Natural enemies of Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) and their population fluctuations in Ahvaz, southwest of Iran
The pink hibiscus mealybug <em>Maconellicoccus hirsutus </em>(Green)<em> </em>(Hemiptera: Pseudococcidae) is a serious economic pest in tropical and subtropical regions and causes damage to many agricultural, forestry and greenhouse crops. In order to identify the natural enemies of this pest, bi-weekly samplings were done in infested areas of Ahvaz, located at southwest Iran during 2011-2012. Samples were also taken from Chinese hibiscus shrubs, <em>Hibiscus</em> <em>rosa-sinensis</em> L. at two urban areas in Ahvaz to determine the pest population fluctuations. Other infested plants were also sampled for <em>exploring </em><em>natural enemies</em><em> </em>associated with <em>M. hirsutus</em>. The identified natural enemies in this study are as follows: <em>Nephus arcuatus</em> Kapur, <em>Hyperaspis polita</em> Weise, <em>Hyperaspis vinciquerrae</em> Capra, <em>Exochomus nigripennis</em> Erichson, <em>Scymnus</em> (<em>Pullus</em>) <em>syriacus</em> Marseul (Col., Coccinellidae) –<em> Chrysoperla carnea</em> (Stephens) (Neu., Chrysopidae) –<em> Anagyrus</em> sp. (Hym., Encyrtidae). Also one parasitoid of coccinellid larvae and three species of hyperparasitoids were identified as follows: <em>Homalotylus quaylei</em> Timberlake (parasitoid of coccinellid larvae), <em>Prochiloneurus aegyptiacus</em> (Mercet), <em>Prochiloneurus bolivari</em> Mercet (Hym., Encyrtidae) and <em>Chartocerus kurdjumovi</em> (Nikol’skaya) (Hym., Signiphoridae). The coccinellid <em>H. vinciquerrae</em> is new to the fauna of Iran. The natural enemies, i.e. <em>N. arcuatus </em>and <em>Anagyrus</em> sp. had the highest populations on the host plants throughout the year.
