The purpose of this study is to develop a technique for quantifying the adult dispersal and retention patterns of two clearwing moths, Glossosphecia romanovi and Sesia yezoensis (Sesiidae). We ...analyzed concentrations of 20 elements in each individual body by ICP-MS and discriminated their natal sites from the data. We found that element concentrations in the bodies of clearwing moths differed for each natal site to some extent and we could discriminate their natal site by the data. In particular, in the case of G. romanovi, we could generally discriminate small plots of their natal sites and detect an individual which had immigrated from another environment. This method can be used for other insects.
Na de ontdekking van een populatie van de zwartkophoornaarvlinder Eusphecia melanocephala in Belgisch Limburg, vlakbij de Nederlandse grens, werden in 2018 ook enkele typische sporen van deze ...wespvlindersoort gevonden in Nederland. Een uitgebreider onderzoek in 2019 resulteerde in de vondst van een volwassen rups die werd opgekweekt tot imago. Deze wespvlindersoort maakt dus ook deel uit van de Nederlandse fauna, maar het bekende areaal lijkt momenteel beperkt tot het zuiden van de provincie Limburg.
A group of clearwing moths Sesiidae (Syn.: Aegeriidae) is analyzed here with special emphasis on genetics of currant clearwing moth (Synanthedon tipuliformis, CLERCK 1759). DNA sequences of the ...longest (1544 nt) available sequence of Sesiidae genes Co1 (cytochrome oxidase subunit-1 of mitochondrial DNA, mtDNA) (mtDNA; NCBI# AJ864359.1) were analyzed after In silico data mining, and dendrogram was edited to reveal molecular diversity and genetic distances among Sesiidae species. Batesian mimicry, sexual dimorphism, and genetics and genomics of Sesiidae are indicated.
In the present paper the Chinese Sesiidae species described by Zukowsky from the Mell collection are reviewed. The following new combinations are introduced: Glossosphecia melli (Zukowsky, 1929) ...comb. n., Nokona semidiaphana (Zukowsky, 1929) comb. n., and Adixoa leucocyanea (Zukowsky, 1929) comb. n. Aegeria sangaica Zukowsky, 1932 is formally established as a synonym of Toleria abiaeformis Walker, 1865. Additional Sesiidae records published by Zukowsky (1929) from China are critically analyzed and mostly rejected as the specimens on which these records were based were found to be misidentified. Melittia inouei (Arita & Yata, 1987) and Macroscelesia japona (Hampson, 1919) are new records for the fauna of China.
In juni 2020 werden bij een onderzoek in Zuid-Limburg van Maastricht tot Vaals op een locatie in Eijsden-Margraten drie exemplaren van de oranjetip-eikenwespvlinder Synanthedon conopiformis in een ...trechterval met het soortspecifieke feromoon gevangen. In 2021 en 2022 werd de soort ook ontdekt op negen locaties in Noord-Limburg en op een locatie in Zuid-Gelderland.
We evaluated a combination of noninsecticidal alternatives to control trunk-damaging dogwood borer, Synanthedon scitula (Harris), consisting of novel barrier technologies, used alone or in ...combination with mating disruption. Barrier formulations evaluated included fibrous barriers of nonwoven ethylene vinyl acetate (EVA) and nonfibrous barriers of rubberized paint (elastomer) used in building coatings. To examine efficacy of dogwood borer control in orchards, all barrier trials were replicated in field tests, both in combination with mating disruption and without it. Trunk inspections to determine whether mating disruption and barriers effectively reduced actual tree infestation showed pheromone disruption significantly reduced infestation compared with the untreated check, but was not as effective as trunk handgun sprays of chlorpyrifos. EVA trunk barriers were effective in preventing borer infestation compared with untreated trees. The elastomer did not differ from the check or the EVA treatment. There was no interaction between disruption and barrier treatments. Barrier field life and durability was assessed over 2 yr by comparing degradation over time due to weathering and other environmental effects including animal damage. The EVA persisted and remained more intact than the elastomer, but was in need of reapplication after 2 yr. Barriers were also screened for efficacy against voles in small-plot trials in nonorchard locations with known high vole pressure; they were tested either alone, combined with a repellent (thiram), or, in the case of the elastomer only, combined with an abrasive (sand). Only the EVA significantly lowered vole chewing damage relative to the untreated checks.
Larval grape root borer, Vitacea polistiformis (Harris) (Lepidoptera: Sesiidae), feed on roots of wild Vitis and commercially important Vitis species and rootstocks in portions of the eastern United ...States. Grape root borer pupal exuviae sampling in Virginia vineyards from 2008 to 2012 revealed that infestation levels varied substantially among 48 vineyard blocks. Data on horticultural (cultivar, rootstock, vine age, and planting area), cultural (insecticide use, ground cover,weedcontrol, and irrigation), and environmental variables (proximity to forest, soil composition, soil moisture holding capacity, pH, organic matter, bulk density, and cation exchange capacity) from each block were subjected to optimal quantification using categorical principal component analysis (CATPCA). Variables with component loading values greater than or equal to 0.70 from the CATPCA were used as predictors and pupal exuviae density as the dependent variable in binary logistic regression. A prediction model was developed by including statistically significant variables in the logistic regression. CATPCA showed that seven vineyard factors (ground cover, soil texture, soil mass moisture, soil pH, clay/sand ratio, clay/silt ratio, and sand/silt ratio) based on three selected principal components were significant for subsequent regression analysis. Binary logistic regression showed that soil mass moisture and clay/sand ratio were statistically significant factors contributing to differences in infestation among vineyard blocks. Based on these two factors, a risk prediction model for calculating the probability of grape root borer infestation in vineyards was developed and validated using receiver operating characteristic curve. Results are discussed in relation to the practical implications of a predictive, risk assessment model for grape root borer management.
Lepidopteran larvae damage to the branches of cultivated kiwifruit is a serious problem in the southwest part of Ehime Prefecture, Japan. We reared these larvae using seedlings of kiwifruit, and ...found that this species was a clearwing moth, Nokona feralis(Leech). After emergence, the 1st instar larvae bored into the current shoots from the base of the petiole, and almost all of the leaves near the positions where the larvae bored were withered. Larvae moved to 30–40 mm diameter branches and bored into them, and expelled a large amount of frass from the site the larvae attacked. The puparia were observed mainly on 20–50 mm diameter branches. One to five eggs were laid, mainly on the petiole base. Ovipositions by females were observed until the middle of October. Eggs overwintered and then larvae hatched the next April. The hatching rate was 30.4% and 39.2% of eggs were attacked by a parasitoid wasp. Males were captured by pheromone traps from early September to the middle of October, and a peak of male capture was observed from late September to early October. Of 28 pheromone traps placed across Ehime Prefecture, only 4 traps in the southwest region(Ainan Town, Uwajima City, and Yawatahama City)captured males. To suppress larval attack, some insecticides were carried out in the season of larval hatch. Cypermethrin, methidathion(DMTP), and cartap effectively prevented the larval attack to kiwifruit.
