Distribution of \u3ci\u3eEutarsopolipus\u3c/i\u3e (Acari: Podapolipidae) and \u3ci\u3eCrotalomorpha Camini\u3c/i\u3e (Acari: Crotalomorphidae), Ectoparasites of Stenolophus (Coleoptera: Carabidae) in Michigan, U.S.A.
Three acarine parasites of Stenolophus spp are described from Michigan. Eutarsopolipus elzingai Husband (Acari: Podapolipidae), previously known from eastern Kansas, Eutarsopolipus brevichelus Husband and Husband, with one Michigan record, and Crotalomorpha camini Lindquist and Krantz (Acari: Crotalomorphidae), previously known from Kansas, Nebraska, Arkansas and Oklahoma, are widely distributed in Michigan as subelytral parasites of Stenolophus comma (Fabricius) (Coleoptera: Carabidae) and Stenolophus lecontei (Chaudoir), the seed corn beetle. Eutarsopolipus elzingai and E. brevichelus may occur occasionally on the same host beetle
Distribution of Crotalomorphidae and Podapolipidae (Acari: Heterostigmata), Ectoparasites of Stenolophus (Coleoptera: Carabidae) in North America
Eutarsopolipus elzingai Husband (Tarsonemoidea: Podapolipidae), parasitic on Stenolophus comma (Fabricius) and Stenolophus lecontei (Chaudoir) (Co- leoptera: Carabidae) is reported from southern Canada and the United States from Oregon to Maine and from Michigan to North Carolina. Eutarsopolipus brevichelus Husband and Husband is distributed east of the Rocky Mountains in southern Canada and in the United States from Colorado to Virginia and from Michigan to Louisiana. Crotalomorpha camini Lindquist and Krantz is reported from Kansas and Nebraska east to Massachusetts and from Michigan to Arkansas. Hosts for E. brevichelus and C. camini are S. lecontei and S. comma. Stenolophus fuliginosus (Dejean) is a new host for E. brevichelus in New Brunswick, Canada. S. maculatus (Leconte) in Oregon and S. lineola (Fabricius) in southern California, U.S.A. are newly reported hosts of E. elzingai
A New Species of \u3ci\u3eCaraboacarus\u3c/i\u3e (Acari: Caraboacaridae) From \u3ci\u3eCalosoma Argentinense\u3c/i\u3e (Carabidae) From Chile
Caraboacarus calosomae n. sp is described from Calosoma argentinense Csiki collected in Santiago, Chile. This is the first record of this genus in South America. The genius is recorded from North America, Europe, Asia. and Guadalcanal Island in the Pacific Ocean
\u3ci\u3eEutarsopolipus Hemistylus\u3c/i\u3e Sp. Nov. (Acari: Podapolipidae), Subelytral Parasite of \u3ci\u3eChlaenius Prasinus\u3c/i\u3e Dejean (Coleoptera: Carabidae) From Central and Eastern USA
Eutarsopolipus hemistylus sp. nov. (Acari: Podapolipidae), subelytral, parasite of Chlaenius prasinus Dejean, 1826 (Coleoptera: Carabidae), is described from Illinois, Ohio, Missouri, Kentucky, North Carolina and Georgia, USA. E. hemistylus is compared with E. americanus Husband and Husband 2013 described from the same host, C. prasinus, collected in Michigan and Missouri. Species in the myzus group of Eutarsopolipus that parasitize beetle species of the genera Chlaenius, Poecilus, Scarites and Diplocheila are noted. Including a species from Japan currently under study, E. hemistylus is one of 8 species in the myzus group with adult females with stylets exceeding 43 micrometers but less than 90 micrometers
A New \u3ci\u3eEutarsopolipus\u3c/i\u3e (Acari: Podapolipidae); Parasite of \u3ci\u3eHarpalus Herbivagus\u3c/i\u3e (Coleoptera: Carabidae) From Michigan
Eutarsopolipus porteri n. sp. (Acari: Podapolipidae) is described from HarpaIus herbivagus and E. elongatus is reported for the first time in North America from Amara aenea (Coleoptera: Carabidae) from Fort Custer State Recreation Area, Kalamazoo County, Michigan. Of the 7 species of Podapolipidae known from American Carabidae, E. elongatus was introduced with Amara aenea and the others are native species. All are parasites restricted to Carabidae
Ovacarus Peellei, a Nre Species of Mite (Acarina: Podapolipidae) Associated with the Carabid Pasimachus Elongatus
Recently, a new genus and species of rnite was discovered in association with the vaginal membrane or aedeagus of Clivina impressifrons, a pest which damages corn seed and seedlings in the midwest (Stannard and Vaishampyan 1971). This mite, Ovacarus clivinae, was described as a monotypic species of the genus Ovacarus. In the process of examining another midwestern carabid beetle, Pasimachus elongatus LeConte, an undescribed species of Ovacarus was discovered. Larviform females were found near the external genitalia. All stages were found associated with oviducts and vaginal membranes, in a manner similar to that described by Stannard and Vaishampayan (1971). The new mite is here described as Ovacarus peellei
Observations on Colony Size in Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.)
(excerpt)
One factor to consider when attempting to rear bumblebees (Bombus spp.) for pollination of crops is potential colony size. Species which emerge from hibernation early and continue to produce workers late in the summer or early fall are likely to have larger colonies. In contrast, Arctic species such as Bombus polaris Curtis and hyperboreus Schonherr may produce only one brood prior to the sexual brood. Richards (1973) reported that colonies of polaris are smaller than colonies of species from lower latitudes in North America. Hobbs (1967) estimated 772 as a maximum colony sue for huntii Greene in southern Canada and over 3,000 bees per colony, based on data from Medler (1959), for huntii found in New Mexico. B. rnedius Cresson in Mexico may reach the same number (Michener and LaBerge, 1954). Dias (1958) reported a potential of 3,056 incarum Franklin from Brazil. Thus, it would appear that under optimum conditions several species from the western hemisphere have sufficient potential colony size for successful semi-domestication for crop pollination
A New Species of Podapolipid Mite, and a Redescription of Tetrapolipus Blattae (Oudemans) (Acarina: Podapolipidae)
A description of a new species of podapolipid mite, Tetrapolipus oudemansi, associated with the Philippine cockroach, Panesthia angustipennis (Illiger) is presented. Tetrapolipus blattae (Oudemans 19 11) collected from P. angustipennis from Java is redescribed
Mites of Moths and Butterflies, Asher Treat. Cornell University Press, 1975. $35.00.
(excerpt)
Don\u27t let the price tag frighten you. This is a book you will turn to again and again, in fact every time you pick up a moth or butterfly and wonder if it is one of those on which Asher Treat found mites. The quotation on the fly leaf gives an insight into the enthusiasm and curiosity, as well as the thoroughness of Asher Treat. Whether in the field, at home, or in a museum collection, the search for mites on insect hosts is an adventure as exciting as any treasure hunt. Every insect, looked at closely enough to reveal a mite, is an exotic island whose bays and coves may harbor a lurking pirate or the telltale traces of some hidden thief
A New Species of \u3ci\u3eEutarsopolipus\u3c/i\u3e (Acari: Podapolipidae) From \u3ci\u3eHarpalus Pennsylvanicus\u3c/i\u3e (Coleoptera: Carabidae) From East Lansing, Michigan
Eutarsopolipus fischeri n.sp. (Acari: Podapolipidae) is described from the carabid beetle, Harpalus pennsylvanicus (DeGeer) and compared with the other species in the pterostichi group of Eutarsopolipus. Keys to groups of Eutarsopolipus and to species in the pterostichi group are provided
