“…Interactions such as competition, intraguild predation (IGP), extraguild predation, and cannibalism would affect the plant-prey-predator relations in the IPM procedure, thus using multiple predatory species different in their dietary preferences and predatory behaviour is better than using single ones (Schausberger and Walzer, 2001; Momen, 2010; Momen and El-Borolossy, 2010; Momen et al ., 2013; Guo et al ., 2016; Knapp et al ., 2018; Döker et al ., 2021; Momen and Abdel-Khalek, 2009 a, b, 2021).…”

The study was aimed to conduct the population dynamics and diversity indices for three major pest species in order to design an IPM protocol in two experimental sites (Om Saber, Beheira Governorate 30°29′50.6″N, 30°46′18.8″E), and (Kom Oshim, Fayoum Governorate 29°34′40.9″N, 30°55′38.3″E). The resulted data showed statistically significant fluctuation, population dynamics, abundance, distribution, and diversity indices of the two-spotted spider mite (TSSM) Tetranychus urticae Koch (Acari: Tetranychidae), the silver leaf whitefly Bemisia tabaci Genn. (Hemiptera: Aleyrodidae), and the onion thrips Thrips tabaci Lindman (Thysanoptera: Thripidae) which recorded on four plant species belonging to Brassicaceae (Siberian (Russian) kale Brassica napus var. pabularia L. and Italian (Tuscan) kale Brassica oleracea var. palmifolia), and Lamiaceae (Spearmint Mentha spicata L. and Saudi Mint Mentha longifolia L.). The proposed IPM program consisted of predatory mites; Phytoseiulus persimilis Athias-Henriot, Amblyseius swirskii Athias-Henriot, and Cydnoseius negevi (Swirski & Amitai) (Acari: Phytoseiidae), a green pesticide, and an entomopathogenic compound. It was concluded that abiotic and biotic factors together help in explaining why various pest species build their communities rapidly and increase their parameters that become above the EIL. Such factors are hypothesized to affect the plant-arthropod, predator-herbivore, predator-predator, and tri-trophic interactions. And it recommends the application of such protocol should consider the timing of tacking an action and merging tactics together to get the maximum efficiency.

“…Papaya production is at risk, given that the reduction in cultivated areas is a result of phytosanitary problems [2] since the crop is susceptible to pest and disease attacks [4][5][6][7][8]. The main pests include the white mite (Polyphagotarsonemus latus), the spider mite (Tetranychus urticae), among other tetranychid mites, aphids Aphis gossypii and Myzus persicae, and mealybugs, such as Aonidiella comperei and Coccus hesperidum.…”

Impact of Operational Parameters on Droplet Distribution Using an Unmanned Aerial Vehicle in a Papaya Orchard

Papaya production and export is increasingly expanding in the world market due to the nutritional importance of the fruit. Phytosanitary issues, labor shortages, and unevenness in land-based costal and motorized applications compromise crops, the environment, and humankind. The purpose of this study was to evaluate the efficiency of droplet distribution using an unmanned aerial vehicle, with different application rates (12.0, 15.0, and 18.0 L ha−1) and spray nozzles (XR110015 and MGA015) in the upper (UL), middle (ML), and lower (LL) layers, and on papaya fruit clusters (BF). Water-sensitive paper labels and artificial targets were used to assess the efficiency. Coverage, density, droplet distribution, and droplet diameter were influenced by the application rates in the following order: 18.0 > 15.0 > 12.0 L ha−1, showing concentrated droplet distribution in the respective layers: UL > ML > LL > BF. The 18.0 L ha−1 rate increased the variables examined, and the droplet coverage on the UL using the XR110015 nozzle was 6.56 times greater than that found on the LL and BF. The MGA015 nozzle presented better results in the LL and BF in all variables analyzed. The UAVs were efficient in applying to the papaya crop and further studies should be carried out in order to confirm the efficacy of plant protection products applied using this technology.

“…Both behaviours are considered mechanisms to obtain vital nutrients, decrease resource competition, and avoid potential predation (Polis et al 1989; Schausberger 2003). Cannibalism and intraguild predation not only affect individual predators but also contribute to trophic complexity and biocontrol efficacy (Döker et al 2021; Pochubay & Grieshop 2012; Schausberger & Croft 2000a; Walzer & Schausberger 2013). Many members of the family Phytoseiidae (Acari: Mesostigmata) are important biocontrol agents used to control agricultural pests, including whiteflies, thrips, and spider mites (McMurtry et al 2015).…”

Larval feeding types shape the predation aggression of predatory mites in both intraspecific and interspecific encounters

Cannibalism (intraspecific predation) and intraguild (interspecific) predation are widely observed phenomena in the animal kingdom, including amongst predatory mites of the Phytoseiidae family. While the larval stage of phytoseiids is a vulnerable and important life stage, it has received less attention than the adult stage. The larvae of phytoseiid species can be categorised into three types based on their feeding behaviour: non-feeding, facultative feeding, and obligatory feeding. This study aimed to investigate the occurrence of cannibalism and intraguild predation among the larval stages of three generalist predatory phytoseiids: Amblydromalus limonicus (Garman & McGregor), Amblyseius herbicolus (Chant), and Neoseiulus cucumeris (Oudemans). We hypothesised that the larval feeding type could influence the aggressiveness of the predators in intraspecific and interspecific encounters, with obligatory-feeding larvae being the most aggressive and non-feeding larvae being the least aggressive. To test this hypothesis, we conducted a no-choice experiment under laboratory conditions using larvae to observe the prevalence of predation among conspecifics and heterospecifics in these three predatory mite species. In addition to observing predation outcomes, we measured larval body size, cheliceral size, and cheliceral morphology to investigate these parameters’ correlation with predation success. Our study revealed significant differences in the prevalence of cannibalism and intraguild predation among the three predatory species in agreement with our hypothesis: N. cucumeris larvae did not engage in predatory behaviours, while A. herbicolus displayed the highest predation success. Our findings suggest that cheliceral morphology may be a better indicator than body size of the aggressiveness of larval predation against conspecifics and heterospecifics. Our results provide valuable insights into the importance of larval behaviour in population dynamics and the development of effective pest management strategies. The study also highlights the need for further research on the larval stage of phytoseiids and emphasises the significance of considering larval behaviour when studying and managing these important predatory mites.
