Top of page In the Aphis frangulae group to which A. gossypii belongs, the primary (winter) hosts belong to the Rhamnaceae; A. gossypii is an exception as it can also overwinter on a number of plants in other families. 5) and vary in color from watery white to green. roung stages and the apterous females are not at first easy todistinguish from A. gossypii, but the apterous females are darker andhave a shining reddish or brownish-black appearance, while those ofgossypii are deep greenish in color and have the cauda very much cut.. It is common in North and South America, Central Asia, Africa, Australia,[3] Brazil, East Indies, Mexico and Hawaii and in most of Europe. Also called the melon aphid it is commonly associated with outbreaks on cotton in the Southeast. Antennal olfaction, which is extremely important for insect survival, mediates key behaviors such as host preference, mate choice, and oviposition site selection.

The winglessform is about one-fifteenth inch long and varies from light yellowor tan colored to deep olive-green or deep green which appearsalmost blackish, the abdomen being always more or less mottled.The rather long, tapering, honey-tubes are jet black, and the legsand antennae pale whitish-yellow. Identification and expression pattern of candidate olfactory genes in Chrysoperla sinica by antennal transcriptome analysis. Aphis gossypii is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. [3] These mature in about twenty days at 10 °C and in about four days at 30 °C. (Aphis (Fig. Typically, the overwintering host is the plant where eggs are laid and the aphid completes a sexual reproductive phase.
