Özet
Description, distribution, host plants, type of damage and natural enemies of Pseudococcus cryptus Hempel (Hemiptera: Pseudococcidae) were revealed in Hatay citrus plantations. Citrus plantations were infested by P. cryptus at the ratios of 55.78%, 14.67%, 11.63% and 30.61% in Antakya, Dortyol (Payas), Iskenderun and Samandag, respectively in 2010, whilst only Samandag was infested at 15.43%, in 1997. Seventeen species belong to 11 families were determined as host plants of P. cryptus. Active stages of P. cryptus, causes honeydew during sucking the plant juice from leaves, twigs, fruits and trunks of citrus trees. Damage to citrus trees has been associated with leaves and fruit drops, with unsightely apperance of fruits due to severe honeydew on which sooty mold develops. Cunaxa pothensis Den Heyer, Nephus includens Kirsch., N. (Sidis) heikei, N. (Sidis) caneparii, N.nigricans, Oenopia (Synharmonia) conglobata (L.), Scymnus (Pullus) araraticus Khnzorian, S. (P.) subvillosus, S. (P.) flagellisiphonatus, Cryptolaemus montrouzieri Mu Is., Chilocorus bipustulatus L., Exochomus quadripustulatus L., Cardiastethus nazarenus Reuter, Sympherobius (S.) fallax Navas, Dichochrysa prasina (Burmeister), Chrysopa viridana Schneider and Chrysoperla carnea (Stephens) were found as predatory species. Parasitoids of P. cryptus were Anagyrus pseudococci Gir., Leptomastidea abnormis Gir., Clausenia purpurea Ishii and Pachyneuron muscarum L. Quarantine measures should be emphasized to prevent the dispersion of the pest to citrus plantations where P. cryptus is not known to occur. In infested areas, release and/or establishment of the main natural enemies, C. purpurea and C. montrouzieri would be recommended; meanwhile application of broad spectrum pesticides should be avoided.
