The New Zealand fauna of snout moths (Pyraloidea) predominantly consists of endemic species. During 2017 and 2018, 56 species of Pyraloidea in 1,749 individuals were collected at 14 localities. All species were screened for Wolbachia-infection, with specimens of eight species (14%) being positive, of which six species belong to Scopariinae. This is the first record of Wolbachia-infection amongst New Zealand Lepidoptera. The most common pyraloid species, Eudonia submarginalis and Orocrambus flexuosellus, were analysed for a larger set of individuals looking for sex ratio and Wolbachia-infection. There is a sex ratio bias towards females in both species, but it varies in space and time. Wolbachia is found in all populations of E. submarginalis with 10–80% of the tested individuals being positive, depending on locality. No Wolbachia-infection has been found in O. flexuosellus. Thus, sex ratio bias might be linked to Wolbachia-infection in E. submarginalis, but not in O. flexuosellus.

新西兰蟹科(鳞翅目:Pyraloidea)的时空性别比偏差和Wolbachia感染。

新西兰的蛾类动物(Pyraloidea)主要由特有物种组成。在2017年和2018年期间,在14个地方收集了1,749个人中的56种Pyraloidea。筛选了所有物种的Wolbachia感染,其中八种(14%)的标本为阳性,其中六种属于S科。这是新西兰鳞翅目中Wolbachia感染的第一个记录。分析了最常见的拟吡喃类物种,近缘的Eudonia submarginalis和Orocrambus flexuosellus,以寻找更大的个体,寻找性别比和Wolbachia感染。在这两个物种中,女性均存在性别比例偏见,但其时空变化。沃尔巴克氏菌存在于所有近缘性大肠杆菌中,根据地区的不同,有10%至80%的被测个体为阳性。在屈挠曲霉中未发现Wolbachia感染。因此,性别比偏倚可能与潜伏性大肠杆菌中的Wolbachia感染有关,而与弯曲柔肠杆菌无关。
