Classical Biological Control of Saltcedar (Tamarix Spp.) in Oklahoma

Pages : 99
Book Description
Saltcedar (Tamarix spp.) covers nearly 86,000 acres in Oklahoma mostly in the western third of the state. A beetle, Diorhabda carinulata (Coleoptera: Chrysomellidae) has been released in nine western states as a biological control agent. The U.S. Fish and Wildlife Service asked that we attempt to introduce the beetle into the Great Salt Plains Wildlife Refuge in Oklahoma, which is infested with saltcedar. We surveyed three saltcedar stands (Lake site, Highway site, Marsh site) from 2009-2010 at the refuge that were selected for their unique ecological characteristics. Our objectives were to compare two sampling methods (vacuum and beat stick) for their capability to assess the diversity of insect predators in different saltcedar-dominated habitats and identify potential arboreal predators of D. carinulata. The results of the survey indicated that several arthropod predators were abundant enough to potentially effect the establishment of D. carinulata. Comparison of insect assemblages between sampling methods revealed that the vacuum sampling technique recovered more overall taxa but neither method recovered all taxa present highlighting the importance of employing multiple sampling methods. The most common insect predators collected were Coccinella septempunctata (Coleoptera: Coccinellidae) in 2010 vacuum samples and Zelus tetracanthus (Hemiptera: Reduviidae) in 2009 vacuum and 2010 beat stick samples. Diversity indices (Shannon Diversity Index and Simpson Diversity Index) indicated that the Lake Site habitat was consistently more species rich than the Highway and Marsh Site. Two coccinellids, C. septempunctata and Hippodamia convergens, were identified as common predators present. We selected these two species for additional lab studies designed to evaluate the suitability of eggs and larvae of D. carinulata as a food source for the adults and larvae of both coccinellids. The studies revealed that D. carinulata is neither a suitable nor an acceptable food source for larval stages of both beetles. Adult lady beetles of both species attacked eggs and first instar D. carinulata larvae, but only one attack was recorded on a D. carinulata life stage beyond first instar. These results indicate that adult C. septempunctata and H. convergens could prove to be a limited predator of D. carinulata eggs and first instar larvae.
