Pengujian kekhususan inang parasitoid Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) pada empat spesies kutu putih yang berasosiasi dengan tanaman singkong

A parasitoid, <em>Anagyrus lopezi</em> (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to control the cassava mealybug <em>Phenacoccus manihoti</em> Matile-Ferrero (Hemiptera: Pseudococcidae). To determine its potential uses an...

To determine its potential uses and effect on non-target species, behavioural observation of the parasitoids were made on four species of mealybugs, i.e. <em>P. manihoti</em>,<em> Paracoccus marginatus</em> Williams-Granara de Willink,<em> Pseudococcus jackbeardsleyi</em> Gimpel-Miller, and <em>Ferrisia virgata</em> Cockerell (Hemiptera: Pseudococcidae). For that purposes, a set of tests were conducted wich includes host susceptability, preference, and suitability. Tests were conducted by exposing a female parasitoid to 3rd instar nymphs of each mealybug species in a petri dish. For susceptability test, parasitoid <em>A. lopezi</em> encounterend <em>P. manihoti</em> more often (13.70 ± 7.18 visits per 30 minutes) as compared to <em>P. marginatus</em> (985 ± 10.24),<em> P. jackbeardsleyi</em> (6.60 ± 3.62), and <em>F. virgata</em> (5.75 ± 4.09). So did ovipositor probing occurred more on <em>P. manihoti</em> (8.20 ± 5.68 probes per 30 minutes) than on <em>P. marginatus</em> (0.70 ± 1.84),<em> P. jackbeardsleyi</em> (0.35 ± 0.68), and<em> F. virgata</em> (0.10 ± 0.45). For preference test, host encounter and ovipositor probing by the parasitoid were more common on <em>P. manihoti</em> as opposed to other mealybug species. Out of four mealybug species tested,<em> P. manihoti</em> was the only suitable host for parasitoid development, with the number of progenies emerged 7.40 ± 2.17 individuals per 3 female parasitoids exposed in 24 hour. Host specifity exhibited by parasitoid <em>A. lopezi</em> may prevent adverse effect to other mealybug species inhabiting cassava fields.Rani Dessy KaryaniNina MaryanaAunu RaufThe Entomological Society of IndonesiaarticleAnagyrus lopezi, host specifity, mealybug, parasitoid, Phenacoccus manihotiZoologyQL1-991ENIDJurnal Entomologi Indonesia, Vol 13, Iss 1 (2016)
