Hemlock Looper

AbstractThree species of Telenomus Haliday are egg parasitoids of the hemlock looper, Lambdina fiscellaria (Guenée), in Canada. Telenomus coloradensis Crawford and Telenomus droozi Muesebeck are redescribed and Telenomus flavotibiaesp.nov. is described and illustrated from material collected in Quebec. Telenomus coloradensis was found to be the predominant egg parasite, followed by T. droozi. Telenomus flavotibiae was found to be an uncommon parasite of hemlock looper eggs. All three species are recorded from Newfoundland to British Columbia. Keys to species of Telenomus associated with the hemlock looper, including two closely related species previously confused in the literature, are also given.

Host Plant Specificity

Bryobia praetiosa Koch (1836) was formerly regarded as a complex of closely related species or races similar in morphological characters but varying widely in life-history, host plant specificity, and habits. The authors (30) have recently shown that two species, the clover mite, B. praetiosa Koch, and the brown mite, B. arborea Morgan and Anderson, can be distinguished in British Columbia on the basis of morphological characters. This paper presents ecological data in support of the morphological evidence.

A New Species

Since Summers described Bryobia curiosa in 1953 from an unknown host in the Mojave Desert, California, this unusual mite with the stylophore cleft mediodistally has never been reported elsewhere. In 1959, two new, closely related species were discovered: one was found at Summerland, British Columbia, and is described herein; the other was taken in California. I am indebted to Dr. F. M. Summers, University of California, Davis, Calif., for the loan of specimens of B. curiosa and for permitting me to examine specimens of his undescribed species from California.

Christmas Trees

Incidence of damage to needles of Douglas fir, Pseudotsuga menziesii (Mirb.) Franco, by larvae of gall midges has been noted in British Columbia since 1935. In 1953 severe midge damage to Douglas fir occurred in sections of British Columbia, Washington, Idaho and Montana. Outside of brief and general reference to these gall midges in literature and in unpublished notes, almost nothing was known of their biology, and the species remained undescribed. Relatively little interest has been shown these insects until recent years, when severe infestations in southeastern British Columbia affected the sale of Douglas fir for use as Christmas trees.

The problem of species concepts and delimitation in the heteroecious rusts is discussed. It is illustrated by Puccinia karelica, which is known in typical form from Europe, southern Alaska, coastal British Columbia, and apparently Kamchatka and Saghalien. A distinct population in eastern Canada and adjacent United States is named ssp. laurentina ssp. nov. P. karelica is compared with closely related species and its probable mode of evolution is discussed.

Genome Amplification

Finger millet is a superior staple food for human beings. Microsatellite or Simple Sequence Repeat (SSR) marker is a powerful tool for genetic mapping, diversity analysis and plant breeding. In finger millet, microsatellites show a higher level of polymorphism than other molecular marker systems. The identification and development of microsatellite markers are extremely expensive and time-consuming. Only less than 50% of SSR markers have been developed from microsatellite sequences for finger millet. Therefore, it is important to transfer SSR markers developed for related species/genus to finger millet. Cross-genome transferability is the easiest and cheapest method to develop SSR markers. Many comparative mapping studies using microsatellite markers clearly revealed the presence of synteny within the genomes of closely related species/ genus. Sufficient homology exists among several crop plant genomes in the sequences flanking the SSR loci. Thus, the SSR markers are beneficial to amplify the target regions in the finger millet genome. Many SSR markers were used for the analysis of cross-genome amplification in various plants such as Setaria italica, Pennisetum glaucum, Oryza sativa, Triticum aestivum, Zea mays and Hordeum vulgare. However, there is very little information available about cross-genome amplification of these markers in finger millet. The only limited report is available for the utilization of cross-genome amplified microsatellite markers in genetic analysis, gene mapping and other applications in finger millet. This review highlights the importance and implication of microsatellite markers such as genomic SSR (gSSR) and Expressed Sequence Tag (EST)-SSR in cross-genome analysis in finger millet. Nowadays, crop improvement has been one of the major priority areas of research in agriculture. The genome assisted breeding and genetic engineering plays a very crucial role in enhancing crop productivity. The rapid advance in molecular marker technology is helpful for crop improvement. Therefore, this review will be very helpful to the researchers for understanding the importance and implication of SSR markers in closely related species.
