A review of the aphid genus Macrosiphoniella del Guercio, 1911 (Hemiptera: Aphididae) in the USA with description of a new species

Abstract

Here we present a review of the 18 species of the Macrosiphini genus Macrosiphoniella (Hemiptera: Aphididae) known to occur in the United States of America, representing two subgenera, Macrosiphoniella and Phalangomyzus Börner, 1939. We report key features for all species including colour in life and pigmentation on slides of apterous and alate viviparous females of all 18 species. Distributional data, host plants, and biological notes of the reviewed species are presented. Apterous, alate and oviparous females of a new native USA species, Macrosiphoniella sunshine sp. nov., associated with Eriophyllum lanatum (Asteraceae) are described from specimens collected in California, Oregon, and Washington. Keys to apterous and alate viviparous females of the Macrosiphoniella in the USA are also provided.

Identification and Expression Analysis of Chemosensory Genes in the Antennal Transcriptome of Chrysanthemum Aphid Macrosiphoniella sanborni

“…The aphid genus Macrosiphoniella includes about 159 recognized species, which mainly feed on various Asteraceae, mostly Artemisia, Achillea, Aster, Chrysanthemum and Helichrysum [1].…”

“…The chrysanthemum aphid Macrosiphoniella sanborni (Hemiptera: Aphididae) is a major destructive oligophagous pest for chrysanthemums. Chrysanthemum aphids not only rob nutrients and damage the host plants directly but also act as severe chrysanthemum virus vectors (e.g., vein mottle and virus B) [ 1 ]. Much time, money and energy have been invested in controlling this pest, and the utilization of pesticides has been the most critical and practical pathway until now.…”

“…The aphid genus Macrosiphoniella includes about 159 recognized species, which mainly feed on various Asteraceae, mostly Artemisia , Achillea , Aster , Chrysanthemum and Helichrysum [ 1 ]. No previous study has reported on the antennal transcriptome of this genus, and little is known about its olfactory molecular basis.…”
