“…Based on these readings, moisture levels were classified into two categories: low moisture (0 ~ 15% RH) and high moisture (15 ~ 30%RH). This classification approach is based on previous experience and is consistent with the fecal moisture classification standards found in the literature [42,43].…”

Background Reintroduction represents an effective strategy for the conservation of endangered wildlife, yet it might inadvertently impact the native ecosystems. This investigation assesses the impact of reintroducing endangered Przewalski's horses into the desert grassland ecosystem of the Kalamaili Nature Reserve (KNR), particularly its effect on the spatial distribution of ticks. In a 25 km2 core area of Przewalski's horse distribution, we set up 441 tick sampling sites across diverse habitats, including water sources, donkey trails, and grasslands, recording horse feces and characteristics to analyze the occurrence rate of ticks. Additionally, we gathered the data of 669 fresh feces of horses. To evaluate the spatial dynamics between these feces and ticks, we used methods such as Fixed Kernel Estimation (FKE), Moran’s I spatial autocorrelation index, and Generalized Linear Models (GLM). Results The dominant species of ticks collected in the core area were adult Hyalomma asiaticum (91.36%). Their occurrence rate was higher near donkey trails (65.99%) and water sources (55.81%), particularly in areas with the fresh feces of Przewalski's horses. The ticks’ three risk areas, as defined by FKE, showed significant overlap and positive correlation with the distribution of Przewalski's horses, with respective overlap rates being 90.25% in high risk, 33.79% in medium risk, and 23.09% in low risk areas. Moran's I analysis revealed a clustering trend of the fresh feces of Przewalski's horses in these areas. The GLM confirmed a positive correlation between the distribution of H. asiaticum and the presence of horse fresh feces, alongside a negative correlation with the proximity to water sources and donkey trails. Conclusions This study reveals the strong spatial correlation between Przewalski's horses and H. asiaticum in desert grasslands, underlining the need to consider interspecific interactions in wildlife reintroductions. The findings are crucial for shaping effective strategies of wildlife conservation and maintaining ecological balance.

“…The olfactometric investigation on the response of the mentioned insects was carried out using a glass Y-tube olfactometer for pea leaf weevil beetles and Colorado potato beetles, while a 4-arm olfactometer arena, employed with multiple-choice tests, was utilized for winged females of the black bean aphid. Entomological studies using an olfactometer were conducted according to the methodology described in the works of Islam et al (2017) and Zhang et al (2022). The utility of such olfactometers for assessing insects' olfactory preferences has been established in various studies (Ninkovic et al 2013;Marler and Marler 2018;Masui et al 2020;Mensah-Bonsu et al 2020).…”

“…The olfactory stimulus plays a pivotal role in guiding herbivores to locate a host plant. Disrupting the reception of this stimulus, such as through the presence of other plants in proximity to the host plant, may serve as a natural method for protecting crops against plant pests (Belda and Riudavets 2010;Chen et al 2012;Finlay-Doney and Walter 2012;Al-Joary et al 2021;Zhang et al 2022). Analyzing the response of insects to plants growing in the vicinity of the host plant enables inferences about potential plant selection to achieve the desired effect in mixed crops or when organizing the surroundings of the crop (Xie et al 2012;Maharjan and Jung 2016;Islam et al 2017).…”

The study examined the impact of aqueous extracts from Urtica dioica L. and fresh nettle parts on the feeding behavior of Sitona linea¬tus L., the survival of Aphis fabae Scop. on broad bean leaves, and the feeding of L4 larvae of Leptinotarsa decemlineata Say. Olfactory responses of the insects to nettle were also investigated. Results revealed that 10, 20 and 30% concentrations of aqueous extracts from fresh nettle significantly inhibited feeding in S. lineatus females. Conversely, the 10% extract from dried nettle had the most pronounced effect on S. lineatus males. Higher concentrations of common nettle extracts increased mortality in A. fabae females and larvae, with fresh extracts exhibiting a more potent impact. The body weight of L. decemlineata larvae slightly increased with all extracts, particularly the 30% concentration of fresh nettle. While all extracts reduced food consumption by L. decemlineata larvae, no discernible differences were observed based on concentration or preparation method. Olfactometer research indicated a repellent response of L. decemlineata females to common nettle odors, but no significant influence on the behavior of S. lineatus and winged A. fabae females was observed.

To reveal population divergence in the mate choice and its mechanistic basis, the mating rhythm, mating preference and male volatile profiles of Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae) were studied. During ten days after emergence, six geographical populations of T. castaneum exhibited an identical daily or circadian mating rhythm. Males showed significant attraction to females while females did not show attraction to males. Furthermore, male attraction to females varied significantly within six populations, while female preference to males did not. Males from the HBWH population were most attractive to females sequentially followed by males from the populations of SHJD, HNZZ, GA1, GDST, and ZJJX, which was positively correlated with their 4,8-dimethyldecanal (DMD) production. Gnotobiotic reinoculation of two gut bacteria, Citrobacter freundii and Escherichia coli, to axenic males significantly enhanced their attraction to females and DMD production. It could be concluded that: (i) in the mate choice of T. castaneum, males were more like the sexual pheromone senders and females were the pheromone receivers; (ii) there was detectable divergence in the chemical communication among six populations of T. castaneum, which could be mainly attributed to alterations in the male pheromone production rather than changes in the female pheromone perception; and (iii) gut bacteria could modulate the chemical communication of the host by interfering with the pheromone production. Such knowledge will provide insights into optimizing trapping technologies for pest management.
