A controlled release granular carbosulfan pesticide was tested for efficacy against Hylastes ater damage of Pinus radiata seedlings in secondrotation forests in the central North Island Our study involved control seedlings and seedlings treated with 10 g or 15 g carbosulfan granules per seedling Seedling mortality ranged from 0 to 8 at the five sites When seedling mortality was high (8) mortality was reduced to 07 and 0 for carbosulfan granules applied at 10 g/seedling and 15 g/seedling respectively While seedling mortality in the five sites was low a large proportion of seedlings were damaged (38 to 83 of untreated seedlings) by H ater Untreated seedlings were damaged more frequently and with greater severity than treated seedlings The results indicate that that carbosulfan should protect P radiata seedlings from damage caused by H ater when used at the recommended field rate

Hylastes Ater

Many bark beetles (Coleoptera Curculionidae Scolytinae) exhibit a wide array of acoustic abilities including sounds used in mate attraction territoriality and defence In New Zealand the goldenhaired bark beetle Hylurgus ligniperda and the black pine bark beetle Hylastes ater are two species of forest insects which may be found on export logs Acoustic signals have been shown to discourage a related bark beetle the western pine beetle Dendroctonus from entering into pine logs and to disrupt mating and tunnelling These recent studies combined with observations of H ligniperda and H ater helped to establish the concept that acoustic disruption could be used as part of a wider systems approach to deter these beetle species near saw mills skid sites and ports If proven effective this technique would add value to New Zealand log exports and decrease the reliance on toxic fumigants as the primary control measure This study shows some of the functions and physical characteristics of the acoustic signals produced by H ligniperda and H ater

Different Origins

The golden-haired bark beetle, Hylurgus ligniperda (F.), is a common forest insect which may be associated with pine (Pinus radiata D.Don) logs exported from New Zealand. We tested the dose-mortality responses of H. ligniperda adults, from two different origins (field vs laboratory), to methyl bromide (MB), the most widely used fumigant worldwide; and to ethanedinitrile (EDN), a potential alternative to MB. Naked insects were fumigated with either MB or EDN at 10°C for 4 and 3 hours, respectively. Laboratory adults had been reared on artificial diet under controlled conditions for >10 generations. Field adults, by contrast, had been recently collected from Lindgren funnel traps with lures of alpha-pinene and ethanol. Tolerance to the two fumigants tested was significantly different, according to the origin of the insects, with field-collected adults being less tolerant to MB and EDN than laboratory-reared ones. The implications of our results for the development of disinfestation schedules for New Zealand export logs will be discussed.

Species Being

The seasonal flight of Hylurgus ligniperda (Fabr.) and Hylastes ater (Paykull) and the effect of log placement in Pinus radiata D. Don plantations on colonization by these species in Chile are described. Seasonal flight activity was monitored with α-pinene and ethanol-baited traps at three sites and colonization synchrony with trap logs. In two experiments with individual logs and log decks, data were recorded on adults found under the logs, attacks on the bark surface, and adults beneath the bark of logs in three storage treatments: individual logs and log decks (1) touching the soil; (2) elevated above the soil; and (3) touching other logs (individual logs) or logs separated with spacers (log decks). Each treatment was replicated in a plantation and a clearcut. At San José (region IX) and Peña Blanca (region VIII), H. ligniperda flew primarily in spring and H. ater flew in spring and fall. At Brasil (region VIII), H. ligniperda and H. ater flew primarily in summer through fall. The flight of H. ligniperda was more synchronized with colonization of logs than was that of H. ater. The mean number of attacks was significantly higher on individual logs and log decks stored on the soil than on those elevated above the soil, and significantly higher in the clearcut than in the plantation. Mean numbers of adults beneath the bark did not vary significantly among individual-log treatments, but were significantly lower in the log decks separated by spacers. Logging during nondispersal periods (June–August in regions VIII–X) and storing log decks above the soil could reduce beetle colonization of newly cut logs. With this information, management of recently cut logs (harvesting, transport, and storage operations) could be scheduled and executed so as to reduce the risk of these species being introduced into log-importing countries.

Pine (Pinus radiata D Don) logs exported from New Zealand must undergo fumigation to ensure they are free of phytosanitary insects to meet the requirements of importing countries The goldenhaired bark beetle Hylurgus ligniperda (F) is one of the major hitchhiker species that can infest New Zealand pine logs Adults and larvae can be present in the bark and cambium layer of freshly cut logs To examine ways of reducing rates of methyl bromide fumigation diet containing both life stages (extracted from pine logs) was exposed to 0 49 or 73 g/m3 methyl bromide for 16 h in 28litre fumigation chambers at 5 10 15 or 20C Both the 49 g/m3 and 73 g/m3 methyl bromide exposures resulted in 100 mortality at all temperatures Average mortality among controls was larvae 7 adults 23 The results indicate that the present methyl bromide fumigation rates used for pine logs exported from New Zealand could be reduced

Fungal Associates

Bark beetles (Coleoptera: Scolytinae) are known to be associated with fungi, especially species of Ophiostoma sensu lato and Ceratocystis . However, very little is known about these fungi in Spain. In this study, we examined the fungi associated with 13 bark beetle species and one weevil (Coleoptera: Entiminae) infesting Pinus radiata in the Basque Country of northern Spain. This study included an examination of 1323 bark beetles or their galleries in P. radiata. Isolations yielded a total of 920 cultures, which included 16 species of Ophiostoma sensu lato or their asexual states. These 16 species included 69 associations between fungi and bark beetles and weevils that have not previously been recorded. The most commonly encountered fungal associates of the bark beetles were Ophiostoma ips , Leptographium guttulatum , Ophiostoma stenoceras , and Ophiostoma piceae . In most cases, the niche of colonization had a significant effect on the abundance and composition of colonizing fungi. This confirms that resource overlap between species is reduced by partial spatial segregation. Interaction between niche and time seldom had a significant effect, which suggests that spatial colonization patterns are rarely flexible throughout timber degradation. The differences in common associates among the bark beetle species could be linked to the different niches that these beetles occupy.
