Article Abstract

Otobius megnini (spinose ear tick) is a cosmopolitan soft tick that parasitizes domestic and wild mammals, as well as humans. The larval and nymphal stages are common parasites that feed on blood inside the canal ears of hosts, while adults are nonfeeding and live off the host. Different nymphal stages of O. megnini were collected from a jaguar (Panthera onca) suffering from otitis in captive conditions from Guerrero, Mexico. This is the first documentation worldwide of O. megnini in a jaguar with otitis. The presence of this tick species represents a risk of transmission to animals and humans exposed to the nymphal stages of the tick.

The ectoparasitic honeybee (Apis mellifera) mite Tropilaelaps mercedesae represents a serious threat to Asian apiculture and a growing concern for global beekeeping due to its high reproductive capacity and host adaptability. However, the regulatory mechanisms underlying its host adaptation across life stages remain poorly characterized. Here, we performed integrated transcriptomic, proteomic, and metabolomic analyses of female mites at 4 key postembryonic developmental stages: protonymphs, deutonymphs, mature adults, and reproductive adults.

Disruption of egg and nymph development via RNAi-mediated Glutamine: fructose-6-phosphate aminotransferase knockdown in Locusta migratoria: A promising strategy for pest management.

Glutamine: fructose-6-phosphate aminotransferase (GFAT) is the first rate-limiting enzyme in the hexosamine biosynthetic pathway, which plays a crucial role in various biological processes, including chitin metabolism in insects. Locusta migratoria, a widespread and highly destructive agricultural pest, poses a significant threat due to its rapid reproduction and long-distance migration. In this study, we identified and characterized LmGFAT as a key regulator of locust development.

The brown planthopper (BPH), Nilaparvata lugens is a typical pesticide-induced resurgent rice pest. A previous study showed that a fungicide, jinggangmycin (JGM)-treated rice led to markedly increased sugar content and (Insulin-like Peptide 2) ILP2 in response to sugar-mediated TOR signaling and stimulated fecundity in BPH. However, the role of the other ILPs in response to types of carbohydrate compounds remained poorly understood.

The brown planthopper (BPH), Nilaparvata lugens (Stål), is a typical insecticide-induced resurgence rice pest that causes severe damage to rice in Asian countries. Previous studies have shown that the fungicide Jinggangmycin (JGM), used to control rice sheath blight disease, can stimulate BPH fecundity; however, the molecular mechanism remains to be further explored. In this study, based on transcriptomic analysis, we found that the PI3K-Akt signaling pathway was significantly enriched in BPH after feeding on JGM-treated rice, where the NlPR-L and NlABD4-L genes were significantly upregulated.

A resident of Monmouth County, New Jersey, United States removed an engorged nymphal tick after returning from travel to Costa Rica. The tick was identified by cox1 barcoding as Amblyomma tapirellum  Dunn, 1933, a Central American species whose immature stages are undescribed. This species is associated with wet, tropical forests, and most host records come from Baird's tapirs (Tapirus bairdii), though feeding on other mammalian orders and on humans has been observed.
