“…Previous studies have found that adding pollen to food has a positive effect on the growth, development and reproduction of F. occidentalis (Hulshof et al, 2003; Zhi et al, 2005). Li et al (2023) also found that rose stamens containing pollen and nectar could prolong the lifespan and enhance the fecundity of F. occidentalis more than rose petals only. Tetranychus urticae (Acarina: Tetranychidae) is an important agricultural pest that often occurs together with F. occidentalis .…”

Frankliniella occidentalis (Pergande) is a typical omnivorous insect that feeds on host plants, pollens and mite eggs, and poses a threat to crops worldwide. The insulin signalling pathway (ISP) is a typical nutrient‐sensitive pathway that participates in the regulation of various functions in insects. Serine/threonine kinases (AKTs) and phosphoinositide‐dependent kinases (PDKs) are key components of the ISP. In this study, the FoAKT and FoPDK genes in F. occidentalis were cloned, and the effects of three foods on their expression were determined. The expression of FoAKT and FoPDK in the thrips fed on kidney bean leaves supplemented with pine pollen or mite eggs was higher than in those primarily fed on leaves alone. Meanwhile, the fecundity of thrips fed on leaves supplemented with pine pollen was highest. In addition, RNA interference‐mediated knockdown of FoAKT and FoPDK decreased vitellogenin (Vg) content and Vg expression in females, shortened ovariole length, delayed egg development and reduced fecundity and offspring hatching rates. Furthermore, the synthesis of juvenile hormone (JH) was reduced, and the contents of glucose, trehalose, glycogen and trehalase were affected. These results suggest that FoAKT and FoPDK regulate the reproduction of F. occidentalis by regulating Vg and JH production as well as carbohydrate metabolism.

“…The Phytoseiidae family, commonly employed as biological control agents, comprises numerous omnivorous species that rely on both prey and floral resources, such as pollen and nectar, for their survival [ 21 , 22 ]. The oviposition of female adult mites has been found to be enhanced, likely due to the provision of pollen as a source of proteins and amino acids, thereby augmenting the fecundity of the predatory mites [ 23 , 24 , 25 ].…”

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.

The microbial composition of insect guts is typically influenced by the type of food consumed, and conversely, these microbes influence the food habits of insects. Western flower thrips (WFT; Frankliniella occidentalis) is an invasive pest with a wide range of hosts, including vegetables and horticultural crops. To elucidate variations in gut bacteria among WFT feeding on rose (Rosa rugosa) flowers (FF), kidney bean (Phaseolus vulgaris) pods (PF), and kidney bean leaves (LF), we collected adult guts and extracted DNA for 16S ribosomal RNA gene sequencing of microbial communities. The results revealed that the FF population had the highest number of annotations. Alpha diversity analysis revealed that the Chao and Ace indexes were the greatest in the PF population, indicating a higher abundance of gut bacteria. Moreover, the Simpson index was the highest in the FF population, indicating that gut bacterial diversity was the highest in the FF population. Comparison of species composition demonstrated that Proteobacteria dominated all 3 populations at the phylum level, with Actinobacteria being the subdominant phylum. At the genus level, Stenotrophomonas was the dominant bacteria in the PF and LF populations, whereas Rosenbergiella was dominant in the FF population. KEGG pathway annotation predicted that the gut bacteria of adult WFT were mainly involved in carbohydrate and amino acid metabolism. Our results revealed that the diversity and composition of WFT gut microbiota are influenced by diet, offering evidence for future studies on the ecological adaptability of WFT and the mechanisms underlying the interaction between gut microbiota and host.
