(anamorph Botryozyma cognata), was isolated from beetle galleries in Idaho, USA. A. cognata was found on the surface of free-living nematodes, Panagrellus dubius, collected from galleries created by the long-horned beetle Saperda calcarata in Populus (aspen), and the weevil Cryptorhynchus lapathi in Salix (willow). A. cognata isolates were collected from similar habits and in relatively close proximity to those of A. americana, the only species described from North America. The recognition of A. cognata as a distinct species was supported by morphological and molecular data. Thallus cells of A. cognata were significantly shorter than those of A. americana. Low DNA reassociation values, notably different randomly amplified polymorphic DNA (RAPD), inter-sequence simple repeat (ISSR), and amplified fragment-length polymorphic (AFLP) fingerprints, and sequence divergence in both the D1/D2 domain of the nuc-LSU rDNA and an additional unidentified region were all consistent with the recognition of a new species.

SP - 1 EP - 18 KW - Cryptorhynchus lapathi AB - Fifty-six taxa in forty-two genera are reported from wood-boring beetle activity of the long-horned beetle Saperda calcarata (poplar borer) (Coleoptera: Cerambycidae) and weevil Cryptorhynchus lapathi (poplar and willow borer) (Coleoptera: Curculionidae) during a study designed to assess the distribution of the yeast genus Ascobotryozyma. Regular collections from wounds, frass, galleries, and larvae in Populus tremuloides (trembling aspen) over 27 months revealed trends in fungal species composition in relation to gallery location and age of beetle damage. In Salix, fungi were identified only from galleries from which Ascobotryozyma was found; thirty-four taxa are reported. Fungi identified in this study are compared with those from other surveys and their roles within the trees and associations with other organisms are discussed.

Usually not indigenous but commercial EPNs are used from northern European producers. Application of EPNs in forest biotopes is uncommon and only experimental trials have been conducted on few forest pests. It is important to consider that during the past 10 years, the occurrence of EPNs (Rhabditidae: Steinernematidae and Heterorhabditidae) was investigated in pine and oak woods in Southern Italy. Six percent of pine woods and 15.5% of oak woods were positive for the presence of nematodes. Steinernema feltiae was the most common (42%) species in both pine and oak woods. S. feltiae, S. apuliae and Heterorhabditis bacteriophora were collected in the pine woods and S. feltiae and S. affine in the oak woods. Many of the following indigenous EPNs isolated from forest soils were used in laboratory and field trials to control some dangerous insect pests of forest and urban trees in the Apulia region: Thaumetopoea pityocampa (Lepidoptera: Thaumetopoeidae), Corythucha ciliata (Rhynchota: Tingidae), Galerucella luteola (Coleoptera: Chrysomelidae) and Tomicus piniperda (Coleoptera: Scolytidae). Indigenous EPNs were also used against Balaninus (= Curculio) elephas (Coleoptera: Curculionidae) in Sicily and the Lazio region, whereas indigenous and commercial strains of EPNs were used to control Cephalcia arvensis (Hymenoptera: Pamphilidae), Zeuzera pyrina (Lepidoptera: Cossidae), Cossus cossus (Lepidoptera: Cossidae), Parenthrene tabaniformis (Lepidoptera: Sesiidae) and Cryptorhynchus lapathi (Coleoptera: Curculionidae) in the northern regions of Italy.

A1 - Gries, Regine SP - 1606 EP - 1613 KW - Cryptorhynchus lapathi AB - Hybrid poplar clones show varying levels of attack by Cryptorhynchus lapathi (L.), a wood-boring weevil. We studied differences in olfactory and feeding behavior among four different hybrid poplars in a series of laboratory bioassays. Weevils did not discriminate between resistant and susceptible clones base() on olfaction in pitfall bioassays or antennal responses but did discriminate against the most resistant hybrid, NM 6 (P. nigra L. X P. maximowiczii Henry), in choice and no-choice paired-twig feeding bioassays. In addition, the susceptible hybrid, TN 302-9 (P. trichocarpa Torrey and Gray X P. nigra), was preferred for feeding over Salix scouleriana Barratt ex Hooker, a preferred host in the wild. We conclude that resistance among hybrid poplars is in part based on antixenotic cues before oviposition.

A1 - Borden, John H. A1 - Gries, Regine SP - 357 EP - 366 KW - Cryptorhynchus lapathi AB - In British Columbia, native willows (Salix spp.) (Salicaceae) and, to a lesser extent, black cottonwood (Populus trichocarpa Torr. & Gray) (Salicaceae) are frequently attacked by the poplar and willow borer, Cryptorhynchus lapathi (L.) (Coleoptera: Curculionidae). Red alder (Alnus rubra Bong.) (Betulaceae), trembling aspen (Populus tremuloides Michx.), and bigleaf maple (Acer macrophyllum Pursh) (Aceraceae) are not attacked. We studied olfaction and feeding preferences in the laboratory and feeding, oviposition, and emergence in the field. Female C. lapathi preferred Scouler's willow (Salix scouleriana Barratt ex Hook.) over all other species by olfaction, but males did not discriminate between Scouler's willow and black cottonwood or trembling aspen. All species elicited at least some attraction in no-choice situations. Willow was generally preferred for feeding, but black cottonwood and red alder were also acceptable, unlike trembling aspen or bigleaf maple. In field caging experiments, adult weevils emerged from willow, black cottonwood, and red alder. We conclude that olfaction and feeding preferences are sufficiently powerful to mediate the frequent attack observed on native willows, the intermediate levels of attack on cottonwood, and the absence of attack on red alder. Successful development on red alder suggests that C. lapathi could expand its host range to include this species.

A1 - Borden, John H. A1 - Humble, Leland M. SP - 119 EP - 130 KW - Cryptorhynchus lapathi AB - The poplar and willow borer, Cryptorhynchus lapathi (L.), known to be present in British Columbia since 1923, primarily attacks species of Salix L. (Salicaceae) and Populus L. (Salicaceae). Larvae bore into stems, causing them to break easily. The impact of the weevil has been rising in recent years because of the increasing importance of poplar and willow from both economic and ecological perspectives. We conducted a study at 45 locations in British Columbia to determine host use among native Salix spp. and the between- and within-tree dynamics of C. lapathi. There were 11 new host records, but the incidence of attack was similar among species. Attacked trees were larger in general and had more dead wood and stems, more adventitious branches per stem, more total breaks per stem, and more naturally caused breaks per stem than their attack-free neighbours. Breaks caused by C. lapathi tended to be slightly larger in diameter and lower on the stem than naturally caused breaks. Bases of stems were preferentially attacked, and C. lapathi selected large stems in which to oviposit. As large attack-free trees become less abundant, weevils apparently start to attack small-diameter stems. Although C. lapathi is adversely affecting the health of willows in British Columbia, there is no evidence that any Salix species is threatened by weevil-caused extinction.

A1 - Borden, John H. SP - 2254 EP - 2259 KW - Cryptorhynchus lapathi AB - Damage caused by the poplar-and-willow borer, Cryptorhynchus lapathi (L.) (Coleoptera: Curculionidae), is reported to vary among hybrid poplar clones. We evaluated oviposition preferences and larval success in four hybrid poplars on potted and field-planted trees. Oviposition occurred somewhat less frequently and abundantly on two clones with Populus maximowiczii Henry parentage in field-planted and potted trees, and significantly fewer larvae survived to adulthood on those clones. No adults emerged from field-planted NM 6 (Populus nigra L. X P. maximowiczii) and four emerged from TM 256-28 (Populus trichocarpa Torrey & Gray X P. maximowiczii) on which male-female pairs of C. lapathi had been caged. In contrast, 50 and 140 adults emerged over the same 2-yr period from two susceptible clones (n = 20), TD 52-226 (P. trichocarpa X Populus deltoides Bartram ex Marshall) and TN 302-9 (P. trichocarpa X P. nigra), respectively. Thus, resistance expressed by clones with P. maximowiczii parentage partially involves decreased levels of oviposition, but more significantly, antibiosis in resistant clones prevents the development of larvae, probably in early spring.
