Abstract

Abstract: This paper aims at addi information about the biology of aphids (Aphis gossypii Glover) (Hemiptera: Aphididae). A. gossypii biological information include: 1). Imago A. gossypii have winged and wingless. A. gossypii have cauda pale somewhat blackish and two or three pairs of setae hair and have tubercles head apart, front head is relatively flat and there is no protrusion at the base of the antenna. The cornicles of A. gossypii dark color, relatively short and black. A. gossypii have antennae shorter than its body length.

The eggs are laid on average amounted to 5 eggs per day for 16-18 days. 2). A. gossypii is fitofag cosmopolitan insects which are found in the tropics, subtropics and temperate. A. gossypii have host plants of various families of plants around the world such as Asteraceae, Acanthaceae, Myrtaceae, Solanaceae, Moraceae, Araceae, boraginaceae, Cucurbitacae, Verbenaceae, Sterculiaceae, Rubiaceae, Malvaceae, musaceae, Piperaceae, portulacaceae, Rosaceae, Apocynaceae, Labiatae, Urticeae and Apocynaceae '
