Environmental contamination with xenobiotics affects organisms and the symbiotic relations between them. A convenient object to study relationships between parasites and their hosts is the host-parasite system " Linnaeus, 1758 (Coleoptera, Tenebrionidae) (Hammerschmidt, 1838) Stein, 1848 (Eugregarinorida, Gregarinidae)". For this experiment, we took 390 larvae and 24 organic compounds. Groups of mealworms, 15 in each, were subjected to those compounds for 10 days. Then, we recorded the vitality of both the larvae of and . To assess how had affected the hosts' wellbeing, we looked for changes in the larvae's body mass and compared them to the number of gregarines in their intestines. The vitality of the larvae was inhibited by cyclopentanol and 2-naphthol. The intensity of gregarine invasion was reduced by diphenyl ether, benzyl alcohol, catechol, and 3-aminobenzoic acid. No effect on the number of gregarines was produced by 3,4,5-trihydroxybenzoic acid, cyclohexanemethanol, phenol, benzalkonium chloride, maleic anhydride, cyclohexanol, resorcin, benzoic acid, 2-methylfuran, terpinen-4-ol, 1-phenylethylamine, dibutyl phthalate, 3-furancarboxylic acid, 5-methyl furfural, 6-aminohexanoic acid, succinic anhydride, o-xylene, and benzaldehyde. In the infected individuals, the mean number of equaled 45 specimens per host. The groups of smaller mealworms had fewer gregarines. Positive correlation was seen between growth rates of larvae and the intensity of invasion by gregarines.
外源性生物对环境的污染会影响生物体及其之间的共生关系。研究寄生虫与其宿主之间关系的一个便利对象是宿主 - 寄生虫系统“Linnaeus, 1758（鞘翅目，拟步甲科）（Hammerschmidt, 1838）Stein, 1848（真簇虫目，簇虫科）”。在本实验中，我们选取了390只幼虫和24种有机化合物。将每组15只黄粉虫暴露于这些化合物中10天。然后，我们记录了 幼虫和 的活力。为了评估 如何影响宿主的健康状况，我们观察了幼虫体重的变化，并将其与肠道中簇虫的数量进行比较。环戊醇和2 - 萘酚抑制了幼虫的活力。二苯醚、苯甲醇、邻苯二酚和3 - 氨基苯甲酸降低了簇虫的侵染强度。3,4,5 - 三羟基苯甲酸、环己烷甲醇、苯酚、苯扎氯铵、马来酸酐、环己醇、间苯二酚、苯甲酸、2 - 甲基呋喃、萜品醇 - 4、1 - 苯乙胺、邻苯二甲酸二丁酯、3 - 呋喃羧酸、5 - 甲基糠醛、6 - 氨基己酸、琥珀酸酐、邻二甲苯和苯甲醛对簇虫数量没有影响。在受感染的 个体中，每个宿主的平均 数量为45个标本。较小的黄粉虫组中的簇虫较少。观察到 幼虫的生长速率与簇虫的侵染强度之间存在正相关。
