“…The predatory mite Neoseiulus bicaudus (Acari: Phytoseiidae) has a wide distribution across several countries, encompassing Russia, Greece, Iran, Spain, Italy, Tajikistan, Cyprus, and the United States [ 29 , 30 , 31 ]. It is a facultative predator with generalist feeding habits, capable of regulating the populations of various pest species including spider mites, whiteflies, and thrips [ 32 , 33 ]. N. bicaudus has demonstrated effective control against low densities of Tetranychus turkestani on bean and cotton crops [ 34 , 35 ].…”

Neoseiulus bicaudus is a predatory mite species that could potentially be used for the biological control of spider mites and thrips. Floral resources can provide excellent habitats and abundant nutrients for natural enemies. The objective of this experiment was to evaluate the effects of eight floral resources on the longevity, fecundity, and predation ability of N. bicaudus. Among the considered plants, Cnidium monnieri led to the highest longevity (24 days) and fecundity (13.8 eggs) of N. bicaudus, while Tagetes erecta resulted in the lowest longevity (7 days) and fecundity (0.1 eggs) observed in the predatory mites. By comparing the effects of three nectar and pollen plants on the predation of predatory mites, it was observed that N. bicaudus still exhibited a type II functional response to Tetranychus turkestani. In the presence of pollen, the predation efficacy (a/Th) of N. bicaudus exhibited a lower value, compared to that in the absence of pollen (Control: a/Th = 24.00). When pollen was supplied, the maximum consumption (1/Th) of predatory mites was higher than in its absence (Control: 1/Th = 9.90 d−1), with the highest value obtained in the presence of B. officinalis pollen (B. officinalis: 1/Th = 17.86 d−1). The influence coefficient of predation of N. bicaudus on T. turkestani in the presence of pollen was compared in the presence of three nectar and pollen plants: Cnidium monnieri, Centaurea cyanus, and Borago officinalis. At low prey densities, the influence coefficient of C. cyanus exceeded that of B. officinalis, and the overall influence coefficient values were negative (i.e., the presence of pollen reduced predatory mite feeding on T. turkestani). They exhibited similar values at high prey densities, and all of the influence coefficient values were close to 0 (i.e., the presence of pollen had no effect on predatory mite feeding on T. turkestani). The findings revealed that diverse plant species exert differential impacts on N. bicaudus, with some influencing its lifespan and others affecting its reproductive capabilities. Furthermore, the presence of nectar and pollen plants had a significant impact on predatory mite feeding on T. turkestani at low prey densities; however, this effect diminished as the prey density increased. Therefore, we recommend planting C. monnieri, C. cyanus, and B. officinalis in the field to ensure an ample population of predatory mites. The obtained results hold significant implications for the utilization of nectar and pollen plants in eco-friendly pest management strategies within agricultural contexts.

“…Since C. eruditus was identified as a predator of acarid mites, it has been commercially mass-produced and employed as a biological control agent in practice [27][28][29]. Extensive research has documented its efficiency not only as a predator of storage mites from the family Acaridae and Glycyphagidae [27,[30][31][32][33] but also as a promising candidate for controlling the poultry red mite Dermanyssus gallinae (De Geer) [28,34]. To fully understand its potential as a biological control agent, an in-depth understanding of the life history strategies, such as egg-guarding behavior, is urgently needed.…”

Maternal Care Behavior and Its Consequences in Competition

Parental care behavior has evolved as a life history strategy to improve reproductive success, particularly in organisms facing challenging environments. However, the variation in maternal care, such as egg-guarding behavior in response to the social environment and the associated ecological consequence of competition, remains largely unknown. This study addresses a gap in current knowledge by examining the plasticity of maternal care behavior in the predatory mite C. eruditus and its impact on offspring survival and intra- and interspecific competition. Our results demonstrated that the reproductive females frequently exhibit egg-guarding behaviors, with enhanced maternal care efforts when the interspecific competitor is present. Egg masses are significantly more vulnerable to predation in the absence of maternal care. Guarding females increased egg survival rates and adversely influenced the survival of both con- and heterospecific competitors, with higher mortality rates being detected. Our findings highlight the ecological significance of maternal care behaviors and suggest that releasing C. eruditus and Neoseiulus cucumeris (Oudemans) together is not recommended for pest management in storage products.

Numerous arthropod pest species can cause significant losses in the quantity and quality of stored products. Currently, the most common pest control strategy is the use of a limited number of authorized synthetic insecticides. However, the overuse of these insecticides has led to an increase in pesticide resistance, reducing their effectiveness. Biological control using natural enemies offers an effective alternative to prevent insect populations from reaching pest status. Generalist predatory mites are noted for their potential as biocontrol agents as they can prey on a large variety of pest species and are easy to manage and apply. We evaluated the suitability of three predatory mites, Blattisocius tarsalis, Cheyletus malaccensis, and Amblyseius swirskii, for controlling several insect pests that are usually present in stored cereals. Prey acceptance and predation rates were assessed in experiments in which a known number of preys were offered to mite females in different arenas. Blattisocius tarsalis and C. malaccensis exhibited broad polyphagous behavior on insect pests commonly found in stored rice and other cereals. In contrast, A. swirskii was ineffective against these pest species. The efficacy of B. tarsalis and C. malaccensis, individually or in combination, in controlling populations of Oryzaephilus surinamensis and Sitotroga cerealella in medium-size arenas was also evaluated. Whether individually or in combination, both predatory mites reduced populations of O. surinamensis or of S. cerealella by half. These results suggest that periodic releases of these predatory mites could maintain these pest populations under control.
