Abstract

Conducted in the conditions of green spaces in populated areas of Belarus, the studies of the nature of the sedentary insects’ (dusty-spotted caragana aphid (Therioaphis tenera Aizenberg, 1956; Rhynchota: Sternorrhyncha: Calaphididae) distribution and damage by endobiontic phytophagous insects (gall midge Dasineura sibirica (Marikovskij, 1962); Diptera: Cecidomyiidae), leaf-mining flies ((Diptera: Agromyzidae) Aulagromyza caraganae Rohdendorf-Holmanová (1959) and Amauromyza obscura (RohdendorfHolmanová, 1959)), on the leaflets of Siberian pea tree (Caragana arborescens Lam.; Fabales: Fabaceae) compound leaves) using the nonparametric Mann – Whitney and Kolmogorov – Smirnov tests did not reveal statistically significant differences in the population of left-sided and right-sided (relative to the rachis) leaflets. The mines of the larvae of the Agromyzid fly A. caraganae are located mainly on the underside of leaf blades; the use of the nonparametric Wilcoxon paired difference test confirmed this with a high level of significance (p = 0.00001). The larval mines of the Agromyzid fly A. obscura were characterized by an exclusively upper-sided location. At the same time, the population of the miner was 9.32% for the leaflets to the left of the rachis and 7.45% to the right, but the use of the nonparametric Mann – Whitney and Kolmogorov – Smirnov tests did not confirm the statistical significance (p > 0.05) of the observed differences. The use of the nonparametric Spearman rank correlation coefficients (rs) and Kendall concordance (τ) revealed a statistically significant (p < 0.01) weak negative correlation between the population of dusty-spotted caragana aphids and the order of the leaflets on the rachis. For the gall midge D. sibirica, a specific pattern of gall localization on the compound leaves of Caragana arborescens could not be revealed during the performed study. In general, the levels of damage to Caragana arborescens by sedentary sap-sucking insects and endobiontic phytophagous insects in the conditions of green spaces are assessed as insignificant, however, the nature of the damage can cause substantial loss of ornamental value of the plants.
