ABSTRACT: The study of non-target organisms such as mites, can provide information about the possible effects of transgenic maize cultivars on the arthropod community. This study aimed to evaluate the abundance of phytophagous mites in the area of Bt maize and evaluate the instantaneous population growth rate, and food preference of phytophagous mites on Bt maize. We registered the species occurrence and the number of adult mite individuals on four maize cultivars, one non-Bt 30F35, and three containing the proteins Cry1Ab (30F35 Yg), Cry1F (30F35 Hx) and Vip3a (Impacto Viptera). Cry proteins disrupt the midgut epithelium of insect pests. The food preference and instantaneous population growth rate (ri) were evaluated using the two-spotted spider mite Tetranychus urticae as model. The species Catarhinus tricholaenae and Aceria zeala were recorded. The Bt maize cultivars did not significantly affect the average number of C. tricholaenae and A. zeala mites compared to conventional cultivar. The population growth rates of T. urticae were similar for the different maize cultivars. T. urticae showed no preference between the leaf of Bt or conventional cultivars. Bt maize did not affect the abundance of species in phytophagous mite. Key words: plant defense, Non-target organisms, Genetically modified organisms Bt protein, Diptilomiopidae, Eriophyidae, Tetranychidae. RESUMO: O estudo de organismos não-alvo, tais como ácaros, pode fornecer informações sobre os possíveis efeitos de cultivares de milho transgênico na comunidade de artrópodos. Este estudo teve como objetivo avaliar a abundância de ácaros fitófagos na área de milho Bt e avaliar a taxa de crescimento populacional instantânea e preferência alimentar de ácaros fitófagos em milho Bt. Registramos a ocorrência de espécies e número de indivíduos adultos de ácaros em quatro cultivares de milho, um não-Bt 30F35, e três contendo a proteína Cry1Ab (30F35 Yg), Cry1F (30F35 Hx) e VIP3A (Impacto Viptera). A preferência alimentar e taxa instantânea de crescimento populacional foram avaliadas utilizando fêmeas adultas do ácaro-rajado Tetranychus urticae. As espécies Catarhinus tricholaenae e Aceria zeala foram registradas. As cultivares de milho Bt não afetaram significativamente o número médio de ácaros C. tricholaenae e A. zeala em relação ao cultivar convencional. As taxas de crescimento populacional de T. urticae foram similares para os diferentes cultivares. T. urticae não mostrou preferência entre a folha de milho Bt ou cultivares convencionais. Sugere-se, então, que o milho Bt não afeta a abundância de espécies, preferência alimentar e taxa de crescimento de ácaros fitófagos.

In the frame of the project ?Conservation and sustainable management of below ground
biodiversity (GEF/UNEP-CIAT/TSBF)? soil organisms inventories were done in the biosphere
reserve of Los Tuxtlas around Santa Martha volcano. 3 Sites (LM, SF and VC) and 4 land use
(forest (S), fallow (A), pasture (P) and maize (M) were sampled, in 89 points . The sampled
organisms were the biological nitrogen fixators, the mychorrizal fungi, the nematodes, the
macrofauna (earthworms, ants, termites, beetles, millipedes, centipedes?). In each point the
samples for the microorganisms and nematodes came from a composite soil sample made of
12 cores of 5 cm diameter and 20 cm height. The macrofauna was sampled with monoliths
(25x25x30cm), Winkler bags and Pitfall traps. Some chemical parameters (pH, Na, K, Mg. Ca
and P Bray), physical (% H,EC, clay, lime, sand, ad, rd, slope) and organic parameters ( C, N,
NH4, NO3, litter and deshydrogenase and B-glucosidase activity) were measured in each points
from the composed sample.
In order to synthesized the results and to evaluate which parameters of the soil determine the
diversity of organisms the general indicator of soil quality (GISQ) was build after 4 subindicators
that evaluates the physical, chemical, organic matter and the macrofauna data. The construction
of the GISQ was made with PCA of each of the 4 sets of variables and a cluster analysis. Also
identification of species indicators (Ind Val) and coinertia analysis was carried out.
The PCA of the 4 set of variables showed significant separation among sites and among land
uses. LM site had the best soil quality, followed by SF and VC. In the land use system S showed
the best soil quality and M the lowest, although in some group of variables P and A uses presented
a quality near to S.
The highest GISQ (1.00-0.85) were from LM but in different land uses (S, A and P); the lowest
(0.49-0.21) were in VC in maize and pasture and in SF in maize. The cluster analysis did
discriminate 8 groups of the sampling points having a similar GISQ.
The Ind Val analysis extracted some species indicators many from the ants and the nematodes
and few from the earthworms, termites and mycorrhizal fungi.
The co-inertia analysis between soil quality indicators and species richness displayed that
some diplopodes and coleoptera and native earthworms required a high soil quality soil. Other
coleoptera, ants and exotic earthworms required a less rich soil although with a high quality in
organic matter. Finally ,the microorganisms (Rhizobia and mycorrhizal fungi), Nematodes and
Chilopoda, were more represented in poor quality soils MenosIn the frame of the project ?Conservation and sustainable management of below ground
