Effect of Weather on Infestation of Buildings by the Invasive Argentine Ant, Linepithema humile (Hymenoptera: Formicidae)

چکیده
—Weekly reports of the abundance of the Argentine ant, Linepithema humile, in 69 households for 18 mo (1/98–7/99) in the San Francisco Bay Area in northern California were compared with weather data. Ant abundance inside homes was highest in cold rainy weather, and there was a second smaller peak of ant abundance in hot dry weather. Pesticide use in the home decreased ant abundance, from one week to the next, only when ant abundance was extremely high.

متن کاملNorthward expansion of the invasive Linepithema humile (Hymenoptera: Formicidae) in the eastern United States is constrained by winter soil temperatures.
The invasive Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae) has been evident in the North Carolina Piedmont, United States for 90 yr but has failed to spread further north. We investigated the mechanisms preventing this expansion. The Argentine ant ceases foraging at temperatures below 5°C and we hypothesized that winter soil temperatures at higher latitudes restricted fora...
متن کاملThe invasive Argentine ant Linepithema humile (Hymenoptera: Formicidae) in Northern California reserves: from foraging behavior to local spread
We review the results from a 20-year study of the spread of the invasive Argentine ant, Linepithema humile (MAYR, 1868), in a reserve in Northern California. Ecological studies show that Argentine ants disrupt native ant communities. The best predictor of Argentine ant distribution is proximity to human disturbance, because buildings and irrigation provide water in the dry season and warm, dry ...

The Argentine ant (Linepithema humile) is recognized as one of the world's most damaging invasive species. One reason for the ecological dominance of introduced Argentine ant populations is their ability to dominate food and habitat resources through the rapid mobilization and recruitment of thousands of workers. More than 30 years ago, studies showed that (Z)-9-hexadecenal strongly attracted A...

Environ. Entomol. 27(4): 822-8.33 (1998) ABSTRACT The Argentine ant, Linepithema humile (Mayr), has spread worldwide, often decimating native ant populations and other arthropod species in invaded areas. It is not known what abiotic and biotic conditions limit its distribution. We investigated the distribution of the Argentine ant in the Jasper Ridge Biological Preserve in northern California, ...
