“…Calliptamus italicus is widely distributed on the desert and semidesert steppes of Central Asia and peripheral regions (Huang and Cheng 1999). In recent years, serious outbreaks of C. italicus have occurred in western Russia (Azhbenov et al 2015) and southeastern Kazakhstan, and the border regions adjacent to Xinjiang of China have seen frequent migrations of C. italicus (Baybussenov et al 2014, 2015). In this study, the collection sites of C. italicus have covered the Sino-Kazakh border areas; however, in-depth studies are still needed.…”

Calliptamus italicus L. is an important pest on the desert and semidesert steppes along the Sino-Kazakh border. To elucidate the molecular mechanism of its continuous outbreaks, we studied 11 different geographic populations of C. italicus to determine: 1) the complete sequences of the entire mitochondrial cytochrome oxidase subunit I (COI) and mitochondrial cytochrome oxidase subunit II (COII) genes, and 2) performed genetic diversity, differentiation, gene flow, and molecular variation analyses. Of the 11 populations, the Yining County (YNX) population had the highest haplotype diversity and Pi values. There are significant differences in Tajima’s D and Fu’s Fs (P < 0.05). The fixation index Fst values of the total C. italicus population were 0.03352, and its gene flow Nm values of the total C. italicus population were 15.32. Taken together, there were five main findings: 1) the current genetic differentiation of C. italicus arose within populations; 2) genetic exchange levels were high between geographical populations; 3) genetic variation level was low; 4) C. italicus populations likely expanded in recently, and 5) there was no significant correlation between genetic distance and geographic distance for any geographic population. Findings from this study indicate that frequent gene exchange between populations may enhance the adaptability of C. italicus along the Sino-Kazakh border, leading to frequent outbreaks.

“…Since the natural and climatic data of North Kazakhstan are considered the most optimal environment for the spread and harmfulness of all locust species [Kambulin, 2018], including nongregarious species [Baibussenov et al, 2015], four regions of North Kazakhstan were selected and covered as the research area, namely, the Akmola, Pavlodar, Kostanay, and North Kazakhstan regions. The analyses were carried out for the period 1999-2021.…”

“…They damage grains, legumes, forage crops, and pasture lands [Kambulin, 2018]. According to the conducted observations [Baibussenov et al, 2015], in recent years there has been an increase in the number of these phytophages and pest infestation exceeding the economic harmfulness threshold (above 10 individuals per 1 sq. m) has been observed in many grain crops of North Kazakhstan.…”

The paper considers the approaches and possibilities of using two types of simulation: the species distribution model and the ecological niche model. The study aimed to simulate favorable habitats and the potential spread of non-gregarious locust pests in North Kazakhstan based on satellite and ground data for preventive measures. The MaxEnt software was used to conduct the simulation. According to the species distribution model, high indicators of the habitat are predicted in the Pavlodar and Kostanay regions, on 69.9-100% of the studied territory. With the simulation of ecological niches for non-gregarious locust pests, the following class boundaries were determined for the transition from quantitative to qualitative indicators from I (85-100%) to IV (0-50%), which indicates the zones of the probability of pest attack from a higher indicator to a lower one. According to the fundamental model, high indicators of the area of pest occurrence, that is, zones I and II, are located in the central and northern parts of the Pavlodar region. Here, the probability of non-gregarious locust occurrence of zone I and II with a ratio of 1:1 is observed in a slightly arid, moderately warm agro-climatic zone. In the southern part of the Kostanay region, the simulation predicts the probability of occurrence on zones I and II with a ratio of 1:2 in the moderately arid warm agro-climatic zone of this region. In the southern and southeastern parts of the Akmola region, the model predicts the probability of occurrence in zones I and II with a ratio of 1:3 in a slightly humid, moderately warm agro-climatic zone of the region. The considered species distribution model can be used as a modern tool for long-term forecasting of the spread of non-gregarious locust pests since it takes into account the peculiarities of the agricultural landscape. The fundamental niche model can be used in a long-term population forecast since it focuses more on the theoretical conditions of pest habitats.

“…One of the factors contradicting the conservation of biodiversity and ensuring phytosanitary safety is massive pesticide treatments used against locust pests as the only method of crop protection in cases of exacerbation of the phytosanitary situation (Baibussenov et al, 2014). Despite the annually carried out massive treatments against locusts, nowhere is the phytosanitary situation as critical as in arid and subarid zones, which occupy most of the territory of Kazakhstan (Kurishbaev and Azhbenov, 2013;Baybussenov et al, 2015;Azhbenov et al, 2015).…”

The article presents the results of many years of research on the phytosanitary state of agricultural land for non-gregarious locust pests. As polyphagous pests, non-gregarious locusts are one of the key destabilizing factors in the production of economically important agricultural plants in the agricultural regions of Northern Kazakhstan. Research on the long-term population dynamics of non-gregarious locust pests to determine bioecological regularities and factors influencing them for early forecasting an increase in the number and rational planning of plant protection products is very relevant. The studies were carried out in 1999-2019 based on the use of data on the distribution of non-gregarious locusts in Akmola, Pavlodar, Kostanay and North Kazakhstan regions. Numerical indicators of pest colonization and abundance indices were used as diagnostic predictors characterizing the phase state of species in a given year, which made it possible to establish patterns of population dynamics of locusts. Based on the research results, the authors concluded that the expected onset of certain phases of the dynamics of the phytophagous population was not always preserved and was subject to change under the influence of environmental factors. The trend in the dynamics of the number of studied phytophages depends to a large extent on the weather conditions of the previous and current year, as well as on the full amount of volumes and compliance with the necessary procedures. The data obtained can be proposed as criteria for predicting the phase state of populations of non-gregarious locusts in Northern Kazakhstan to justify and plan protective measures, as well as to improve phytosanitary control over non-gregarious locusts.
