Aflatoxins (AFs) are toxic secondary metabolites produced mostly by Aspergillus species. AF contamination entering the feed and food chain has been a crucial long-term issue for veterinarians, medicals, agroindustry experts, and researchers working in this field. Although different (physical, chemical, and biological) technologies have been developed, tested, and employed to mitigate the detrimental effects of mycotoxins, including AFs, universal methods are still not available to reduce AF levels in feed and food in the last decades. Possible biological control by bacteria, yeasts, and fungi, their excretes, the role of the ruminal degradation, pre-harvest biocontrol by competitive exclusion or biofungicides, and post-harvest technologies and practices based on biological agents currently used to alleviate the toxic effects of AFs are collected in this review. Pre-harvest biocontrol technologies can give us the greatest opportunity to reduce AF production on the spot. Together with post-harvest applications of bacteria or fungal cultures, these technologies can help us strictly reduce AF contamination without synthetic chemicals.

Eriophyid Mites

Effective management of the interactions within the mite community is critical to biological control of economically damaging phytophagous mites such as Panonychus ulmi Koch (Tetranychidae) (Clements and Harmsen 1990). Although much is known about the potential role of phytoseiid mites in controlling P. ulmi (Dover et al. 1979), mites from at least seven other families may be present in apple orchards (Thistlewood 1991). Stigmaeid mites are predators which may play a beneficial role in biological control in conjunction with phytoseiids (Clements and Harmsen 1992). Eriophyid mites are phytophagous but seldom cause economic damage, and may compete with tetranychids and provide alternative food for predators of tetranychids (Croft and Hoying 1977).

Critical Damage

Whitefly complex is one of the most severe pests affecting different crops of significant agricultural interest. It causes critical damage to plants, and hence considerably affect crop productivity and the related commercials. This insect has been managed using insecticides; however, there have been reports of resistance of this insecticide to various active ingredients, making it difficult to reduce this pest’s population. Hence, other ways of handling this insect population have been investigated, including through biological control. Several past studies have reported the existence of natural enemies of the whitefly, including coccinellids such as those belonging to the genus Delphastus have gained much attention. These coccinellids are predators and hence perform the important role of controlling pest population. Moreover, the whitefly is a staple food in certain diets.

Predatory mites represent important biological control agents and those belonging to the Phytoseiidae family are the most promising for the control of phytophagous mites and small insects. The control of key pests of tomato and other solanaceous crops, highlighting phytophagous mites, has been a challenge and the biological control constitutes a promising strategy. Prospecting predatory mites in wild host plants, natural environments as well as in agroecosystems is relevant because these non-crop and crop areas can serve as reservoirs for promising species for biological control programs. This study aimed to know the Phytoseiidae fauna associated with wild and cultivated solanaceous plants in a poorly prospected area in Brazil, the Central-West Region. A detailed taxonomic identification of phytoseiid mites was conducted, and the most important morphological traits are presented for each species. In addition, associated phytophagous mites mainly belonging to the Tetranychidae, Tenuipalpidae and Eriophyoidea were identified. Surveys were carried out in 23 species of solanaceous collected in the Distrito Federal (12 areas) and Goiás State (1 area), from February 2017 to January 2018. Nineteen species of predators belonging to ten genera were recorded: Amblyseius (2 species), Euseius (3), Galendromus (1), Iphiseiodes (1), Neoseiulus (3), Paraphytoseius (1), Phytoseius (3), Proprioseiopsis (2), Typhlodromalus (2, one probably new to science) and Typhlodromips (1). Solanum lycocarpum was the solanaceous that harbored the highest richness (11 species), as well as the one with the highest abundance of phytoseiids (250 specimens). Typhlodromalus aripo was the most common species, being the most abundant (423 specimens; 32%) and registered on the largest number of hosts (14). Many of phytoseiid species found present morphological traits that facilitate their occurrence in leaves with trichomes, as in the case of tomato and other cultivated solanaceous. These traits and the association between predators and phytophagous mites may indicate that these species are promising for biological control programms. Thus, extensive studies to assess the efficiency of the identified predatory mites to control key solanaceous pests are required.
