Follow this and additional works at: In rural areas of Mexico, the native “escamolera” ant (Liometopum apiculatum Mayr) is socioeconomically important. However, this ant is being exploited.

Liometopum apiculatum

Data were analyzed with stepwise logistic regression, correspondence analysis, Chi-square and simultaneous Bonferroni confidence intervals analyses, and the minimum Akaike Information Criteria.

Given the importance of insects as components of desert ecosystems Hithford et al.

This suggested the palms, with their infestations of scale apicuulatum, provided a rich source of honeydew. Habitat fragmentation of the soil biota and its effects on the density of the micro-invertebrates are poorly documented Chust et al. Colony foundation behavior is not uniform among founding queens.

After laying her first batch of eggs, the queen delays laying more until the first eggs have developed into pupae. The uses of Mesquite Prosopis spp. Liometopum apiculatum queens are among the largest North America ants.

A slightly disturbedB moderately disturbed and C highly disturbed. In addition, the ant avoided very low elevation habitats masl. Light yellow-brown to dark brown with an abundance of short erect to appressed hairs. Particularly, it was observed a large population of nitrogen-fixing bacteria, which could be linked with the high protein content in escamoles. The significant association of the escamolera ant in central Mexico with the agave Agave salmiana Otto Ex Salm ssp.


Immature stages of reproductives have been found in L. Workers are highly excitable and when a colony or nest fragment is disturbed they burst forth, emitting a noxious alarm pheromone, and quickly swarm upon any unwitting myrmecologists found near the nest. University of California publications in Entomology. In some cases these cavities will contain numerous workers, but no brood, and digging reveals there are no additional nest chambers nearby.

Workers are polymorphic with the largest individuals approaching the size of small Formica workers. Mackay and Mackay – This species nests under stones and in trunks of living and dead trees especially oaks and dead Yucca limoetopum. Mackay and Mackay There were significant differences in the observed and expected frequencies for the variables vegetation type, slope of the terrain, aspect and elevation Table 6.

The most abundant Phylum identified by sequencing in the larvae was Firmicutes while in adult ants was Proteobacteria. The quantified variables and methods of their assessment are described in Table 1. A few of the latter are putatively obligate as they are only known from their nest association with this ant. In concert with this apicupatum, workers have been observed successfully soliciting food from of Pogonomyrmex barbatusCamponotus sayi and Apoculatum xyloni foragers.


Today the market demand for brood can be so high that local ant populations of this species are reduced by over-collecting.

When the main section of the nest is found, or suspected to be located, it may be situated in a tree bole or under a large rock. However, the last estimate is incredibly short for a queen, so either these ants are apkculatum polygynous or they live much longer in the wild. However, after prolonged periods two months or more of low temperatures, the larger workers are faster than the small workers.

In the case of Opuntia imbricataLiometopum apiculatum provides protective services to the plant. Insects as human food: This page was last edited on 13 June liometkpum, at Habitat use by the “Escamolera” ant Liometopum apiculatum Mayr in central Mexico.

In the higher elevations of the ejido there are oak forests Quercus hintoniorum, Q. The density of nests in liometophm disturbance level A was 6. In concert with this behavior, workers have been observed successfully soliciting food from of Pogonomyrmex barbatusCamponotus sayi and Solenopsis xyloni foragers. If disturbed in the field, these ants will emit a strong noxious odor.
