Distinguishing Character

AbstractThe shape of one single category of hemocytes served as a critically distinguishing character between larvae of two closely related species of Euxoa (Lepidoptera: Noctuidae) that were otherwise practically identical in external features. The ratio of length/width of fusiform plasmatocytes in heat-fixed blood films was significantly smaller in larvae of E. campestris (Grote) than in E. declarata (Walker).

Cortinarius alpinus as an example for morphological and phylogenetic species concepts in ectomycorrhizal fungiExtensive morphological and molecular analyses of closely related species from alpine, subalpine and montane habitats should enable a comparison of ecological, morphological and phylogenetic species concepts in ectomycorrhizal mushrooms. One fundamental question of this study was whether alpine species really exist, and which criteria, besides the specific habitat, could reliably be used for the de-limitation of such taxa. For this reason, 56 rDNA ITS sequences were generated or downloaded from GenBank for 10 closely related species of Cortinarius subgenus Myxacium, section Myxacium. Several collections were sequenced for each of the following taxa: Cortinarius absarokensis, C. alpinus, C. favrei, C. fennoscandicus, C. grallipes, C. mucosus, C. muscigenus, C. septentrionalis, C. trivialis and C. vernicosus. Moreover, spore statistics were carried out for 38 collections of alpine and subalpine taxa. These data provide clear evidence for C. favrei being a synonym of C. alpinus. C. absarokensis and C. alpinus can clearly be delimited based on pileus diameter and average dry weight per basidiome, even in overlapping habitats, but spore size and shape is not a good distinguishing character. Phylograms have very short branches, and base differences between ITS sequences are generally very low in this group, and give no resolution for the included taxa of this section. Based on these results, species concepts of ectomycorrhizal mushrooms are discussed in detail.

AbstractThe length of mature, fusiform plasmatocytes is a suitable character for distinguishing between last instar larvae of the closely related species Euxoa annir (Streck) and E. lutulenta (Smith). This is a consistent character for a number of Euxoa species, but unreliable in E. altera (McD) where it changed in constant fashion during this stage. The relationship between plasmatocyte length and the duration of aestivation was also examined and showed no clear correlation.

The strawberry cutworm, Amphipoea interoceanica (Smith), has recently become an important pest of strawberry plants in Manitoba (Ayre 1980) and Quebec (Mailloux and Bostanian 1985). Larvae damage or kill the plants and commercial plantings are sometimes heavily damaged. Strawberry cutworm is widely distributed in North America and is broadly sympatric with a morphologically similar species, Amphipoea americana (Speyer) (Forbes 1954), which is occasionally a pest of corn (Gibson 1920). Sex pheromones of these species have not been reported, although Roelofs and Comeau (1971) found that males of strawberry cutworm were attracted to (Z)-9-tetradecenyl acetate (abbrev. Z9- 14:Ac). A sex attractant for strawberry cutworm would provide a convenient method for monitoring population levels in the vicinity of strawberry fields.

Antennal Responses

AbstractThe three closely related species of Euxoa cutworm moths comprising the declarata group gave identical male antennal responses to synthetic C10 to C18 alkenyl derivatives. An extract and a solution of the volatile emissions from E. campestris females when fractionated by gas chromatography yielded a single EAG-active fraction whose elution corresponded to a C10 acetate. The active component was assigned (Z)-5-decenyl acetate based on its mass spectrum and capillary GC retention time and the EAG responses of campestris males to isomeric decenyl acetates. Field trials demonstrated (Z)-5-decenyl acetate attracted males of all three species although it was not as attractive as live females. Attraction was suppressed by (Z)-5-dodecenyl actate, (Z)-7-dodecenyl alcohol, and (Z)-7-dodecenyl acetate.

Four closely related species of Schinia are diagnosed using characters of maculation, genitalia, larval host plants, and distribution. The revised status of both Schinia albafascia Smith and Schinia brunnea Barnes and McDunnough are based on differences in wing maculation and male and female genitalic structures. The revised synonymy of Schinia megarena Smith with Schinia tertia (Grote) is discussed. Male and female genitalia are described and illustrated for the first time for all species.

Presents the results of a comparative morphological analysis of the variability of 9 quantitative and quali-tative characteristics of the leaf (length, width and index of the leaf, the number (or number of pairs) of leaf lobes, length, width and index of the lateral leaf lobe, the number of denticles along the edge of the leaf lobe, leaves in a sample with entire and toothed edges of the leaf blade) of closely related species Va-leriana officinalis L. and V. alternifolia (Bunge) Ledeb. Samples of 7 cenopopulations of V. officinalis (South Urals) and 5 cenopopulations of V. alternifolia (Central Yakutia) served as the material for the analysis. In both species, the levels of variability of morphological traits of the leaf are not lower than the average, predominantly increased, the least variable trait is the number of pairs of leaf lobes. In the sam-ple of V. alternifolia, the prevailing frequency of occurrence of leaves with a certain number of leaf lobes is not expressed; most values fall within a wide range from 11 to 17 pcs. (5-8 pairs) leaf lobes; in the sample of V. officinalis, there is a pronounced peak in the number of leaf lobes equal to 16 pcs. (8 pairs), most of the leaves fall in the range from 14 to 18 pcs. (7-9 pairs) leaf lobes. Valeriana alternifolia is characterized by relatively small leaves with 5-8 pairs of narrow lobes, mostly whole-edged. Valeriana officinalis is characterized by relatively large and elongated leaves with 7-9 pairs of relatively wide lobes with several denticles along the edge. To differentiate closely related species, the following quantitative morphological characteristics of a leaf can be reliably used: length, width and index, number of leaf lobes, length, width and leaf lobe index.
