XI Content II Summary As a monophagous herbivorous species that is native to Asia, the Box tree pyralid Cydalima perspectalis Walker (Lepidoptera: Crambidae) is one of the accidentally introduced non-native species that successfully survived, reproduced and became established in Europe. The aesthetic damage and total loss of Buxus is not only limited to local plantings, but also extends widespread in urban areas as well as to the natural Buxus stands, which are already affected or remain highly endangered. The objective of this investigation was the implementation of an effective, eco- and user friendly method for regulating C. perspectalis and preserving unaffected Buxus plants, based on usable biocontrol agents as well as on an effective monitoring system. The occurrence of wild populations of C. perspectalis and seasonal moth flight activity was recorded by pheromone and light traps between 2012 and 2015 in Hessia (GER). Both trap systems were found to be suitable for monitoring C. perspectalis that is required to allow the proper timing of control measures. Two main flight periods were identified, which indicate the existence of two generations. Basic data on the sex ratio (on average 43% ± 10% females) and the appearance of the melanic phenotype (on average 14% ± 2.9%) were collected. The ability of eight parasitoid Trichogramma species to parasitize and locate C. perspectalis eggs was assessed in the laboratory. Despite all tested species examined and oviposited into exposed eggs, resulting parasitation rates were low and ranged between 4% and 20% for most of the species. Only T. dendrolimi parasitized significantly more eggs with rates above 40%. Potentially egg defensive mechanisms were suggested that may impede higher parasitization. Thus, no specialized Trichogramma species had been found yet for a practicable inundative release. The beneficials Chrysoperla carnea Stephens (Neuroptera: Chryspidae) and Orius majusculus Reuter (Heteroptera: Anthocoridae) preyed on C. perspectalis eggs in experimental studies on prey acceptance and prey location on Buxus plants. C. carnea preyed on average 89% offered eggs during the prey acceptance bioassay and 49% offered eggs during the prey location on the Buxus plant within 72 h. In contrast, O. majusculus preyed only 41% and 13%, respectively. Therefore, the conservation of natural enemies as O. majusculus and the inundative release of beneficials such as C. carnea can be considered as supporting tools in the biological control of C. perspectalis. Susceptibility of C. perspectalis to the prospective biological control agents Neem (NeemAzal®-T/S) and Entomopathogenic nematodes (Nemastar®) was assessed in laboratory bioassays and field trials. When NeemAzal®-T/S treated leaf discs were consumed by larvae, a significant effect on vitality and feeding activity was noted after 14 days of exposure (47%-62% Summary III mortality; 10% of larvae were still feeding). Larvae (2nd and 4th developmental stage) demonstrated high susceptibility to Nemastar® (50 EPN per larva caused 100% mortality after 7 days). Both agents were much less reliable in their efficacy in field trials in comparison to the constant effectiveness of Bacillus thuringiensis. Their use is only possible in smaller areas, if individual feeding damage will be observed and proper surveillance will be considered. Potential repellent and toxic properties of 13 plant oils and extracts on egg deposition of C. perspectalis female moths and larval mortality were investigated in the greenhouse and the laboratory. When Thymus vulgaris L. and Malaleuca alternifolia M. & B. treated leaf discs were offered to larvae, a significant effect on feeding deterrence, survival and larval weight was noted. T. vulgaris was the most effective oil considering repellent and toxic effects. Its effective lethal concentration (LC50) was determined to be 1% (v/v) at 72 h. None of the tested control options alone provide an opportunity for the effective, eco- and user friendly regulation of C. perspectalis. The application of products based on B. thuringiensis is still the only highly effective and available biological control method but new approaches

It was first detected in 2011 in Istanbul. It is a native pest of box plants in Asia. Its first discovery in Europe has been made in 2007 in Germany. Since then it has been successfully established in various ecosystems in Europe. Caterpillars feed on box leaves and cause severe defoliation and tree deaths. In this study, damage level and defoliation percentage were investigated on ornamental and naturally growing box plants. Area of study: Box plants were sampled in Artvin in the Eastern Black Sea Region of Turkey. Material and Method: A total of 90 box plants that were either naturally growing or ornamental box plants were sampled Main results: Majority of the naturally growing box plants (63.4%) had strong and very strong damages, and 71.4% of the ornamental box plants had middle and strong damage levels. Research highlights: Of the all observed plants, 53.4% had 40-100% defoliation and 25% of these plants did not recover.
  • Pest Alert: Box Tree Moth (Cydalima Perspectalis)

    Pest Alert: Box Tree Moth (Cydalima Perspectalis)

    Pest Alert Box Tree Moth (Cydalima perspectalis) The box tree moth is an invasive pest that primarily feeds on boxwood species (Buxus spp). In its native range, it also feeds on burning bush (Euonymus alatus), Japanese spindletree (E. japonicus), purple holly (Ilex chinensis), and orange jessamine (Murraya paniculate) once boxwood in the vicinity are completely defoliated. Distribution and Spread The box tree moth is native to temperate and subtropical regions in Asia. It was first reported in Europe in 2007, after which it spread rapidly across European countries and into Western Asia and Northern Africa. In 2018, it was documented in Canada. The rate of spread for the box tree moth has varied since its introduction in Europe, with some cases peaking at 96 miles per year. Long distance movement of the box tree moth across Europe occurred primarily through the movement of infested Adult moths (top and bottom left), damage (bottom) boxwood plantings. Box tree moths are highly mobile and used for edging, as hedges, thick brown border spanning 1.6 and are good fliers. Natural spread and/or clipped into different shapes to 1.8 inches. Some adults have of this moth in Europe is about 3 to make topiaries. The box tree completely brown wings with a small to 6 miles per year. One analysis moth can cause heavy defoliation of white streak on each forewing. Males from Europe concluded that natural boxwood plants if populations are left and females show both colorations. dispersal from continental Europe unchecked. Defoliation of existing to the United Kingdom was possible, and new growth can kill the plant.

E-mail of corresponding author: [email protected] Introduction Biological invasion by alien species is a great ecological and economical threat, with a multitude of negative impacts on human and animal health, local biodiversity (flora and fauna) and cultural landscape (Hulme & Roy, 2010). The box tree moth Cydalima perspectalis (Walker, 1859) (Lepidoptera: Crambidae) is an invasive species on box tree Buxus spp. in Europe, which has been spreading and establishing across the continent during the last decade. The pest was included in the alert list of the European Plant Protection Organisation (EPPO) in 2007 but was removed in 2011 (Strachinis et al., 2015). The box tree moth Cydalima perspectalis (Walker, 1859) is known from the humid subtropical regions of East Asia, India (Hampson, 1896), China (Walker, 1859), Japan (Inoue, 1982), Korea (Park, 2008), and Far East Russia (Kirpichnikova, 2005). The larvae feed on the leaves of Buxus microphylla Siebold &Zucc., but also accept other Buxus species (Maruyama, 1993). In 2006, the box tree moth was registered in southwestern Germany (Krüger, 2008). In 2007, it was also found in Switzerland (Billen, 2007) and

(Diptera Tachinidae). The factitious host Galleria mellonella (L.) (Lepidoptera Pyralidae) was maintained as con- trol. In the bioassay, C. perspectalis and G. mellonella mature larvae were separately exposed for 3 hours to E. larvarum mated females. Box tree moth larvae were accepted by E. larvarum females, but a lower number of eggs were laid on them than on G. mellonella. Most eggs hatched, as also shown in the anatomical and histological studies, but no puparia formed in any accepted C. perspectalis larva. Two out of six first instar E. larvarum larvae penetrated the body of a box tree moth larva and were encap- sulated. The encapsulation response turned into the formation of the respiratory funnel by two parasitoid larvae, similarly to what happens in G. mellonella. The results obtained in this study showed that the exotic species was unsuitable as host for E. larvarum. The mortality following the parasitoid larval activity (independently of successful parasitization) was, however, not significantly different between C. perspectalis and G. mellonella. The overall results suggest that the mortality of C.

    Entomopathogenic fungi as a biological control for the Greater melon fly Dacus frontalis (Becker) (Diptera: Tephritidae) Esam Omar Elghadi A thesis presented for the degree of Doctor of Philosophy School of Biology Faculty of Science, Agricultural and Engineering Newcastle University United Kingdom June-2016 i ii Abstract The Greater melon fly Dacus frontalis is one of the most economically damaging pests of cucurbit fruits in Africa. The aim of this study was to evaluate entomopathogenic fungi for use against D. frontalis and develop better strategies in using these biological agents for integrated fly management. Laboratory experiments were conducted to evaluate the pathogenicity of some commercial biopesticides based on several strains of entomopathogenic fungi against different life stages of the fly. Met52 Granular biopesticide (MET52) based on Metarhizium anisopliae caused the greatest pathogenicity to the adults. Therefore, MET52 was selected for further investigation. Pupal age and an increasing rate of MET52 had no effect on pupal mortality. However, post- emergence mortality increased when the fungus was applied on young pupae. Prior application of MET52 in a granule form caused considerable mortality to larval-pupal stages compared with a drench application. A sublethal effect of MET52 infection, reducing adult reproduction, was found. The fungus was more effective when applied as a granule in soil against emerging adults than as a direct spray against adults. MET52 fungus was able to persist in soil, reducing the adult emergence and subsequent fly population for more than two months after a single application, and also inducing new infections among the fly population. Percentage mortality of untreated females mating with inoculated males was greater than that of untreated males mating with inoculated females.

In 2013, larvae of the moth caused lethal damage to artificial plantations of boxwood in the Greater Sochi area and Novorossiysk area in southern Russia. In summer and autumn 2015, 48 and 13 boxwood study sites respectively in the natural Buxus colchica (Pojark) forests were examined in six regions (out of nine) in the Republic of Georgia. The substantial damage caused by C. perspectalis feeding on boxwood leaves in native boxwood forests was discovered in four different regions in the western part of the Republic of Georgia: Imereti, Samegrelo-Zemo Svaneti, Guria and Autonomous Republic of Adjara. Today, the box tree moth is known to occur at several locations in the Black Sea coastal region of the Caucasus Mountains. This paper provides the first well documented record of C.

    Turkish Journal of Forestry | Türkiye Ormancılık Dergisi 2016, 17(Special Issue): 71-75 | Research article (Araştırma makalesi) Cedar forests under threat of new pests Mohamed Mounaa, Mustafa Avcıb,* Abtract: During our studies on the insects of cedars - including field observations, sampling and rearing - we have often identified known or new pests on the tree. At the same time, we have noticed the sporadic presence of other insects, which feed only on cedar but cause insignificant damage. We have nevertheless noticed that these insects can cause outbreaks that harm the tree. In addition, we have noted the sudden apparition on cedar of unknown insects, or species living on other trees that currently constitute a threat to the cedar forest. In this chapter, those new cedar pests and their threats, both in natural forests and in artificial ones in Western and Eastern Mediterranean, are presented. Their symptoms on cedar and the possible causes of their outbreaks are considered. In order to know the potential pests in advance, an inventory of all the insects living on cedar is provided. Because of the complexity of the phenomenon of the emergence of new pests on cedar, we propose to combine efforts in the Mediterranean basin, in a tighter coordination between researchers interested in these trees.
