Agrilus planipennis (Coleoptera: Buprestidae) is a devastating invasive pest of ash trees. This wood-boring insect is native to Asia and established in European Russia about 20 years ago. It severely damages Fraxinus pennsylvanica plantations and quickly spreads. In 2019 we first detected A. planipennis in Ukraine. More than 20 larvae were collected from under the bark of F. pennsylvanica trees on 5 September 2019 in the Markivka District of the Luhansk Region. The coordinates of the localities of collection were 49.614991 N, 39.559743 E; 49.614160 N, 39.572402 E; and 49.597043 N, 39.561811 E. The photos of the damaged trees with larval galleries, exit holes and larvae are presented. It indicates that A. planipennis is established in the east of Ukraine. This fact is important for development of quarantine protocols to prevent or at least slow the further spread of this invasive pest in Europe.

A novel anamorphic yeast species is described to accommodate three isolates recovered from the guts of three different wood-boring insect larvae collected in Henan, central China. On the basis of sequence analyses of the D1/D2 domains of the large-subunit rRNA gene and the internal transcribed spacer regions, the three strains are assigned to a novel species of the genus Wickerhamomyces, although the formation of ascospores was not observed. These strains also exhibited a number of distinct morphological and physiological characteristics that clearly differentiated them from Wickerhamomyces mucosus, Candida odintsovae and Wickerhamomyces rabaulensis, the most closely related species. In view of the phenotypic differences and unique rRNA gene sequences, we consider that these three isolates represent a novel species of the genus Wickerhamomyces, Wickerhamomyces mori sp. nov. The type strain is NYNU 1216T ( = CICC 1983T  = CBS 12678T).

The respiratory gas exchange and the function of the spiracles in all stadia of Orthosoma brunneum are investigated. CO2 is released discontinuously from the prepupae, pupae, resting adults, and molting larvae while the animals are in atmospheric air. The spiracular valve of the prepupae and pupae flutters irregularly within a small amplitude in air. At intervals corresponding to the CO2 bursts the flutter amplitude increases. Intubation of one to two spiracles stops both CO2 bursts and the wide opening of the spiracles. In 4% ambient O2 or in 14% CO2 the spiracles open widely and the CO2 bursts are eliminated. Apparently, in this insect, inhabiting a moist environment, the spiracular control of external respiration is as highly developed as in free-living insects.

AbstractHormesis induced by insecticides at the dosage lower than what ostensibly directly causes death on insects was studied. This paper reports the effects of the in vivo application of varied concentrations of chlorpyrifos (CPF) on Plutella xylostella (DBM). The insecticide concentrations applied included 0.000025–2.5 mg l−1, which are far lower than LC1 (7.2 mg l−1), for the CPF-susceptable (Si) DBM, and 250 mg l−1 which is far below LC1 (1286 mg l−1), for the CPF-resistant (Rc) DBM, as well as LC10- and LC50-doses for both strains. Significant hormesis was found with the ‘hermetic-CPFs’, i.e., 0.0025 mg l−1 for Si DBM and 2.5 mg l−1 for Rc DBM, at the normal or high temperature either in a 24 h or under a long-term treatment. These doses of CPF significantly stimulated the development and increased the fecundity of Si and Rc DBM at 25°C with approximately 23.5–29.8% activity increase on acetylcholinesterase (AChE) and 30.5–91.3% increase on glutathione S-transferases (GSTs) at 25 or 38°C in 4–24 h. The enzymatic activities were significantly reduced by LC50-CPF at 25°C in vivo, but the inhibition was relieved significantly, if the insects were first subjected to a hormetic-CPF pretreatment. It was remarkable that the average rates of enzymatic activity increase were 67.5–76.6% for AChE and 366–546% for GSTs. Consequently, it was concluded that the hormesis on Si and Rc DBM could be induced by CPF doses far below LC1 at normal or high temperature in short- or long-term treatment. These findings might help to improve the current insect control practices in the field.

Insect Attack

The problem of wood-boring insect attacks is gaining greater interest in Italy today. Wood-boring insects (Coleoptera, termites) often cause both structural and aesthetic damage on wooden structures which can sometimes give rise to human health concerns. Possible causes of current insect infestations include the use of timber originating from plantations, as well as bad post-felling practices such as late harvesting and stocking in unsuitable places before final processing. In the past, these insects were not thought to pose an economic threat to timber in service in Italy, but, in recent years, they have become a problem. The aim of this paper is to report on case studies concerning the occurrence of these unusual wood-boring insects on timber in service and, on the basis of the Authors experience, to formulate an in situ inspection protocol. The species we are dealing with in the case studies are: Bostrichus capucinus, family Bostrichidae, associated with Lyctus spp. (Fam. Lyctidae) and Lymexylon navale, family Lymexylonidae, belonging to the group of the so-called ambrosia beetles or pinhole borers. All these species were found on hardwoods, where they had bored into the sapwood except for L. navale which was also able to bore into heartwood, causing major concerns about its potential danger to timber in service. A technical integrated approach in evaluating insect attacks on on-site timber elements is also described here. The assessment is based on different methods, i.e. visual inspection and acoustic detection. This procedure is proposed as a basis for the development of an intervention protocol in the early stages of infestation.

Agrilus planipennis is a devastating invasive pest of ash trees. This wood-boring insect native to Asia and established in European Russia about 20 years ago poses a serious threat to ash trees all over Europe. In 2019 we first detected Agrilus planipennis in Ukraine. More than 20 larvae have been collected from under the bark of Fraxinus pennsylvanica trees on 5 September 2019 in Markivka District of Luhansk Region. Coordinates of the localities of collection: 49.614991 N, 39.559743 E; 49.614160 N, 39.572402 E and 49.597043 N, 39.561811 E. The photos of damaged trees with larval galleries, exit holes and larvae are presented. There is no doubt that the pest is established in Ukraine. This fact is important for development of quarantine protocols to prevent or at least slow the further spread of this invasive pest in Europe.
