A preliminary list of the Odonata of Wayne Co
... Wayne County is heavily urbanized. When I began surveying its Odonata in 2000, there were only 43 species confirmed by specimens (Craves 2002). L. vibrans represents the 40th new county record I have confirmed since that time, demonstrating how much we have to learn about Odonata distribution even in previously well-surveyed, urbanized areas with limited habitat. ...
Egg parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) have been successfully utilized for biocontrol of several lepidopteran pests world-wide. The age specific fecundity of Trichogramma brassicae Bezdenko and Trichogramma cacoeciae Marchal using Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) as host were determined at 20, 26, and 30°C and 60-70 % R.H. in the laboratory. Both T. cacoeciae and T. brassicae demonstrate high parasitism ability and intrinsic rates of increase on E. kuehniella and had a similar response to increasing temperature.

Libellula vibrans Fabricius (Odonata: Libellulidae) is a large dragonfly previously known in Michigan only from sight or literature records. In 2005, two small populations were found in Wayne County, Michigan. ____________________ Libellula vibrans Fabricius (Odonata: Libellulidae), the Great Blue Skim-mer, is not mentioned in historical lists of Michigan Odonata (Byers 1927, Kormondy 1958, O'Brien 1997). Prior to 2005, there are no specimens in the University of Michigan Museum of Zoology's (UMMZ) insect collection, where voucher specimens from the Michigan Odonata Survey (MOS) are housed. A published report of L. vibrans for Michigan was by Nishida (1999) find-ing one individual on 22 June 1995 at a small wooded wetland in Westland, northwestern Wayne Co., Michigan. His paper also includes a photograph of a male from this location dated 10 July 1995. If he obtained a specimen, its whereabouts are unknown. A report of a sight record from Wayne County from 1999 (Hudson et al. 1999), as well as two sight reports from Washtenaw County from early July 2005 (M. F. O'Brien, pers. comm.) prompted me to search for this species, focusing on the Westland area. On 9 July 2005, Darrin O'Brien and I observed a single male in a small wooded swamp in the Holliday Nature Preserve in Westland, Wayne County, Michigan. As Westland is a highly developed suburb of Detroit, I believe this is the same spot in which Nishida (1999) made his observations; in fact, I checked this spot periodically in 2003 searching for L. vibrans. The site itself is a wooded wetland of less than one hectare. About 20% of the site is open water, and the rest liberally interspersed with buttonbush (Cephalanthus occidentalis) and many fallen trees. Water is shallow, probably not more than a half-meter deep in wet years, and is covered by duckweed (Lemna sp.) by mid-summer. Water overlays thick organic muck which also lines the shore. The wetland is situated in an ~40 ha forest fragment that is part of a larger (200-ha), somewhat linear forest preserve in northwestern Wayne County. We were able to clearly observe a male L. vibrans on our initial observation on 9 July but it flew off and could not be relocated. We returned the following day and made a systematic search of the area. After a half-hour, we located three to five male L. vibrans, characteristically hunting from perches in dappled shade and allowing close approach (Dunkle 2000, Abbott 2005). We took two voucher specimens which have been deposited in the Insect Collection at the UMMZ. Coincidentally, this was ten years to the day that Nishida photographed a male in what is presumably the same spot. On 29 August 2005, O'Brien and I were able to access another small (<2 ha) wooded pond on the north end of Willow Metropark, located in southwestern Wayne County, and ~20 km nearly due south of the Westland site. Earlier in the season this pond had been too wet for close approach. By late August, the pond itself had areas of standing water only a few centimeters deep surrounded by soft muck becoming overgrown with wetland plants such as Lobelia cardina-lis and Polygonum coccinea. The area is ringed by forest and connected by an intermittent stream to the Huron River, <100 m away. We immediately saw 92 THE GREAT LAKES ENTOMOLOGIST Vol. 39, Nos. 1 & 2 several male L. vibrans perched on fallen trees overhanging the pond. When one would fly close to another, they would give chase but not far or vigorously. We took one voucher for this location. DISCUSSION Libellula vibrans has been recorded in 28 states and the province of On-tario. It is most common in the southeastern U.S. and southern Atlantic coast (Needham et al. 2000, Donnelly 2004). In Wisconsin, it is a species of special concern, represented only by historical records (~100 years old) from the Mil-waukee area (Smith et al. 2004). There are 25 specimens (22 from Cook Co.) in the Illinois State Museum from the northern third of Illinois (ISM 2003). The species is considered uncommon in Indiana with records for 15 counties (Curry 2001). The status in Ohio is uncommon and limited (Glotzhober and McShaffrey 2002). Its status in the northeastern part of the state is rare (Rosche 2002). There are only six records in Ontario, all from Essex and Kent counties in the extreme southwestern part of the province (OOA 2005). This is a species that would be difficult to overlook, being the largest libellulid in North America, with a total length of 56-63 mm (Needham et al. 2000). Female L. vibrans might be mistaken for female L. incesta Hagen, Slaty Skimmer, which is 50-52 mm long; however, the white face of both sexes of L. vibrans distinguishes it from the darker faces of the other species (Needham et al. 2000, Abbott 2005). Wayne County is heavily urbanized. When I began surveying its Odonata in 2000, there were only 43 species confirmed by specimens (Craves 2002). L. vibrans represents the 40th new county record I have confirmed since that time, demonstrating how much we have to learn about Odonata distribution even in previously well-surveyed, urbanized areas with limited habitat.
complete as of December, 2013 The Great Lakes Region includes the states and Canadian provinces that drain into the Great Lakes. For this bibliography, The Great Lakes – Superior, Michigan, Huron, Erie, and Ontario comprise a large area of freshwater unrivalled by anywhere else. The Odonata fauna has been studied in the region for over 150 years, and the body of literature is substantial enough to warrant its own bibliography. I purposely left out papers that dealt specifically with faunas not influenced by the Great Lakes, such as SE Pennsylvania and SE New York. It is as complete as I can make it, and if you see significant omissions, please contact me. An annotated list of new seasonal and county records for Ohio Dragonflies (Odonata).

During 1994-1995 extensive field work was conducted in southeastern Michigan in an attempt to assess the species population and composition of libellulid dragonflies. Additional field work was conducted on dragonflies from southwestern Ontario migrating into southeastern Michigan. Comparisons were mode with the species listed for this area 37 years earlier in Kormondy (1958) anticipating changes due to wetland reductions and the effects of pesticides. With one exception, all species listed in Kormondy were observed. Additionally, one species, unknown from this area as of 1958, was encountered.
A part of the connecting channel system between Lake Huron and Lake Erie, the Detroit River forms an integral link between the two lakes for both humans and biological resources such as fish, nutrients, and plant detritus. This profile summarizes existing scientific information on the ecological structure and functioning of this ecosystem, river hydrology, lower trophic-level biotic components, native and introduced fishes, waterfowl use, ecological interrelationships, commercial and recreational uses of the river, and current management issues. Despite urbanization, the river still supports diverse fish, waterfowl, and benthic populations. Management issues include sewer overflows; maintenance dredging for navigation and port activities; industrial discharges of potentially hazardous materials; and wetland, fishery, and waterfowl protection and enhancement. 210 refs., 30 figs., 41 tabs.
