“…The limited studies on T. ludeni biological control so far have mainly focused on the predators from the genus Neoseiulus (Acari: Phytotseiidae). [57][58][59] However, Escudero and Ferragut, 60 and Zhang 61 showed that P. persimilis performs similarly well on both T. ludeni and T. urticae, suggesting that this predatory mite can also control T. ludeni effectively.…”

“…Yet, biological control of T. ludeni using predatory mites is still poorly understood and knowledge about the effect of predator‐ and killed prey‐induced stress on its fitness is lacking.

BACKGROUND The success of biological control using predators is normally assumed to be achieved through direct predation. Yet it is largely unknown how the predator‐ and killed prey‐induced stress to prey may contribute to biological control effectiveness. Here, we investigate variations in life‐history traits and offspring fitness of the spider mite Tetranychus ludeni in response to cues from the predatory mite Phytoseiulus persimilis and killed T. ludeni, providing knowledge for evaluation of the nonconsumptive contribution to the biological control of T. ludeni and for future development of novel spider mite control measures using these cues. RESULTS Cues from predators and killed prey shortened longevity by 23–25% and oviposition period by 35–40%, and reduced fecundity by 31–37% in T. ludeni females. These cues significantly reduced the intrinsic rate of increase (rm) and net population growth rate (R0), and extended time to double the population size (Dt). Predator cues significantly delayed lifetime production of daughters. Mothers exposed to predator cues laid significantly smaller eggs and their offspring developed significantly more slowly but these eggs had significantly higher hatch rate. CONCLUSION Predator‐ and killed prey‐induced fears significantly lower the fitness of T. ludeni, suggesting that these nonconsumptive effects can contribute to the effectiveness of biological control to a great extent. Our study provides critical information for evaluation of biological control effectiveness using predators and paves the way for identification of chemical odors from the predator and killed prey, and development of new materials and methods for the control of spider mite pests. © 2022 The Authors.

“…One of the great advantages of the use of genetically modified organisms -GMOs is the reduction in the use of insecticides, which allows the use of this tactic with biological control. Populations of phytophagous mites that develop in Bt cotton could be controlled and kept below the level of economic damage by their natural enemies, such as the predator mite Phytoseiulus macropilis Banks, 1904 (Acari: Phytoseiidae) already associated with T. ludeni (Reichert et al, 2017;Castro et al, 2014), and the cotton crop (Esteves-Filho et al, 2010) in the literature.…”

Genetically modified plants are one of the tactics used in integrated pest management - IPM. There is great concern about the impact of these plants on non-target organisms. On the other hand, there is little information in the literature on the effects of transgenics (Bacillus thuringiensis) Bt on populations of phytophagous mites, and the physiological responses that this attack promotes on plants. The objective of this work was to evaluate the biology of the T. ludeni mite in Bt cotton, expressing the Cry1F and Cry1Ac proteins. To evaluate the behavior of food and oviposition preference of the T. ludeni with Bt cotton and isohybrid. Verify if the physiological stress caused by T. ludeni’s attack is differentiated in Bt cotton. The mites were reared in Bt cotton and isohybrid, in a total of 40 replicates in the completely randomized design and the biological cycle was evaluated. The food preference and oviposition analysis were done with 10 replicates, with choice. The physiological stress was evaluated through chlorophyll fluorescence, under greenhouse conditions. The data of the T. ludeni biology were analyzed by Student's t-test, for food and oviposition preference the chi-square test was performed. Regression models were fitted for the fluorescence parameters. The model identity test was used to evaluate the differences between Bt and isohybrid treatments. Cry1F and Cry1Ac proteins have not affected the biology of T. ludeni. The photosynthetic parameters in Bt cotton plants were less influenced by T. ludeni infestation.

“…The importance of plant diversity for the development and maintenance of the diversity of natural enemies in cultivated areas has also been highlighted by Harterreiten-Souza et al (2014), Venugopal et al (2014), Mitchell et al (2014aMitchell et al ( , 2014b, Cohen and Crowder (2017), and Maisonhaute et al (2017). In Brazil, there are studies indicating the possibility of using natural enemies in the fight against soybean pests (Reichert et al 2014(Reichert et al , 2016Paz-Neto et al 2015;Cividanes et al 2017). The history of pest control shows that the evolution of resistance to the control agents that are developed is only a matter of time.…”

A Bt soybean has been recently developed, thus, efficiently regulating the populations of major lepidopteran pests. However, in other cases, these benefits have been reduced or lost because of the rapid evolution of pest resistance to the Bt toxins in transgenic crops. When pest populations are exposed to Bt crops and to refuges (non-Bt plants), the evolution of resistance is governed by the fitness of resistant individuals relative to susceptible individuals for both the presence and absence of Bt toxins. One major ecological concern regarding the biosafety of Bt crops on the environment is their potential effects on non-target organisms, especially predators and parasitoids that play an important role in pest control. This information is important for supporting insect resistance management (IRM) programs and for improving agricultural practices in a crop production system with Bt plants. Before the use of Bt plants for insect pest control in Brazil is adopted, IRM programs should be established to ensure the sustainability of this technology for integrated pest management (IPM). This review presents data on Bt soybean and lepidopteran pests as well as on the importance of natural enemies as a form of biological control, and applications for IPM and IRM.
