Technologies, Plainfield, IL) that were located in orchards and downloaded once per week. At each orchard, samples were collected weekly from 10 sampling sites. To avoid defruiting or defoliating trees with our destructive sampling method, each sampling site consisted of four trees sampled in a 4-week rotation. Sampling from a single tree per week was done to reduce sample collection time, which was considerable in abandoned orchards due to large tree size and difficult sampling conditions. Beginning in late April (full bloom-petal fall) and continuing weekly until October, ten fruit clusters from both the upper and lower half of one tree per sample site were removed and returned to the laboratory, where leaves and fruit were examined for eggs under lighted magnifying lenses. Several parameters were recorded when an egg was detected on a fruit cluster; including species determination (oriental fruit moth or codling moth), stage of development (fresh, hatched or parasitized), substrate (leaf or fruit), and position on leaf (top or bottom) or fruit (stem, side or calyx). When fresh eggs were found, they were excised from the substrate, surface disinfected in a 0.0628% NaOCl solution for five s, placed in a 30 ml plastic cup containing 10 ml of lima bean diet

Mating disruption for control of the Oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera:Tortricidae), in North Carolina apple orchards.

Mating disruption for control of the Oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera:Tortricidae), in North Carolina apple orchards.

The Oriental fruit moth (OFM), Grapholita molesta (Busck), is a major pest of stone and pome fruits in North America (Allen and Plasket 1958). Although OFM has long been an important pest of peaches, only recently has it become a key tortricid pest of apples in the Mid-Atlantic region (Walgenbach et al. 1999, Hull et al. 2001, Usmani and Shearer 2001). In North Carolina (NC), OFM completes at least four generations per season, with adult flight lasting from late March through October, a minimum time period of 150 days (J. Walgenbach, unpublished data). OFM larvae feed in the apple, usually at the calyx end and often do not feed on seeds (Chapman and Lienk, 1971).

The efficacy of novel diamide insecticides in Grapholita molesta suppression and their residues in peach fruits

The efficacy of novel diamide insecticides in Grapholita molesta suppression and their residues in peach fruits

The oriental fruit moth, Grapholita molesta (Busck, 1916) represents one of the most significant and de- structive pests of peaches in Serbia and worldwide. It is regularly found in peach and quince orchards in Serbia and it requires constant monitoring and use of protective measures (Stamenković 2005). Damage is caused by larvae that feed by boring into the grow- ing shoots or the fruits. Besides these types of direct damage, the indirect damage caused by G. molesta is also very significant. Fruit infestations reduce its quality and, thus, create economic losses, as well as increasing costs for sorting. Also, it can limit the

glomeruli process mixture-related information in specific ways indicates that odor processing inside the ALs of oriental fruit moth females is not uniform. Further, it suggests that interactions across these two glomeruli, and perhaps other glomeruli not yet identified, and between local and projection neurons might take place in the ALs prior to final odor processing and integration in higher-order brain centers (e.g. mushroom bodies). Experimental evidence of AL neuronal circuitry and synaptic interactions in the AL has been already provided for other insect species, including moths (e.g. Christensen et al., 1989; Christensen et al., 1993; Vickers et al., 1998) and locusts (e.g. Geffen et al., 2009; Bazhenov et al., 2005; Laurent et al., 2001). Response properties rather than spatial position seem to determine connectivity between glomeruli (Linster et al., 2005; Reisenman et al., 2008), and local AL circuitry seems to play an important role in shaping projection neuron responses in Drosophila sp. (Olsen and Wilson, 2008; Olsen et al., 2007; Silbering and Galizia, 2007; Silbering and Galizia, 2008). Because BOR and BES glomeruli have overlapping odor response profiles despite being spatially distant, it is likely that they are interconnected via local interneurons and that the activity in the BOR glomerulus contributes to the response profile of the BES glomerulus, and vice versa. It would be interesting to further investigate (a) network effects inside the ALs of the moths to test for interconnectivity between the BOR and BES glomeruli, and (b) the type of information conveyed by projection neurons into higher-order brain centers.

EFFECT OF WATER STRESS ON MOTH BEAN [ VIGNA ACONITIFOLIA(JACQ.) MARECHAL] GENOTYPES

EFFECT OF WATER STRESS ON MOTH BEAN [ VIGNA ACONITIFOLIA(JACQ.) MARECHAL] GENOTYPES

The study revealed that in general late flowering genotypes were more susceptible to drought than early flowering genotypes. However, Maru moth, a late flowering genotype, reflected more drought tolerance than early flowering CZM-99. Additionally, CZM-99 and CAZRI-Moth-1 were more susceptible to drought in their respective groups, at either stages of growth. These genotypes also invariably reflected less favourable plant water status and more metabolic derangements in terms of photosynthetic rate, nitrate reductase activity, chlorophyll loss, starch hydrolysis, proteolysis and associated accumulation of reducing sugars and free amino acids. Furthermore, moth bean genotypes were more sensitive to water stress at flowering as compared to stress at vegetative stage.

Evaluation of wet cupping therapy for persistent non specific low back pain: a randomised, waiting list controlled, open label, parallel group pilot trial

Evaluation of wet cupping therapy for persistent non specific low back pain: a randomised, waiting list controlled, open label, parallel group pilot trial

Methods: We recruited 32 participants (21 in the wet-cupping group and 11 in the waiting-list group) who had been having PNSLBP for at least 3 months. The participants were recruited at the clinical research centre of the Korea Institute of Oriental Medicine, Korea. Eligible participants were randomly allocated to wet-cupping and waiting-list groups. Following the practice of traditional Korean medicine, the treatment group was provided with wet-cupping treatment at two acupuncture points among the BL23, BL24 and BL25 6 times within 2 weeks. Usual care, including providing brochures for exercise, general advice for PNSLBP and acetaminophen, was allowed in both groups. Separate assessors participated in the outcome assessment. We used the 0 to100 numerical rating scale (NRS) for pain, the McGill Pain Questionnaire for pain intensity (PPI) and the Oswestry Disability Questionnaire (ODQ), and we assessed acetaminophen use and safety issues.

Antimicrobial peptide gene BdPho responds to peptidoglycan infection and mating stimulation in oriental fruit fly, Bactrocera dorsalis (Hendel)

Antimicrobial peptide gene BdPho responds to peptidoglycan infection and mating stimulation in oriental fruit fly, Bactrocera dorsalis (Hendel)

Phormicins belong to defensin family, which are important antimicrobial peptides (AMPs) in insects. These AMPs are inducible upon challenging by immune triggers. In the present study, we identified the cDNA of a phormicin gene (BdPho) in the oriental fruit fly, Bactrocera dorsalis (Hendel), a ruinous agricultural pest causing great economic losses to fruits and vegetables. The cDNA of BdPho contains a 282 bp open reading frame encoding 93 amino acid residues, and the predicted molecular weight and isoelectric point of BdPho peptide were 9.83 kDa and 7.54, respectively. Quantitative real‑time PCR analyses showed that the transcription level of BdPho was the highest in adult during different developmental stages and was the highest in abdomen among adult tagmata. Moreover, BdPho was highly expressed in fat body among different tissues, both in female and male adult. The mRNA level of BdPho was signifi‑ cantly up‑regulated to 7.46‑ and 14.53‑fold at 3 and 6 h after the insects were challenged with peptidoglycans from Escherichia coli (PGN‑EB), respectively, suggesting its antimicrobial activity against Gram‑negative microorganisms. Furthermore, the expression level of BdPho was significantly up‑regulated to 3.83‑fold after mating, suggesting that female adults might enhance their immunity by up‑regulating the expression level of BdPho during mating. These results firstly describe the basic properties of the phormicin gene from B. dorsalis, and lay the foundation for investi‑ gating functional properties of AMPs and exploring the molecular mechanisms in the immune system.

Modelling of the spread of a potential invasive pest, the Siberian moth (Dendrolimus sibiricus) in Europe

Modelling of the spread of a potential invasive pest, the Siberian moth (Dendrolimus sibiricus) in Europe

The aim of this study was to construct a grid-based spread model to predict the regions that are likely to be the most susceptible to the SM in Europe (excluding Russia). The spread of the pest from the access points was predicted from the climatic suitability of different localities to the SM, flight capacity of the moth, and the geographical distribution of suitable host trees. We fo- cused on relatively immediate threats to Europe, the next 20 years only. The effect of climate change on the spread of the SM was incorporated in the model, which is important in longer-term simulations. The model was used to calculate a probability map for the spread of the SM on the assumption that it enters the non-Russian parts of Europe in infected wooden materials imported through border stations between Russia and other European countries.

The secret service – analysis of the available knowledge on moths as pollinators in New Zealand

The secret service – analysis of the available knowledge on moths as pollinators in New Zealand

Abstract: On a global-scale, moths (Lepidoptera) are considered to be important pollinators for many plant families. However, the assumption that moths are also involved in pollination in New Zealand is underpinned by relatively little research. Here we review the evidence for moth pollination of flowering plants in New Zealand and compare the quality of evidence available with that of the global literature. Globally, the majority of experimental studies have focused on the hawkmoths (Sphingidae) and other specialist pollinators, leaving a substantial gap in knowledge concerning the role of smaller and more generalist moths as pollinators. New Zealand lacks native Sphingidae; however, members of Geometridae, Noctuidae and Erebidae, all identified as pollinators globally, are mentioned as flower-visitors in New Zealand more than expected given their family sizes. In addition to these families, Oecophoridae are mentioned as flower-visitors in New Zealand but this has not been documented globally, suggesting new mutualisms may have evolved in New Zealand. Eight plant families: Alseuosmiaceae, Argophyllaceae, Campanulaceae, Gentianaceae, Goodeniaceae, Montiaceae, Pittosporaceae and Stylidiaceae, were mentioned in the context of moth pollination in New Zealand, but not in the global literature. The Orchidaceae family is most frequently mentioned in the context of moth pollination globally, but was not mentioned at all in the New Zealand literature, despite two endemic genera, Winika and Earina, showing floral features suggestive of moth pollination. The evidence to support pollination by moths in New Zealand comes predominantly from observations of flower-visitation and assumptions based on floral features. As this is not proof of effective pollen transfer, detailed experimental studies are required before the importance of moths as pollinators in New Zealand can be accurately gauged.
