Summary: In this study, it was found that different citrus species emit varying levels of biogenic volatile organic compounds (BVOCs) that result in different attractive behaviors towards the citrus woolly whitefly, A. floccosus. Specifically, the compound D-limonene from lime showed the strongest attractive behavior in olfactometry experiments.

Summary: Detection and identification of invasive species like whiteflies are crucial for preventing their introduction and establishment. This study focuses on the characteristics of the puparium and adults of the woolly whitefly, Aleurothrixus floccosus, a recent invasive species in India. The findings provide valuable information for quarantine measures and highlight the genetic relatedness of A. floccosus to other whitefly species.

Summary: This study compared the virulence of four entomopathogenic fungi strains against different life stages of B. tabaci and found that L. attenuatum and B. bassiana were more effective against B. tabaci. Additionally, fourth-instar nymphs, eggs, and adult stages of B. tabaci were less resistant to the fungi compared to earlier instar nymphs.

Summary: The study demonstrated that the entomopathogenic fungus Simplicillium lanosoniveum is highly effective in controlling all developmental stages of the rugose spiraling whitefly (RSW) on coconut trees, with significant reductions in egg and nymphal populations. This fungus has the potential to be developed as a mycoinsecticide for managing RSW infestations.

Summary: The research evaluated the potential of using the citrophilous mealybug's sex pheromone for mating disruption. The results showed that this technique has great potential for controlling the citrophilous mealybug, with the advantage of being environmentally friendly and non-toxic.

Summary: To control the invasive whitefly pest and reduce its damage to vegetable crops and ornamental plants, the release of natural enemies has become an important method of biological control. This study evaluated the impact of the mirid predator on the morphology and physiology of eggplants in the presence of whitefly infestations. The results showed that the presence of the predator mitigates the damage caused by whitefly infestations and helps to understand the multitrophic relationships between plants, pests, and natural enemies.

Summary: This study provided a detailed ethogram of GW mating behavior for the first time and characterized the vibrational signals emitted during pair formation. The analysis showed that courtship is a key stage for mating success in GW, leading to overlapped duet stage. The possibility of using vibrational playbacks to interfere with GW mating communication is considered a promising option for pest control in greenhouses.

Summary: This study investigated the differentiation of soybean leaves infested with Bemisia tabaci using hyperspectral sensing. The results showed that hyperspectral sensing could effectively discriminate different levels of infestation and help improve monitoring of whitefly populations in soybean fields.

Summary: The ingestion of plant flavonoids enhances the tolerance of Bemisia tabaci to certain insecticides by increasing the activity of cytochrome P450 enzymes, which disrupts the mechanism of the insecticides.

Summary: The study provides important information about the biology, natural enemies, and management plan of the invasive species Singhiella simplex. In the USA, the pest is mainly found in Arizona, California, and Florida, with central and south Florida being its primary distribution area. The parasitoid wasp Baeoentodon balios and the predatory beetle Delphastus pallidus are the dominant natural enemies of this pest.

Summary: The woolly apple aphid is a major pest of apple trees and the generation of its chromosome-level genome assembly provides a valuable resource for research in various areas such as insect-plant interactions and pest resistance management. The phylogenomic analysis reveals the evolutionary relationships of woolly apple aphid with other aphid species, highlighting its importance in the aphid subfamily Eriosomatinae.

Summary: Facultative endosymbionts can influence the growth, physiology, and behavior of their arthropod hosts. In the invasive whitefly Bemisia tabaci Mediterranean, the facultative endosymbiont Candidatus Cardinium hertigii alters stylet probing behavior, resulting in differences in sustained ingestion of plant phloem. These findings offer insights into the fitness costs of Cardinium-infected B. tabaci.

Summary: The study found that two tomato cultivars, Kilele F1 and Red Beauty F1, were no longer attractive to the greenhouse whitefly, Trialeurode vaporariorum, after being infested. Analysis of emitted volatiles identified several compounds, and it was determined that 1,8-cineole, p-cymene, and limonene did not attract the whitefly when combined with the most attractive tomato cultivar, Red Beauty F1.

Summary: The function of NPC1 gene was investigated in the whitefly Bemisia tabaci, a hemipteran pest. It was found that B. tabaci had only one NPC1 homolog, which was expressed throughout its developmental stages and body parts. Knockdown of BtNPC1 resulted in reduced survival, fecundity, and affected nymph development and metamorphosis. These findings suggest that BtNPC1 plays a crucial role in sterol-related biological processes of B. tabaci and could be targeted for novel pest management approaches.

Summary: The sweetpotato whitefly is a broadly invasive pest of great economic significance, containing more than 44 cryptic species, with MEAM1 and MED being the most invasive and destructive. Research in China has focused on understanding the changes in cryptic species composition and invasion characteristics, as well as factors affecting the displacement of dominant cryptic species.
