Abstract
Information on the rice root aphids in Indonesia relatively little is known. A survey to collect the root aphids on some rice varieties was conducted in 2014-2015 in West Java Province, Indonesia. The collected specimens were carried to the laboratory for further morphological character observation and species identification. There were two aphids identified as Rhopalosiphum rufiabdominale (Sasaki) and Tetraneura nigriabdominalis (Sasaki) collected from rice varieties of Ciherang, IR-64, Cisadane and Rojolele. The rice root aphid R. rufiabdominale is oval-shaped body, reddish or greenish brown body colours, body length of 2.0-2.6 mm, antennae 5 segmented with antennal hairs long, antennal tubercle not clearly visible and terminal process more than 3 times longer than base, femur and siphunculi are dark brown or black, cauda shorter and darker than siphunculi. While T. nigriabdominalis has a body colour of red or brownish red and body like gall. Body length is 1.4-2.3 mm, the antenna terminal shorter than base antenna, the legs short, siphunculi like ring or pore shaped, and body hairs long. Both root rice aphids were found in these nine districts of the rice central production in Bandung, Bogor, Cianjur, Cirebon, Garut, Karawang, Kuningan, Sukabumi and Tasikmalaya. Rhopalosiphum rufiabdominale was collected from difference altitudes from 12 to 1.438 m above sea level (asl), while T. nigriabdominalis was collected from area below 1.000 m a.s.l. The results of this study indicate that both R. rufiabdominale and T. nigriabdominalis have a wide range of host rice varieties and vertical distribution from low land to high land.
