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.

A New Species

Summary A new species of Aporcelaimellus, collected in a watermelon field in Nigeria, is described, including its morphological and molecular (D2-D3 28S-rDNA, 18r-DNA) characterisation. Aporcelaimellus nigeriensis sp. n. is distinguishable by its 2.76-3.55 mm length, very coarse ventral body pores, lip region offset by deep constriction and 24-27 μm broad odontostyle 30-36 μm long at its dorsal and 28-31 μm at its ventral side, neck 648-779 μm long, pharyngeal expansion occupying 54-60% of total neck length, uterus 300-473 μm or 2.1-3.2 body diam. long and tripartite, V = 49-54, tail short and convex conoid (27-41 μm, c = 72-115, c′ = 0.5-0.7), spicules 108-137 μm long, and 9-10 spaced ventromedian supplements with hiatus. LSU analysis revealed a close relationship of A. nigeriensis sp. n. with other Aporcelaimellus species and questioned, once more, the monophyly of Aporcelaimidae. SSU phylogenetic tree was not able to resolve the relationship between the new species and other closely related species.

The Relationship

The ability to recognize oneself in a mirror is known as self-recognition, whereas delayed self-recognition is the ability to recognize the relationship between current self and past actions. While 3-year-old human children have self-recognition without the ability for delayed self-recognition, 4-year-old human children demonstrate the capability for both. Chimpanzees, the most closely related species to humans, have displayed the ability for delayed self-recognition. However, little is known about whether this ability is shared among all hominid species. In this study, we examined whether orangutans, the most distantly related species to humans within the hominid group, could recognize their own past actions using the preferential-looking paradigm. Our results demonstrated that orangutans were able to discriminate between a delayed video of themselves presented after a 2-s delay and a recorded video of the day prior. This suggests that orangutans have the ability to relate their own past actions to current actions, although we found no evidence of self-directed behaviour. We believe these findings will contribute to our growing understanding of hominid self-recognition.

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.

AbstractSamples were taken weekly from 11 June to 1 October 1968 from brown slime fluxes occurring on trees (mostly elms) in Rockport, Mass., and in central and eastern areas of Connecticut and held in the laboratory for the emergence of adult insects.The most common emergents were Aulacigaster leucopeza (Meigen) and its parasite, Aphaereta colei Marsh, Mycetobia divergens (Walker), and Dasyhelea oppressa Thomsen. The only drosophilid reared from brown slime flux was Drosophila robusta Sturtevant, a species that was not particularly common.A comparison of the brown flux fauna of Great Britain with that of New England shows that some cosmopolitan species occur in flux in both countries. Species whose distribution is limited to only one of the countries are represented in the other country by closely related species (ecological homologues).The relationship between climatological factors and the fluxing condition of trees is discussed. The factor considered most important in continuing the fluxing state is rainfall during the late summer months.

Phylogenetic relationships among species of Bulbophyllum sect. Trias and related taxa in Bulbophyllum has not been previously studied due to scarcity of appropriate samples. In this study, we aimed to assess the relationship of these taxa and investigate interspecific relationships of these orchids using DNA sequences from two plastid genes, rbcL and matK, and one nuclear region, nuclear ribosomal internal transcribed spacer, nrITS. Our results showed that all Bulbophyllum sect. Trias species were embedded among other groups of Bulbophyllum, supporting the already published transfer of Trias to synonymy of Bulbophyllum. All trees revealed that the Indochinese sect. Trias form a monophyletic group that could be divided into three groups coincident with their vegetative characters. This study further shows that nrITS sequences can be sufficient for inferring phylogenetic relationship among Trias species, although this marker and the combination of this plus the plastid genes are not able to distinguish the differences between some closely related species.

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.

Structural Differences

Genome size varies across the tree of life, with no clear correlation to organismal complexity or coding sequence, but with differences in non-coding regions. Phylogenetic methods have recently been incorporated to further disentangle this enigma, yet most of these studies have focused on widely diverged species. Few have compared patterns of genome size change in closely related species with known structural differences in the genome. As a consequence, the relationship between genome size and differences in chromosome number or inter-sexual differences attributed to XY systems are largely unstudied. We hypothesize that structural differences associated with chromosome number and X-Y chromosome differentiation, should result in differing rates and patterns of genome size change. In this study, we utilize the subgenera within the Drosophila to ask if patterns and rates of genome size change differ between closely related species with differences in chromosome numbers and states of the XY system. Genome sizes for males and females of 152 species are used to answer these questions (with 92 newly added or updated estimates). While we find no relationship between chromosome number and genome size or chromosome number and inter-sexual differences in genome size, we find evidence for differing patterns of genome size change between the subgenera, and increasing rates of change throughout time. Estimated shifts in rates of change in sex differences in genome size occur more often in Sophophora and correspond to known neo-sex events.

AbstractThe turnover of the radioisotope 137Cs is shown to be of a one-component nature and to be positively correlated with temperature for males of both Glossina morsitans Westw. and G. pallidipes Aust. A direct correlation with oxygen consumption is also demonstrated, and the relation for both species may be described by the same regression line. The feasibility of using 137Cs as a metabolic label for tsetse is therefore confirmed, and it is suggested that the predictive nature of the relationship between radioisotope turnover and metabolism may extend beyond closely related species.
