In July 2000, tree decline was observed in a commercial pecan (Carya illinoensis (Wang.) K. Koch) orchard in Crisp County, GA. Most affected trees exhibited dead branches in the upper canopy, stunted growth, and feeder roots with small galls and associated egg masses typical of root-knot nematode infection. All declining trees that were examined had root systems infected with a Meloidogyne sp. Efforts to culture the nematode on tomato (Lycopersicon esculentum Mill. ‘Rutgers’) were unsuccessful. Identification of the nematode was determined by two laboratory procedures in March 2001. Female nematodes were teased from fresh pecan root galls of declining trees in Georgia, and identified by determining the esterase phenotype from replicate samples of single females compared with standard root-knot nematode species, including a population of M. partityla (3). Galled roots also were sent to New Mexico State University in Las Cruces, where mitochondrial DNA from specimens was extracted and compared with that from standard root-knot nematode species and known populations of M. partityla (2). Specimens had esterase phenotypes and DNA patterns consistent with M. partityla. Esterase phentoypes were inconsistent with M. incognita and M. arenaria, and DNA patterns were inconsistent with M. incognita, M. javanica, and M. hapla. Specimens at both locations were identified as M. partityla Kleynhans (1). To our knowledge, this is the first report of M. partityla from Georgia and the third report of this nematode outside of South Africa. The first and second report of M. partityla from pecan in the United States occurred in Texas and New Mexico in 1996 and 2001, respectively (3,4). Our inability to culture the M. partityla-GA isolate on tomato substantiates previous experience with this nematode in the United States (3) and is not surprising, since this species has a host range limited to the Juglandaceae. Furthermore, M. partityla may be endemic to North America and not South Africa. It is believed this nematode entered South Africa on pecan seedling roots imported from the United States between 1912 and 1940 (1). The unusually narrow host range may explain why M. partityla has gone unrecognized for so long in the United States compared with the more common Meloidogyne spp. (i.e., M. incognita and M. arenaria) with wider host ranges found in pecan orchards. Determining the distribution of M. partityla within the major pecan-growing regions of Georgia and throughout North America is warranted. References: (1) K. P. N. Kleynhans.

The first record of the occurrence in North America of the white-tipped clover case-moth, Coleophora frischella L., was made in June 1966 when a single adult was taken by Heinemann on Picton Island, N.Y., in the St. Lawrence River (Freeman, personal communication). Independently, Trieselmann collected the larvae from white sweet-clover, Melilotus alba Desr., on 28 July through to 8 August 1966 at many points around Pembroke, Ont. Detailed examinations made at two of the collection points indicated that between 15 and 20% of sweetclover seeds were damaged. Because of its potential economic significance, the authors wish to make the presence of this species known to agricultural entomologists in Canada and the United States.

Degree Of Maturity

Previous experimental and field studies have shown that variations within the genus Haematoloechus may result from differences in age and degree of maturity, extent of crowding, species of host, and other factors.Based on these observations, only 6 of the 15 previously known species from Canada and the United States are considered valid. The valid species and their synonyms are as follows: Haematoloechus longiplexus Stafford, 1902; H. breviplexus Stafford, 1902; H. varioplexus Stafford, 1902 (= H. parviplexus, = H. buttensis, = H. similiplexus, = H. floedae, and H. uniplexus); H. kernensis Ingles, 1932 (= H. tumidus); H. medioplexus Stafford, 1902; and H. complexus (Seely, 1906) (= H. coloradensis, = H. confusus, = H. oxyorchis).The existence of three species groups is hypothesized. Haematoloechus longiplexus and H. breviplexus constitute one group, characterized by little geographical variation and a narrow host range. They are typically parasites of Rana catesbeiana and R. clamitans. Haematoloechus varioplexus and H. kernensis constitute the second group. These species have a wider host range and greater variation in characters purported to be specific differences. The third group includes those lung flukes which do not contain extracaecal loops (H. medioplexus and H. complexus). Of these, only H. medioplexus had little geographical variation and was found to occur in a single frog host.

Field symptoms, host distribution, pathogen morphology, and phylogenetic analyses clearly demonstrated that the rust fungus infecting alder buckthorn in Connecticut is Puccinia coronata var. coronata sensu stricto. To our knowledge, this is the first report and confirmation of P. coronata var. coronata s.s. in the United States. Additional collections from purported aecial and telial hosts of P. coronata var. coronata s.s. are necessary to determine its host range, geographic distribution, and incidence within the United States and elsewhere in North America.

Sandia Cave is located in an escarpment of Pennsylvania limestone in Ellis Canyon, thirty miles northeast of Albuquerque, New Mexico. It presents an interesting problem in regard to the time when man existed in North America contemporaneously with the horse (equus?), the ground sloth (nothrotherium), and other extinct Pleistocene forms. In the United States, discoveries of artifacts with extinct mammals do not show necessarily that man existed in the Pleistocene or ice age, but may indicate that the mammals have survived that period and become extinct in more recent times. The best criteria for dating would be collections made in the glaciated areas and associated with glacial deposits. However, this is not always possible, and other means must be sought. Dating can be done to some degree of accuracy by the interpretation of climatic conditions that existed at the time the deposits were laid down.

Background: Pityriasis rotunda is a rare cutaneous disorder characterized by scaly, circular, well-demarcated, hypo- or hyperpigmented, fine plaques over the trunk and extremities. Objective: We present a case of pityriasis rotunda in a 44-year-old African-Canadian woman who presented to a community dermatology practice in Toronto. Results: Pityriasis rotunda has been well described in Japan, Italy, and South Africa. It is extremely rare in North America, with nine reported cases to date, the majority of which were diagnosed in the United States. Conclusion: Pityriasis rotunda is a rare cutaneous disorder associated with systemic disease. To the best of our knowledge, this is the second report of pityriasis rotunda diagnosed in Canada.

Four clones of the pea aphid, Acyrthosiphon pisum (Harris), collected from different regions in North America (St-Jean and Ile-aux-Coudres, Quebec, in Canada, and New Mexico and Kansas in the United States) were reared on an aseptic chemically defined diet and characterized into biotypes. The clones from St-Jean and Kansas appeared similar and represent one biotype, whereas those from New Mexico and Ile-aux-Coudres were different from each other, as well as from St-Jean and Kansas. Third-generation larvae were produced only by biotypes St-Jean and New Mexico; however, none of them reached the adult stage.The amount of diet ingested and its utilization by different clones also varied. In 24 h, the total diet ingested by flrst-instar larvae from St-Jean, Kansas, New Mexico, and Ile-aux-Coudres was 164,140, 112, and 65 μg per aphid respectively. During the same period the larvae increased their weights by 28, 13, 10, and 10% respectively. Total, or percent increase in weight, was however not proportional to the amount of diet ingested, thus reflecting on the relative efficiency of diet utilization by different clones.

The Past

The pine wood nematode, Bursaphelenchusxylophilus (Steiner and Buhrer) Nickle, causes a wilt of pines in Japan. Severe damage to forests in Japan have been occurring for the past 30 years. Recently, the nematode has been found on conifers throughout the United States. Little is known of the biology and etiology of the pine wood nematode in North America. At present, there appears to be little threat to native coniferous forests of the United States and Canada. This is indicated by the wide host range and extensive geographic distribution of the nematode, association of the nematode on trees severely weakened by insects and diseases, and presence of the nematode in the United States since the early part of this century. Monoculture of susceptible conifers, offsite plantings and the introduction of potentially more effective vectors could, however, result in an increased damage by the nematode.

The tribe Stenochiini Kirby, 1837 comprises six genera in North America with most species occurring in the tropical and temperateregions of the continent. Only two species in the genus Strongylium Kirby, 1818 have previously been reported from west of theContinental Divide in the United States from Arizona and New Mexico and no members of the tribe have been reported from the stateof Sonora, Mexico. We here report Strongylium tenuicolle (Say, 1826), known to be widely distributed east of the Rocky Mountains,from west of the Continental Divide for the first time from both Arizona and New Mexico. We similarly report the first records ofboth Strongylium apache Triplehorn and Spilman, 1973 and Strongylium atrum Champion, 1888 from Sonora. Oploptera chamelensis(Doyen, 1990) was previously known only from the type series from Jalisco, Mexico and is here reported from Sonora, which thereby extends the known range of this genus significantly. To promote consistency in generic recognition, we propose the transfer of Oploptera simplicicollis (LeConte, 1878) New Combination from Strongylium for the species distributed across the southeastern United States. Species diagnoses are given, and generic boundaries are discussed along with the expected diversity of the Sonoran Desert region.

Common Groundsel

Common groundsel (Senecio vulgaris, Asteraceae) is native to Europe and is now a common weed mainly in disturbed habitats of almost worldwide distribution. In November 2000, groundsel plants growing adjacent to lettuce fields in California's coastal Salinas Valley (Monterey County) showed symptoms of rust. In a 0.2-ha survey area, 75% of the plants were infected. Examination of weeds growing in four residential blocks also uncovered infected groundsel. Densely clustered, orange aecia were observed on leaves and stems. Stems were swollen where aecia had formed. Blossom and fruit formation was not notably reduced, although some involucral bracts were infected. Aeciospores measured 14 to 18 μm × 12.5 to 15 μm (fresh material). Telia were not found. The pathogen was identified as Puccinia lagenophorae Cooke, a rust fungus that is native to Australia and New Zealand and infects plants of the subfamily Asteroideae (family Asteraceae) (3). P. lagenophorae is an autoecious species forming only repeating aecia (stage I) and telia (stage III). There are six other rusts of Senecio that occur in the United States (1) that readily form aecia but not telia on Senecio spp. When only aecia are observed on Senecio, which is typical for P. lagenophorae (2), the following features can be used to differentiate it from these other species: no pycnia (stage 0) are formed; aecia are formed repeatedly; systemic growth that results in deformation of the host, including formation of galls with dense clusters of aecia on the stem; poorly developed aecial peridium; and aeciospores small, measuring 12.5 to 18.5 μm × 10.0 to 16.0 μm (4). In addition, P. lagenophorae forms aecia even at the end of the year in northern temperate zones, whereas heteroecious species form aecia only in spring and early summer (2). This is the first record of P. lagenophorae in North America. Specimens were deposited in the Arthur Herbarium, Purdue University. Outside its native habitat, this fungus has been found in Europe, Africa, the Middle East, and South America. There are about 60 known host species of P. lagenophorae (3) including ornamentals such as Bellis perennis, Calendula officinalis, and Senecio cruentus. The pathogen may have been introduced to North America via land from South America through Central America, or by the importation of ornamentals that were either infected with rust or infested with diseased groundsel.
