    Harmful Non-Indigenous Species in the United States September 1993 OTA-F-565 NTIS order #PB94-107679 GPO stock #052-003-01347-9 Recommended Citation: U.S. Congress, Office of Technology Assessment, Harmful Non-Indigenous Species in the United States, OTA-F-565 (Washington, DC: U.S. Government Printing Office, September 1993). For Sale by the U.S. Government Printing Office ii Superintendent of Documents, Mail Stop, SSOP. Washington, DC 20402-9328 ISBN O-1 6-042075-X Foreword on-indigenous species (NIS)-----those species found beyond their natural ranges—are part and parcel of the U.S. landscape. Many are highly beneficial. Almost all U.S. crops and domesticated animals, many sport fish and aquiculture species, numerous horticultural plants, and most biologicalN control organisms have origins outside the country. A large number of NIS, however, cause significant economic, environmental, and health damage. These harmful species are the focus of this study. The total number of harmful NIS and their cumulative impacts are creating a growing burden for the country. We cannot completely stop the tide of new harmful introductions. Perfect screening, detection, and control are technically impossible and will remain so for the foreseeable future. Nevertheless, the Federal and State policies designed to protect us from the worst species are not safeguarding our national interests in important areas. These conclusions have a number of policy implications. First, the Nation has no real national policy on harmful introductions; the current system is piecemeal, lacking adequate rigor and comprehensiveness. Second, many Federal and State statutes, regulations, and programs are not keeping pace with new and spreading non-indigenous pests.

Entomol. 116: 302–308, 2019 http://www.eje.cz doi: 10.14411/eje.2019.033 ORIGINAL ARTICLE Cannibalism among same-aged nymphs of the omnivorous predator Dicyphus errans (Hemiptera: Miridae) is affected by food availability and nymphal density KONSTANTINA ARVANITI 1, ARGYRO FANTINOU 2 and Dionyssios PERDIKIS 1 1 Laboratory of Agricultural Zoology & Entomology and 2 Laboratory of Ecology & Environmental Sciences, Agricultural University of Athens, Iera Odos 75, 118 55, Athens, Hellenic Republic; e-mails: [email protected], [email protected], [email protected] Key words. Hemiptera, Miridae, Dicyphus errans, adult weight, cannibalism, density, development, food availability, omnivorous predator Abstract. Cannibalism, the act of eating an individual of the same species has been little studied in omnivorous insect predators. Dicyphus errans (Wolff) (Hemiptera: Miridae) is a generalist omnivorous predator that commonly occurs in tomato greenhouses and fi eld crops in the Mediterranean basin. In this work cannibalism among same-aged neonate nymphs of D. errans was studied when 1, 2, 4, 8 or 16 individuals were placed in a Petri dish along with or without heterospecifi c prey. Although nymphs were un- able to complete their development in the absence of prey they survived longer when there were initially 2 individuals per dish than in any other treatment including a single individual. This may indicate that cannibalism in this predator has positive effect on nymphal survival, which however was not the case at higher densities. The presence of heterospecifi c prey increased nymphal survival and individuals were as equally successful in completing their development as when kept singly.

Simple Summary: Biological control (BC) is an effective way to regulate pest populations in hor- ticultural crops, allowing the decrease of pesticide usage. On tomato, predatory insects like plant bugs or mirids provide BC services against several insect pests. Native predators are adapted to local conditions of climate and ecology and therefore may be well suited to provide BC services. Dicyphus cerastii is a predatory mirid that is present in the Mediterranean region and occurs in tomato greenhouses in Portugal. However, little is known about its contribution to BC in this crop. In this study, we evaluated how prey consumption is affected by increasing prey abundance on four different prey, in laboratory conditions. We found that the predator can increase its predation rate until a maximum is reached and that prey characteristics like size and mobility can affect predation.
