“…Os levantamentos dos artigos nas ferramentas de pesquisas trouxeram resultados que enfatizam a presença do T. urticae e como seus agentes controladores, os ácaros predadores P. persimilis e/ou N. californicus. Interações entre os indivíduos são comuns em sistemas complexos e influenciam no desempenho de todos os indivíduos onde a dinâmica de todos é afetada mutuamente (Silva, et al, 2012;Carvalho, et al, 2018).…”

Os ácaros-praga causam danos econômicos, portanto é essencial conhecer as relações entre praga e predador. Para isso, foi realizada uma revisão bibliométrica sobre o controle biológico de ácaros da família Tetranychidae em cultivos agrícolas. O estudo foi desenvolvido utilizando os descritores “controle biológico”, “ácaros predadores”, “Tetranychidae” nas plataformas de pesquisa dos periódicos Web of Science, Science Direct, Springer, Scopus e Capes, utilizando dois métodos de análise: Banco de dados através do Microsoft Excel e VOSviewer. Nas bases de dados foram encontrados 2.186 artigos e selecionados 17. O software VOSviewer agrupou 306 artigos importantes ao tema discutido por centenas de autores, com evidências para produtores de alimentos. Nos dados do Microsoft Excel, a espécie Tetranychus urticae (praga) e Neoseiulus californicus (predador) foram as mais citadas. Em relação ao período de publicação, de 2019 até 2021 houve um crescimento nas pesquisas com o uso do controle biológico utilizando ácaros predadores no controle de ácaros fitófagos de importância agrícola. A análise evidencia que o controle biológico sobre ácaros-praga vem sendo estudado pela comunidade acadêmica, demonstrando a importância deste manejo.

“…When released simultaneously they are likely to come into contact and interact. In situations in which two biological control agents that share the same resource are involved, it is paramount to explore the array of intraguild interactions that might occur between both organisms to establish their compatibility and optimal use (da Silva et al 2012). While interactions between intraguild predators have been widely documented, there is far less information concerning intraguild interactions between predators and pathogens that share the same resource (Flick et al 2016).…”

Interactions Between the Nematode Heterorhabditis amazonensis JPM4 and the Predator Macrolophus basicornis: Two Natural Enemies of Tuta absoluta Native to South America

et al. 2019

Entomopathogenic nematodes (EPNs) and predatory mirids are among the most effective natural enemies for the control of Tuta absoluta, a key pest of tomato worldwide. In the case of South America, the native EPN Heterorhabditis amazonensis and the predator Macrolophus basicornis (Stal) coexist in tomato. The intraguild interactions of two ENPs, H. amazonensis JPM4 and the widely used Steinernema carpocapsae, with the predator M. basicornis, were studied in laboratory setups with the objective of evaluating the potential interactions between them. We hypothesized that the two natural enemies do not interact negatively. The first nymphal stage of the predator was not affected when exposed to tomato leaves directly sprayed with both EPNs, which we attributed to the small size of its stylet. Individuals treated with H. amazonensis JPM4 had low mortality rates in all developmental stages with a maximum of 1.3%. Mortality was higher when the predator was exposed to S. carpocapsae (28% for adults) and correlated positively with increasing developmental stages. In prey choice tests between larvae infected with H. amazonensis and uninfected larvae, M. basicornis fed indistinctively showing no clear preference. When presented with choice larvae infected with S. carpocapsae, the consumption of healthy larvae was higher. In a no-choice prey acceptance experiment, M. basicornis preyed on both healthy and infected larvae with no difference in larvae consumed. Predators that had fed from infected larvae did not exhibit signs of nematode infection and survived. Our results indicate that the South American native H. amazonensis JPM4 and M. basicornis do not show a negative interaction and are promising candidates for combined use in T. absoluta biological control.

“…In biological control programs, more than one species of predator may be used to control a group of pests in the crop system (De Clercq et al 2003). Therefore, understanding the interactions between species of natural enemies in a food web is important to improve pest management programs and reduce possible negative effects those interactions might cause (Knaak et al 2009;Silva et al 2012). In this context, predators might interact with individuals of the same (intraspecific) and different species (interspecific) and the results of these interactions are essential to estimate the potential growth of a population in the habitat.…”

Cannibalism and intraguild predation between endemic and introduced coccidophagous lady beetles (Coleoptera: Coccinellidae)

et al. 2022

The Chilocorini lady beetles Tenuisvalvae notata (Mulsant) and Cryptolaemus montrouzieri Mulsant are important biological control agents being able to share their habitat and compete for their preferred prey, mealybugs. Whereas T. notata is native to South America, C. montrouzieri is an Australian species introduced in Brazil in a biological control program of mealybugs. This work investigated the cannibalism and intraguild predation between these species in the absence of prey. To test for intraguild predation, one individual larva (instars 1-4) from each species was confined for 24 h with another larva of the same instar or the next instar, in a total of 10 combinations. In addition, we measured predation of T. notata adults upon eggs, larvae, pre-pupae and pupa of C. montrouzieri, and vice versa. Cannibalism within the species was also tested across adults, larvae and eggs. Results showed asymmetric interactions in favour of C. montrouzieri, which acted as intraguild predator more than 80% of the time when paired with larvae of T. notata either of the same or different instar. In addition, C. montrouzieri adults preyed more upon larvae and eggs of T. notata than the contrary. There was no intraguild predation upon pre-pupae and pupae. Cannibalism was high upon eggs and first instar larvae of T. notata (89.5% and 65%) and C. montrouzieri (100% and 55%), respectively. Therefore, the exotic C. montrouzieri outcompeted the native T. notata and could become a threat to this endemic species in areas of simultaneous occurrence and under prey scarcity. Thus, the interactions between these lady beetles could affect the success of biological control of mealybugs.
