Chondrostereum Purpureum

The mitochondrial DNA (mtDNA) of Chondrostereum purpureum (Pers.:Fr.) Pouzar was extracted and purified, and the size ranged from 51.8 to 66.4 kb. One isolate each from British Columbia, Alberta, Finland, the Netherlands, and New Zealand were found to have identical BamHI mtDNA restriction patterns, resulting in a mitochondrial genome of 63.8 kb. An additional isolate from British Columbia and one from Switzerland had different banding patterns, however, resulting in mitochondrial genomes of 66.4 kb and 51.8 kb, respectively. A sequence-characterized amplified region (SCAR) assay, based on a polymerase chain reaction, was developed to rapidly screen a larger population of 84 isolates from North America, Europe, and New Zealand. Two SCARs, one encoding the NADH 4 gene (3 kb) and the second encoding the ATPase VI and cytochrome b genes (5.1 kb), were digested with 24 restriction enzymes. There were no polymorphisms in the NADH 4 containing SCAR, while a single polymorphism was detected by NsiI in the ATPase VI - cytochrome b containing SCAR. Two mitochondrial haplotypes that were distributed throughout the sample population were thus identified. The coancestry coefficient (<$Q7A0D00000010446D80BFFEFF88A524F5343905055B98C420120907B4DDA9ECB1F0>) for all subpopulations of the sample population was calculated to be 0.0353. The level of gene diversity in the mtDNA ofC. purpureum suggested that the chance introduction of novel mitochondrial genes following biological control applications of the fungus is relatively low.

Buddleja davidii is a perennial woody shrub that is highly invasive in many parts of the world including New Zealand This study was conducted to assess the potential for inundative biological control of this weed using Chondrostereum purpureum a wound invasive basidiomycete The fungus has been registered for woody weed control in Canada and the Netherlands and is present throughout New Zealand Mature B davidii shrubs planted at the Scion campus Rotorua were cut 30 cm from the ground and the cut surface of the stems was immediately inoculated with C purpureumcolonised malt extract agar (MEA) and sealed with Parafilm There were four replicate shrubs for each of three isolates and the control (inoculation with sterile MEA) One year following inoculation no fruiting bodies of C purpureum have been observed on the treated B davidii Although the inoculated stems appear dead most replicates have extensive epicormic shoot development and are forming coppices

The introduction of the eleven-spotted ladybird Coccinella undecimpunctata to New Zealand in 1874: the first use of a ladybird for biological control, or a spurious record created by cumulative misreporting?

Coccinella Undecimpunctata

The introduction of the eleven-spotted ladybird Coccinella undecimpunctata to New Zealand in 1874 has been widely quoted as the first importation of an insect for biological control in New Zealand and one of the first anywhere. However, searches of historical records show no evidence that such an introduction was made or attempted. Instead, there is clear evidence that the presently accepted record arose by a process of cumulative misreporting. An account of discussions in the Entomological Society of London in December 1873 about possible introductions of various beneficial insects to New Zealand was misreported by the American entomologist C. V. Riley, and several subsequent authors restated his version with further modifications and additions. This created the record of the introduction of C. undecimpunctata to New Zealand in 1874 that has been accepted and repeated ever since.

The biology of Rhyssa persuasoria, L., and of Ibalia leucospoides, Hochenw., has already been sketched in a preliminary paper published in this Bulletin (xix, pp. 67–77, pl. iii, 1928) in collaboration with Mr. R. N. Chrystal, of the Imperial Forestry Institute. The following observations were made by the writer chiefly at the Farnham House Laboratory, during the spring and summer of 1928, and are gathered together in view of his departure from England. The work of collecting and rearing supplies of Rhyssa and Ibalia for shipment to New Zealand, for the biological control of Sirex nodilio (juvencus), has been continued on a larger scale. The present notes were made incidentally during this work and are arranged under nearly the same headings as in the previous paper, to which they are supplementary. One error needs correcting. It was stated (on p. 75) that the larch (Larix europaea, D.C.) is indigenous, though actually planted in the Oxford locality mentioned. As a matter of fact, of course, larch, though Palaearctic, is not indigenous to Britain.

Crop Losses

New Zealand produces approximately 5,500 tonnes of brassica seed per year, two thirds of which, valued at $13M, is exported. Black rot caused by Xanthomonas campestris pv. campestris is a common disease of brassicas, and while crop losses are not extensive in New Zealand, internationally total crop losses have been reported. Seeds are the primary source of inoculum and the ease with which this inoculum spreads means that even small traces can cause severe epidemics. Genetic resistance to black rot is a complex trait which makes breeding for resistance in brassicas challenging. The effectiveness of chemical and cultural practices is variable. Biological control with natural antagonistic microbes may provide a more effective means of controlling black rot and other pests and diseases, and create opportunities for increasing the export value of brassica seed. Current cultural practices and the potential for biological control for the management of black rot are reviewed. Keywords: biocontrol, Brassicaceae, crucifer
