Key Parameter Comparisons Of Fungal Induced Mortality In Alfalfa Weevil Larvae (Coleoptera: Curculionidae), Robert J. Barney, Edward J. Armbrust

The Great Lakes Entomologist

Key parameters of alfalfa weevil larval mortality by Entornophthora phytonorni were compared weekly in three alfalfa fields. Rainfall appeared to be the overriding factor in seasonal larval infection rates.

Two Entomophthora Species Associated With Disease Epizootics Of The Alfalfa Weevil, Hypera Postica (Coleoptera: Curculionidae), In Ontario, D. G. Harcourt, J. C. Guppy, D. M. Macleod, D. Tyrrell

The Great Lakes Entomologist

Recent studies have shown that disease epizootics in Ontario populations of the alfalfa weevil, Hypera postica (Gyllenhal), are caused by a complex of two fungi.

Differences In Emergence Date And Size Between The Sexes Of Malacosoma Americanum The Eastern Tent Caterpillar (Lepidoptera: Lasiocampidae), Donald N. Bieman, J. A. Witter

The Great Lakes Entomologist

Malacosoma americanum males were smaller and began to pupate earlier than females. Since the sexes spent the same amount of time as pupae, males also emerged earlier. The adaptive significance of these results is discussed. Emergence data revealed an interesting sidelight; no moths emerged from cocoons inside tents.

Hawthorn Lace Bug (Hemiptera: Tingidae), First Record Of Injury To Roses, With A Review Of Host Plants, A. G. Wheeler Jr

The Great Lakes Entomologist

Hawthorn lace bug, Coryrhucha cydoniae (Fitch), is reported for the first time as damag- ing roses. Injury to climbing and hybrid Tea roses is described, and a list of known host plants is provided based on observations in Pennsylvania and review of literature. Preferred hosts are native and cultivated species of Amelanchier and Craraegus and ornamental Cotoneasrer and Pyracanrha. Damage to crabapple. fruit trees, mountain ash. and other rosaceous plants may occur when they are grown near more favored hosts.

Fourlined Plant Bug (Hemiptera: Miridae), A Reappraisal: Life History, Host Plants, And Plant Response To Feeding, A. G. Wheeler Jr, Gary L. Miller

The Great Lakes Entomologist

Phenology of the fourlined plant bug, Poecilocapsus lineatus, is presented for southcen- tral Pennsylvania; life history and habits are re-examined. Although breeding was previously thought to occur only on woody plants, we found that nymphs develop on numerous herbs. An extensive list of hosts, more than 250 species in 57 families, is compiled from the literature and the authors' observations; preferences are noted for plants in the Labiatae, Solanaceae, and Compositae. Damage consists of lesions on foliage, the size and shape of the spots varying with leaf texture, pubescence, and venation. Plant response to feeding is immediately visible, the lesions …

Description Of A New Nearctic Species Of Tragosoma Audinet-Serville (Coleoptera: Cerambycidae: Prioninae), With Species Validations, New Synonymies And A Lectotype Designation, Serge Laplante

Insecta Mundi

Tragosoma soror (Coleoptera: Cerambycidae: Prioninae), a new Nearctic species, is described and compared to its North American congeners. Tragosoma harrisii LeConte, revised status, and Tragosoma spiculum Casey, revised status are both resurrected from synonymy and considered valid species distinct from T. depsarium (Linnaeus). The Mexican T. nigripenne Bates is confirmed as a valid species. Tragosoma chiricahuae Linsley, new synonym, is placed in synonymy under T. spiculum Casey, and T. sodale Casey, new synonym, T. parvicolle Casey, new synonym, and T. repens Casey new synonym are placed in synonymy under T. harrisii. Tragosoma repens is …

Social Parasitism Among Ants At The E.S. George Reserve In Southern Michigan, Mary Talbot

The Great Lakes Entomologist

(excerpt)

A mode of life in which one species spends all or part of its existence in close contact with, and at the expense of, another species is rather common among ants. Sudd (1%7) stated that about one sixth of all known European species are parasitic to some extent. At the Edwin S. George Reserve in Livingston County, Michigan, 28.7% (25 of the 87 species) fall into the category of forms considered to be in some way parasitic on other ants.

Persistence Of Jack Pine Budworm Choristoneura Pinus Pinus, (Lepidoptera: Tortricidae) Egg Mass Chorions On Jack Pine Foliage, Harold O. Batzer, Daniel T. Jennings

The Great Lakes Entomologist

More than one-fifth of old and nearly one-half of new jack pine budworm egg mass chorions remained on the foliage after one year, and an experienced observer could not determine accurately the age of one-fourth of them. Counts of new egg masses are used to estimate current populations, and large errors could result.

Effects Of Various Photoperiods On Color And Pubescence In Thyanta Pallidovirens Accerra (Hemiptera: Pentatomidae), J. E. Mcpherson

The Great Lakes Entomologist

The effects of a range of developmental photoperiods on adult dimorphism in Thyanta pallidovirens accerra were studied under laboratory conditions. Adults reared in photo- phases of 14L and higher had short pubescence and those in 12L and lower, long pu- bescence. No dimorphism in color was produced in these same photophases.

Effects Of Continuous And Split Developmental Photophases During Each 24 Hour Period On Adult Morphology In Euschistus Tristigmus Tristigmus (Hemiptera: Pentatomidae), J. E. Mcpherson

The Great Lakes Entomologist

Rearing immatures of Euschistus tristigmus tristigmus in 8L:16D, 8L: 4D:8L;4D, and 16L:8D showed that the length of each photophase, rather than an accumulated total of shorter photophases, during each 24 hr period was the determining factor in producing adult dimorphism in shoulder shape and number of midventral abdominal spots.

Evaluation Of Two Systems Used To Extract Alfalfa Weevil Larvae (Coleoptera: Curculionidae) From Alfalfa Samples, S. J. Roberts, D. P. Bartell, E. J. Armbrust

The Great Lakes Entomologist

A modified Berlese funnel system was developed to extract alfalfa weevil larvae (Hypera postica) from quadrats 30.5 cm on a side. Data from this system were comp.wed with simultaneous data from a hand sorting extraction system. In most instances, the modified Berlese system was as efficient as the hand sorting method and the number of man hours required to process samples by hand was far greater than that required by the Berlese system.

Effect On Constant Versus Fluctuating Temperature Regimes On Bathyplectes Curculionis (Hymenoptera: Ichneumonidae) Activity, Robert J. Barney, E. J. Armbrust, R. D. Pausch, S. J. Roberts

The Great Lakes Entomologist

Individual female Bathyplectes curculionis parasites were exposed to either a series of constant or fluctuating temperature regimes and supplied with a new group of host Hypera postica larvae every day. The fluctuating temperatures were calculated from an average of weekly air temperatures during a period of actual field oviposition by the parasite. The rearing of adult parasites under a constant versus fluctuating temperature regime resulted in no significant difference in parasitism, longevity, or fecundity. The threshold for B. curculionis activity was estimated to be 6-8°C.

Biology Of The Hyperparasitic Wasp Perilampus Similis (Hymenoptera: Perilampidae), Foster Forbes Purrington

The Great Lakes Entomologist

Planidia of the hyperparasitic wasp, Perilarnpris similis Crawford, enter their braconid host, Agathis rnetzneriae Muesebeck, during that host's active growth phase, returning to the outer surface when the host is prepupal. Second instar perilampids search for and destroy conspecific larvae on the surface of the braconid prepupae, thus eliminating super- parasitism. Planidia in primary hosts, Metzneria lappella Zeller moth larvae in burdock seeds, unparasitized by the braconid persist without further development through pupation and occur in various tissues of the adult moth.
