- Abstract
The article presents a study on agricultural pest management service rendered by Brazilian free-tailed bats in transgenic and conventional cotton crops. The study aimed to develop a dynamic model that will predict regional-scale ecological function in agricultural food web through the use of insect pest herbivory indicators measured by cotton damage and insect emigration from cotton. In a research conducted in Texas Winter Garden, the appearance of large numbers of insectivorous bats yielded a summer dispersion of adult pest insects in Bacillus thuringiensis cotton which was decreased from the moth emigration when bats did not appear in either non-transgenic or transgenic crops. The agronomics of the cotton manufacture was more profitable when large numbers of bats were not absent.
