“…Coffee crops naturally harbor a great diversity of natural enemy species, such as predatory and parasitoid wasps, green lacewings, ants, ladybugs, predatory mites, and entomopathogens (Reis et al, 2002;Fernandes et al, 2008;Amaral et al, 2010;Rodrigues-Silva et al, 2017;Moreira et al, 2019;Botti et al, 2021;Rosado et al, 2021). However, their abundance in coffee monocultures is not always enough to keep pest populations below economic injury levels; for instance, predators and parasitoids, although carnivores, need to feed on plant-derived food, such as nectar and pollen, to supplement or complement their diet or during a non-carnivorous life stage (Olson et al, 2005;Venzon et al, 2006Venzon et al, , 2019. In coffee monocultures, these resources are not available throughout the year, as coffee blooms for a limited period and the flowers last only a few days, when they are already visited by pollinators (Peters and Carroll, 2012).…”

“…Non-crop plants (i.e., spontaneous plants) can also be managed for conservation biological control purposes in agroecosystems, as they provide resources and conditions that allow natural enemy survival, growth, and reproduction, even when their prey are scarce or absent (Venzon et al, 2019). One of the main advantages of using non-crop plants to habitat manipulation is that they grow rapidly and spontaneously, and generally farmers know them well.…”

Coffee plants host several herbivorous species, but only few are considered pests. Brazil is the largest coffee producer of the world, and the two key coffee pests of the crop in the country are the coffee leaf miner Leucoptera coffeella and the coffee berry borer Hypothenemus hampei. However, in some regions or on specific conditions, species of mites and scales can also cause damage to coffee plants. Conventional management of coffee pests relies on chemical pesticides, and it is the most commonly used strategy in Brazil, but environmental problems, pest resistance, and toxicity-related issues have led coffee growers to search for alternatives for pest control. Agro-ecological strategies suitable to coffee cultivation can be adopted by farmers, based on plant diversification, in order to provide resources for natural enemies, such as nectar, pollen, shelter, microclimate conditions, and oviposition sites, thereby promoting conservation biological control. Here I revise these strategies and report the results from research in Brazil. I include results on agroforestry, use of cover crops, and non-crop plant management. These are complemented by curative measures based on the use of organic farming-approved pesticides that can be employed when the agro-ecological practices are not yet consolidated. I also present the cultural control method used by several coffee producers in Brazil to decrease coffee berry borer damage.

“…The increase in plant diversity aims to provide shelter and food (such as nectar, pollen, and honeydew) to the natural enemies. The conservation of strips of wild plants within the cultivation area, for example, provides the permanence of natural enemies that use other foods besides their preys (Venzon et al, 2019). The cowpea consortium in succession to corn favored the diversity and the abundance of predatory mites in Jatropha curcas (Cañarte et al, 2020).…”

Biological control is a worldwide trend and has been prominent as an effective and compatible strategy for use in Integrated Pest Management programs. In Brazil, the control of these organisms using biological agents has been used in several agricultural systems, including floriculture. This paper approaches biological control from the perspective of the interaction between organisms in nature, applied as a pest management strategy. Knowledge about the dependence and reciprocity among populations in a natural environment is fundamental to understanding that this control method is nothing more than an exploiting of a natural ecological service. Considering that, for the biological control of a pest we must increase the population density of natural enemies, we report on the two main ways to achieve this increase: conservative biological control and augmentative biological control. The first is done by modifying the environment’s vegetation structure to favor natural enemies’ maintenance or their attraction to the crops. The second is done by mass rearing entomophagous and entomopathogen species with attributes that can ensure their function as control agents when released in crops. Among such agents, we emphasize those produced and marketed in Brazil for application in ornamental plants. Finally, we report on the technologies most recently employed to increase the appropriate use and the efficiency of these biological control agents.

“…In the same way as in the case of the host plants that display constitutive resistance due to VOC presence, the companion plants can control insect pests either directly, by disrupting host location or deterring their establishment by attracting the pest away, or indirectly, by attracting those natural enemies that control the pest population (Parker et al, 2013). For example, coriander (Coriandrum sativum L.) releases volatiles that mask the odours of the tomato, making difficult their recognition by pests (Venzon et al, 2018;Giorgini et al, 2018). Besides attracting pollinators and feeding useful fauna with pollen, companion plants can serve as trap-crops, hosting most pests or they release volatiles, that also attract predators, such as ladybeetles (Venzon et al, 2018).…”

For integrated pest management (IPM) and organic farming, breeding resistant varieties is one of the most eco-friendly approaches, that goes along botanicals and other different cultural practices, as the use of companion plants. Among the many pest species that invaded the whole world in the last decades, one of the most frightening is the tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), a devastating pest of cultivated tomato worldwide. Tomato is one of the most important agricultural commodities, including the main mean of subsistence in many countries from Africa and middle East. As chemical pesticides failed to control de pest spread and led to many reports of resistant populations, alternative methods for tomato leafminer management must be quickly developed. Many of such alternatives count on a wide range of chemical compounds. The chemical compounds most often responsible for “constitutive resistance”, synthetized by tomato are methyl-ketones (2-tridecanone), sesquiterpenes (zingiberene), and acyl sugars (acylglucose and acylsucrose) while the chemical compounds produced by other plants, used as isolated substances or mixtures, which have antifeedant, growth inhibiting, repellent, and insecticide effects, are azadirachtin, carvacrol, cinnamaldehyde, citronellal, eugenol, linalool, nicotine, pyrethrin, rotenone, thujone, thymol, α-terpineol, 1.8-cineol, etc. Many of them are already commercially available but their efficacy and use differ widely. Therefore, a deeper understanding of the resistance mechanism of solanaceous species related to chemical compounds and substances important for IPM plans developed against T. absoluta is required by the breeding programs.
