TOXOPTERA CITRICIDA (HOMOPTERA: APHIDIDAE) AT FIVE TEMPERATURES YONG XUE DENG AND JAMES H. TsAI Fort Lauderdale Research and Education Center, IFAS, University of Florida 3205 College Avenue, Fort Lauderdale, FL 33314 ABSTRACT The brown citrus aphid (BrCA), Toxoptera citricida (Kirkaldy), a newly introduced 1 Development and survivorship of Coelophora inaequalis (F.) were evaluated in the laboratory on the brown citrus aphid, Toxoptera citricida (Kirkaldy) at 20 and 25 °C.Coelophora inaequalis could complete its life cycle feeding on T. citricida at these two temperatures. They development colonies on young growing tips of the citrus trees. The brown citrus aphid, Aphis (Toxoptera) citricidus (Kirkaldy), is an important citrus pest with a global presence and is the most important vector of the Citrus tristeza virus (CTV) within its distribution area. The melon, or cotton, aphid (Aphis gossypii) is green to black. We reconstruct sets of coding sequences (CDSs) and compute sets of putative ortho-logues between aphid species. Larvae of the lacewing Chrysoperla plorabunda (Fitch) were evaluated in laboratory and field tests for potential to control the brown citrus aphid, Toxoptera citricida (Kirkaldy) in inundative releases. The brown citrus aphid, Toxoptera citricida (Kirkaldy) (Hemiptera: Aphididae), is an important citrus pest and the main vector of Citrus tristeza virus (CTV) worldwide. CTV is spread by aphids; those that are most important are Toxoptera citricida (brown citrus aphid), Toxoptera aurantii (black citrus aphid), Aphis gossypii (cotton or melon aphid) and Aphis spiraecola (green citrus aphid). Influence of different temperatures (20-35°C) , moisture (relative humidities, 12, 52, 75 and 98%) and larval densities (100, 400, 600, and 1000) on the development time and mortality of the Musca domestica as well as impact of the survival rate, longevity, fecundity and fertility of adult M. domestica at temperatures (20-35°C) was studied. Abstract. 24 Tristeza Virus Citrus Through aphid (Toxoptera citricida) Yellowing of terminal shoots in plants; there is stem pitting Growth and yield are affected. The disease can kill the citrus plants. The life cycle of brown citrus aphid is much less complex Description and Life Cycle (Back to Top) Adults: Tamarixia radiata adults are small black wasps (0.92 to 1.04 mm long) with widely separated eyes. Development and survivorship of Coelophora inaequalis (F.) were evaluated in the laboratory on the brown citrus aphid, Toxoptera citricida (Kirkaldy) [Toxoptera citricidus] at 20 and 25°C. Control by budding plants on Cleopatra tangerine, lake and Sampson. Tangelo stocks and rough lemon 7.3 Nature and Effect of Disease Damage to Crop We quantify the fraction of The typical life cycle for this pest is: Egg —> Larva —> Pupa —> Adult. Aphis spiraecola was first described by Patch in 1914. Details please check this Black Citrus Aphid page. The life cycle of T. citricida is linked to the phenology of plants belonging to the genus Citrus (Michaud, 1998; Uygun et al., 2012). in the life cycle of the specific pests for maximum suppression. Introduction. Tangelo stocks and rough lemon The wings are hyaline with pale yellow veins. Sexual dimorphism is … The brown citrus aphid, Toxoptera citricida (Kirkaldy), is considered the primary vector of citrus tristeza virus, a severe pathogen which causes los Infested citrus terminals were sampled repeatedly in a non-destructive manner and data recorded on the recruitment of natural enemies and the fate of aphid colonies. Peak populations are found in the middle of summer. The beetle can overwinter as an egg, a larva or a pupa. ... Toxoptera citricida, with the objective of identifying what virus-encoded proteins it uses to interact with the vector. 24 Tristeza Virus Citrus Through aphid (Toxoptera citricida) Yellowing of terminal shoots in plants; there is stem pitting Growth and yield are affected.
