Commodity Risk Assessment of Black Pine (Pinus Thunbergii Parl.) Bonsai from Japan
SCIENTIFIC OPINION ADOPTED: 28 March 2019 doi: 10.2903/j.efsa.2019.5667 Commodity risk assessment of black pine (Pinus thunbergii Parl.) bonsai from Japan EFSA Panel on Plant Health (EFSA PLH Panel), Claude Bragard, Katharina Dehnen-Schmutz, Francesco Di Serio, Paolo Gonthier, Marie-Agnes Jacques, Josep Anton Jaques Miret, Annemarie Fejer Justesen, Alan MacLeod, Christer Sven Magnusson, Panagiotis Milonas, Juan A Navas-Cortes, Stephen Parnell, Philippe Lucien Reignault, Hans-Hermann Thulke, Wopke Van der Werf, Antonio Vicent Civera, Jonathan Yuen, Lucia Zappala, Andrea Battisti, Anna Maria Vettraino, Renata Leuschner, Olaf Mosbach-Schulz, Maria Chiara Rosace and Roel Potting Abstract The EFSA Panel on Plant health was requested to deliver a scientific opinion on how far the existing requirements for the bonsai pine species subject to derogation in Commission Decision 2002/887/EC would cover all plant health risks from black pine (Pinus thunbergii Parl.) bonsai (the commodity defined in the EU legislation as naturally or artificially dwarfed plants) imported from Japan, taking into account the available scientific information, including the technical information provided by Japan. The relevance of an EU-regulated pest for this opinion was based on: (a) evidence of the presence of the pest in Japan; (b) evidence that P. thunbergii is a host of the pest and (c) evidence that the pest can be associated with the commodity. Sixteen pests that fulfilled all three criteria were selected for further evaluation. The relevance of other pests present in Japan (not regulated in the EU) for this opinion was based on (i) evidence of the absence of the pest in the EU; (ii) evidence that P. -
Is Light Pollution Driving Moth Population Declines? a Review of Causal Mechanisms Across the Life Cycle
Insect Conservation and Diversity (2020) doi: 10.1111/icad.12447 MAJOR REVIEW Is light pollution driving moth population declines? A review of causal mechanisms across the life cycle DOUGLAS H. BOYES,1,2,3 DARREN M. EVANS,2 RICHARD FOX,3 3 1 MARK S. PARSONS and MICHAEL J. O. POCOCK 1UK Centre for Ecology & Hydrology, Wallingford, UK, 2School of Natural and Environmental Sciences, Newcastle University, Newcastle upon Tyne, UK and 3Butterfly Conservation, Wareham, Dorset, UK Abstract. 1. The night-time environment is increasingly being lit, often by broad- spectrum lighting, and there is growing evidence that artificial light at night (ALAN) has consequences for ecosystems, potentially contributing to declines in insect populations. 2. Moths are species-rich, sensitive to ALAN, and have undergone declines in Europe, making them the ideal group for investigating the impacts of light pollution on nocturnal insects more broadly. Here, we take a life cycle approach to review the impacts of ALAN on moths, drawing on a range of disciplines including ecology, physiology, and applied entomology. 3. We find evidence of diverse impacts across most life stages and key behaviours. Many studies have examined flight-to-light behaviour in adults and our meta-analysis found that mercury vapour, metal halide, and compact fluorescent bulbs induce this more than LED and sodium lamps. However, we found that ALAN can also disrupt reproduction, larval development, and pupal diapause, with likely negative impacts on individual fitness, and that moths can be indirectly affected via hostplants and predators. These findings indicate that ALAN could also affect day-flying insects through impacts on earlier life stages. -

Visual Cues of Oviposition Sites and Spectral Sensitivity of Cydia Strobilella L
Journal of Insect Physiology 101 (2017) 161–168 Contents lists available at ScienceDirect Journal of Insect Physiology journal homepage: www.elsevier.com/locate/jinsphys Visual cues of oviposition sites and spectral sensitivity of Cydia strobilella L. MARK ⁎ Johan Jakobssona, , Miriam J. Henzea,b, Glenn P. Svenssona, Olle Lindc, Olle Anderbranta a Department of Biology, Lund University, Sweden b Brain Research Institute, University of Queensland, Australia c Department of Philosophy, Lund University, Sweden ABSTRACT We investigated whether the spruce seed moth (Cydia strobilella L., Tortricidae: Grapholitini), an important pest in seed orchards of Norway spruce (Picea abies (L.) Karst.), can make use of the spectral properties of its host when searching for flowers to oviposit on. Spectral measurements showed that the flowers, and the cones they develop into, differ from a background of P. abies needles by a higher reflectance of long wavelengths. These differences increase as the flowers develop into mature cones. Electroretinograms (ERGs) in combination with spectral adaptation suggest that C. strobilella has at least three spectral types of photoreceptor; an abundant green-sensitive receptor with maximal sensitivity at wavelength λmax = 526 nm, a blue-sensitive receptor with λmax = 436 nm, and an ultraviolet-sensitive receptor with λmax = 352 nm. Based on our spectral measurements and the receptor properties inferred from the ERGs, we calculated that open flowers, which are suitable ovi- position sites, provide detectable achromatic, but almost no chromatic contrasts to the background of needles. In field trials using traps of different spectral properties with or without a female sex pheromone lure, only pheromone-baited traps caught moths. -
Identification of Dioryctria
SYSTEMATICS Identification of Dioryctria (Lepidoptera: Pyralidae) in a Seed Orchard at Chico, California 1 2 3 1 AMANDA D. ROE, JOHN D. STEIN, NANCY E. GILLETTE, AND FELIX A. H. SPERLING Ann. Entomol. Soc. Am. 99(3): 433Ð448 (2006) ABSTRACT Species of Dioryctria Zeller (Lepidoptera: Pyralidae) are important pests of conifers, particularly in seed orchards, and accurate species identiÞcation is needed for effective monitoring and control. Variable forewing morphology and lack of species-speciÞc genitalic features hinder identiÞcation, prompting the search for additional diagnostic characters. Mitochondrial DNA (mtDNA) sequences from the cytochrome c oxidase I and II genes (COI and COII) were obtained from specimens collected at lights, pheromone traps, and host plants in the PaciÞc Northwest, focusing on a U.S. Forest Service seed orchard in Chico, CA. A 475-bp fragment of COI was used to identify eight distinct genetic lineages from 180 Dioryctria specimens, and these were identiÞed as eight described species. Comparisons among mtDNA variation, adult morphology, larval host association, and pheromone attraction were used to assign individuals to species groups and to identify diagnostic characters for species identiÞcation. A 2.3-kb fragment of COI-COII was sequenced for 14 specimens to increase resolution of phylogenetic relationships. Species groups were well resolved using both the 475-bp and “DNA barcode” subsets of the 2.3-kb sequences, with the 475-bp fragment generally showing lower divergences. The zimmermani and ponderosae species groups were sister groups and had similar male genitalic morphology and larval feeding habits. The pentictonella group was sister to the zimmermani ϩ ponderosae group clade, and all species have raised scales and a Pinus sp. -
Bat Aggregational Response to Pest Caterpillar Emergence Ján Blažek*, Adam Konečný & Tomáš Bartonička
www.nature.com/scientificreports OPEN Bat aggregational response to pest caterpillar emergence Ján Blažek*, Adam Konečný & Tomáš Bartonička Moths (Lepidoptera) are major agricultural and forest pests in many parts of the world, including Europe, with many causing great economic damage to crops, horticultural plants, stored items, and wool products. Here, we focus on two ecologically similar inchworms, Operophtera brumata and Erannis defoliaria, known for their high foliage consumption during the spring emergence of caterpillars. We hypothesise that bats could play a role in reducing pests such as caterpillars by switching to this abundant emerging prey. At two infested and one control forest sites, caterpillars were sampled during spring to determine levels of infestation. At the same time, bat fight activity was monitored during the peak in caterpillar abundance. During the spring caterpillar outbreak, we collected faecal samples of forest-dwelling bats capable of using gleaning. The majority of samples were positive for our focus species, being 51.85% for O. brumata and 29.63% for E. defoliaria faecal samples. The foraging activity of two gleaning bats, Myotis nattereri and Myotis bechsteinii, increased at both infested sites, but not at the control site, during caterpillar emergence, as did foraging of Plecotus auritus/austriacus, which used both gleaning and aerial hawking. We conclude that both specialists and occasional gleaners, which prefer diferent prey but are able to switch their foraging strategies, aggregate at sites during pest emergence and, as such, our results confrm the high potential of bats to reduce numbers of pest species such as caterpillars. A predator’s efect on prey populations is generally studied using numerical responses 1,2 driven by two mecha- nisms, migration of predators to sites with high prey concentrations (aggregational response) and predator reproduction, which results in a delayed increase in the density of predators3. -
