2012 to August 2014 in Veracruz, México. Five urban areas and five commercial Persian lime plots close to each other were selected. Adult D. citri catches were made monthly with yellow traps. Vegetative shoots, temperature and relative humidity were measured throughout the sampling period. Adults of Diaphorina citri were captured in all the sampling sites throughout the two-years sampling period and the populations were more abundant in summer. Significant factors affecting trap catches were the presence of new shoots and temperature. Temperature and relative humidity enclosed a comfort zone between 26 and 28 °C and 75 to 85% respectively. Cross-correlation values were positive across hosts within the same locations and between locations, regardless of the distance, thus suggesting a spatial synchronization in trap catches. This spatial relationship represents a risk of infestation between host species because of the potential movement and dispersal

Avocado production in Mexico represents an income of more than $3.2 billion dollars per year in foreign ex change. Unfortunately, several factors can limit the export of this fruit. One of such limiting factor is the avocado seed moth, Stenoma catenifer; however, its population dynamics is barely known. Therefore, is relevant to study the environmental factors affecting population changes, aimed to improve its management. In this study, we monitored the population fluctuations of S. catenifer males and explored its relationship with temperature and relative humidity by using pheromone-baited traps in Hass avocado orchards in the state of Colima, Mexico. From June 2018 to June 2019, a total of 6,836 males of the avocado seed moth were collected, with two population peaks. The first in June-August, during the fruiting stage, and the second in December-January, coinciding with the end of fruiting and flowering stages. Fruit infestation ranged from 0.0 to 65.0% in the or chards examined. Cluster analysis and principal coordinate analysis indicated that sampling time and relative humidity group together but differ from temperature. The effect of relative humidity and temperature on catches was analyzed by relating non-parametric bivariate distributions. The highest male catches were recorded at temperatures greater than 15.8 ◦ C and relative humidity greater than 60% while low relative humidity did not favor moth catches. These results may be useful to predict bioecological conditions for the occurrence of pop ulations of this pest.
