Denticle rows on larval appendages in twelve species of Phytoseiidae (Parasitiformes: Mesostigmata)

Abstract The presence of denticles on appendages such as the palpi and legs is rarely documented in phytoseiid mite larvae. To address this gap, we studied twelve species across six genera of Phytoseiidae: Amblydromalus limonicus, Amblyseius herbicolus, Amblyseius orientalis, Amblyseius taiguensis, Euseius utilis, Neoseiulus benjamini, Neoseiulus californicus, Neoseiulus setarius, Neoseiulus womersleyi, Neoseiulus zwoelferi, Phytoseiulus persimilis and Phytoseius hongkongensis. We identified and described the denticles on the palp, basis capitulum, and specific leg segments of these species, discussing their functional significance.
