    Introductions for Biological Control in Hawaii 1997–2001
    (Hawaiian Entomological Society, 2003-11) Culliney, Thomas W. ; Nagamine, Walter T. ; Teramoto, Kenneth K.
    Introductions and releases of natural enemies for the biological control of agricultural and forest pests in Hawaii are discussed for the period 1997-2001. Sixteen insect and five fungal species were introduced, released, or redistributed by the Hawaii Department of Agriculture for the control of six weeds (Clidemia hirta, Coccinia grandis, Miconia calvescens, Myrica faya, Senecio madagascariensis, and Ulex europaeus) and four insect pests (Aleurocanthus woglumi, Bemisia argentifolii, Pentalonia nigronervosa, and Sipha flava).

    Nontarget Arthropods Captured in Cue-lure Baited Bucket Traps at Area-Wide Pest Management Implementation Sites in Kamuela and Kula, Hawaiian Islands
    (Hawaiian Entomological Society, 2003-11) Uchida, Grant K. ; McInnis, Donald O. ; Vargas, Roger I. ; Kumashiro, Bernarr R. ; Jang, Eric
    An area-wide integrated pest management (AWPM) program began in the Hawaiian Islands in October, 1999 to demonstrate the feasibility of suppressing populations of three economically important species of fruit flies (oriental fruit fly (Bactrocera dorsalis (Hendel), melon fly (Bactrocera curcurbitae (Coquillett), and Mediterranean fruit fly (Ceratitis capitata (Wiedmann)). Past concerns in Hawaii about the impact of fruit fly lures on nontarget species, especially endemic Hawaiian species, have prompted research on methyl eugenol and protein hydrolysate bait. The objective of this study was to collect, identify, and categorize field-collected nontarget arthropods captured in cue-lure baited bucket traps in the AWPM implementation sites. Attraction of nontarget species to cue-lure baited traps shows a need for future improvements in trap design.

    Preliminary Field Tests on the Suitability of Amdro and Distance in Ant Bait Container for Control of the Big-Headed Ant, Pheidole megacephala (Hymenoptera: Formicidae)
    (Hawaiian Entomological Society, 2003-11) Taniguchi, Glenn Y. ; Ota, Asher K. ; Kawate, Michael K. ; Rohrbach, Kenneth G. ; Uchida, Grant K.
    Studies were conducted to (1) select a suitable brand of bait container for use in the control of big-headed ant in an agricultural situations, (2) determine the short-term effects environmental conditions on the potency of Amdro in a suitable bait container, and (3) to compare the effectiveness under field conditions of various spacings of bait containers using Distance and Amdro in sequence. Perimeter Patrol System bait container was selected as the most suitable for field use based on the capacity to contain sufficient amounts of Amdro, lower cost, smaller size, low profile shape, and ease of handling. Potency of Amdro was retained in the Perimeter Patrol System container for a period of twelve weeks. Bait containers spaced at 15.24 m apart in a field plot had the best control compared with 7.62 and 30.48 m spacings.

    Fortuitous Introduction of Two Natural Enemies of Lantana camara to Chuuk
    (Hawaiian Entomological Society, 2003-11) Muniappan, R. ; Reddy, G.V.P.
    Ophiomyia lantanae (Froggatt) and the Calycomyza lantanae Frick were recorded from Lantana camara L. in Chuuk Islands. Both of these agromyzids are native to tropical Americas and were not intentionally introduced and this is the second report of fortuitous introduction of natural enemies of L. camara in to the Chuuk State possibly from Pohnpei State within the Federal States of Micronesia.

    Uroleucon formosanum (Takahashi) (Homoptera: Aphididae) Found on Youngia japonica (L.) DC on Guam and Rota in the Mariana Islands
    (Hawaiian Entomological Society, 2003-11) Miller, R.H. ; Idechiil, O. ; Foottit, R.G ; Pike, K.S.
    Uroleucon formosanum (Homoptera: Aphididae) was collected from Asiatic (Oriental) hawksbeard, Youngia japonica, on Guam and Rota in 2003. These collections constitute a significant range expansion for U. formosanum into the western Pacific region. The aphid and its host plant were likely accidentally introduced to the islands in cargo or by travelers returning from known host regions in eastern Asia and Japan.
