“…A associação positiva com maior valor foi entre Tarsonemidae e Tydeidae (0,534) (Tabela 2) e isso pode estar ligado ao fato de esses ácaros compartilharem, comumente, o mesmo hábito alimentar, que inclui a ingestão de fungos (Hughes 1976, Sinha 1979. Os ácaros da família Tarsonemidae, principalmente a espécie T. granarius, e os da família Tydeidae são associados com fungos dos gêneros Penicillium, Aspergillus, Chaetomium e Hormodendrum e com outros ácaros (Hughes 1976).…”

“…Colunas seguidas pela mesma letra, dentro de cada grupo de ácaros, não diferem estatisticamente (P > 0,05). nos depósitos, dentre outros fatores, podem favorecer o desenvolvimento de ácaros (Sinha 1979, Lorini 1998. Segundo Mercado et al (2001), temperatura de 26ºC e umidade relativa de 86% podem ser consideradas ótimas para o desenvolvimento de S. medanensis, comum em primárias, S. medanensis foi a mais abundante neste levantamento, portanto, provavelmente, é uma das fontes de alimento de C. malaccensis em ambientes de armazenamento nas condições da cidade do Recife, PE.…”

-The mite fauna was assessed in bean, maize and pet food in supermarkets and markets in Recife, PE, Brazil. A 500 g sample of each grain and food was collected in each establishment at two weekly intervals, from August 2002 to June 2003. The sample was divided into two 250 g subsamples. One of them was submitted to spider mite evaluation shortly after collection and the other was incubated at 26 o C and 78% humidity for 30 days. At the end of this period the second subsample was processed in the same way as the first. The spider mites were mounted on slides for microscopy in Hoyer medium and identified at least at genus level. Eleven thousand nine hundred and fifty-six spider mites were collected belonging to the Acaridae, Ebertiidae, Glycyphagidae, Cheyletidae, Stigmaeidae, Pyemotidae, Tarsonemidae, Tydeidae, Cunaxidae, Ameroseiidae, Ascidae e Phytoseiidae families. Among the primary spider mites the Suidasia medanensis Oudemans species was predominant in the survey (3,035 individuals) followed by Caloglyphus hughesi (Samsinak) (436 individuals). Metapronematus sp. was predominant (3,417 individuals) among the secondary spider mites followed by Tarsonemus granarius Lindquist (3,003). The number of mites collected in the incubated samples was always greater compared to the non-incubated samples in both the market and supermarket samples.KEY WORDS: Acari, stored product, diversity RESUMO -Este trabalho teve como objetivo avaliar a acarofauna em grãos de feijão, milho e ração em supermercados e feiras livres da cidade do Recife, PE. Em cada estabelecimento foi coletada uma amostra de 500 g de cada grão e ração, em intervalos bimensais, no período de agosto/2002 a junho/ 2003. Cada amostra foi dividida em duas sub-amostras de 250 g. Uma delas foi submetida à extração de ácaros logo após a coleta e a outra foi incubada a 26 o C e umidade relativa de 78% por 30 dias. Ao final desse período a segunda sub-amostra foi processada da mesma forma que a primeira. Os ácaros foram montados em lâminas para microscopia em meio de Hoyer e identificados pelo menos até o nível de gênero. Foram coletados 11.956 ácaros pertencentes às famílias Acaridae, Ebertiidae, Glycyphagidae, Cheyletidae, Stigmaeidae, Pyemotidae, Tarsonemidae, Tydeidae, Cunaxidae, Ameroseiidae, Ascidae e Phytoseiidae. Dentre os ácaros primários, a espécie Suidasia medanensis Oudemans foi a predominante no levantamento (3.035 indivíduos), seguida de Caloglyphus hughesi (Samsinak) (436 indivíduos). Metapronematus sp. foi predominante (3.417 indivíduos), dentre os ácaros secundários, seguido de Tarsonemus granarius Lindquist (3.003). O número de ácaros coletados nas amostras incubadas foi sempre superior em relação às amostras não incubadas, assim como nas amostras de feira livre em relação às de supermercado. PALAVRAS-CHAVE: Acari, grãos armazenados, diversidade O ambiente artificial criado pelos depósitos e armazéns de grãos armazenados favorece o desenvolvimento de diversas espécies de ácaros, visto que a proteção contra extremos de temperatura permite ...

“…Stored grain can vary in quality due to biotic and abiotic factors, and volatiles that come from grain can be indicative of the current grain "status" quality (Christensen and Kaufman, 1969;Sinha et al, 1988;Sinha, 1990). Several studies demonstrate that grain volatiles may have important effects on host selection behavior in granivores and that these effects may differ substantially among species sharing the same resources (Levinson and Levinson, 1978;Walgenbach et al, 1983Walgenbach et al, , 1987Walgenbach and Burkholder, 1986;Trematerra and Girgenti, 1989;Phillips et al, 1993).…”

Laboratory kernel-kernel interaction experiments were carried out to assess the influence of mechanically damaged, insect-damaged, and intact maize kernels (conditioned or not) on the behavior of adult maize weevil, Sitophilus zeamais Motschulsky. S. zeamais adults were much more attracted to insect-damaged or conditioned insect-damaged kernels, than by the other two conditioned kernel categories considered. The intact kernels were more attractive than conditioned mechanically damaged kernels, but without significant difference. The "attractiveness" order of the kernel for S. zeamais adults was: insect damagedϾintactϾmechanically damaged. When fresh mechanically damaged and stored mechanically damaged kernels as well as fresh insect-damaged and stored insect-damaged kernels were compared, significant differences in the attraction of S. zeamais adults were noted.

“…Successful application of these systems to protect stored grain will require comprehensive understanding of storage environments and their interactions with pest populations. The concept of grain storages as complete ecosystems (Sinha, 1973(Sinha, , 1995Calderon, 1981) provides a framework on which to build the required understanding, and computer modeling provides the necessary tools.…”

Abstract-Protecting stored grain from insect damage, with minimum pesticide risk, will require pest management based on comprehensive understanding of storage environments and their interactions with pest populations. Computer modeling offers the means to this understanding. To obtain data sets for modeling selected pests of stored maize, we studied maize storages on six farms in a four-county area of southwestern South Carolina. Grain moisture content was measured monthly, and grain temperatures were recorded hourly for one storage season. Insect populations were monitored by taking grain and pitfall trap samples at weekly or monthly intervals. Hourly mean grain temperatures remained below optimal levels for growth and development of insects during most of the storage period. Grain moisture content varied from 11.2 to 16.4%. Forty three species of insects and one species complex, representing 26 families in four orders, were detected. The estimated importance of each species in the farm storage habitat, as measured by relative abundance and frequency of occurrence, depended on whether grain sampling or trapping was used. With trapping, Cryptolestes species (mostly C. pusillus (Schonherr», the Carpophilus dimidiatus complex (C. dimidiatus (F.), c.freemani Dobson and C. mutilatus Erichson), Sitophilus species (mostly S. zeamais Motschulsky), Xylocoris jlavipes (Reuter) and Oryzaephilus surinamensis (L.) appeared most important. With grain sampling, S. zeamais, Sitotroga cerealella (Olivier) and C. pusillus appeared most important. Insects were most abundant (or active) in the fall and again in the spring, if storage extended that long. Grain samples indicated more insects near the grain surface, but traps sometimes detected more near the bottom of the bulk. © 1997 Elsevier Science Ltd
