  • PURIFICATION AND CHARACTERIZATION OF β‐GLUCOSIDASE FROM GREATER
           WAX MOTH Galleria mellonella L. (LEPIDOPTERA: PYRALIDAE)
    • Authors: Hatibe Ertürk Kara; Yusuf Turan, Aylin Er, Mesut Acar, Sabiha Tümay, Selma Sinan
      Abstract: The greater wax moth, Galleria mellonella, is one of the most ruinous pests of honeycomb in the world. Beta‐glucosidases are a type of digestive enzymes that hydrolytically catalyzes the beta‐glycosidic linkage of glycosides. Characterization of the beta‐glucosidase in G. mellonella could be a significant stage for a better comprehending of its role and establishing a safe and effective control procedure primarily against G. mellonella and also some other insect pests. Laboratory reared final instar stage larvae were randomly selected and homogenized for beta‐glucosidase activity assay and subsequent analysis. The enzyme was purified to apparent homogeneity by salting out with ammonium sulfate and using sepharose‐4B‐l‐tyrosine‐1‐naphthylamine hydrophobic interaction chromatography. The purification was 58‐fold with an overall enzyme yield of 29%. The molecular mass of the protein was estimated as ca. 42 kDa. The purified beta‐glucosidase was effectively active on para/ortho‐nitrophenyl‐beta‐d‐glucopyranosides (p‐/o‐NPG) with Km values of 0.37 and 1.9 mM and Vmax values of 625 and 189 U/mg, respectively. It also exhibits different levels of activity against para‐nitrophenyl‐β‐d‐fucopyranoside (p‐NPF), para/ortho‐nitrophenyl β‐d‐galactopyranosides (p‐/o‐NPGal) and p‐nitrophenyl 1‐thio‐β‐d‐glucopyranoside. The enzyme was competitively inhibited by beta‐gluconolactone and also was very tolerant to glucose against p‐NPG as substrate. The Ki and IC50 values of δ‐gluconolactone were determined as 0.021 and 0.08 mM while the enzyme was more tolerant to glucose inhibition with IC50 value of 213.13 mM for p‐NPG.

  • DIETARY LUFENURON REDUCES EGG HATCH AND INFLUENCES PROTEIN EXPRESSION IN
           THE FRUIT FLY Bactrocera latifrons (HENDEL)
    • Authors: Chiou Ling Chang; Scott Geib, Il Kyu Cho, Qing X. Li, David Stanley
      Abstract: Lufenuron (LFN), a chitin synthase inhibitor, impacts the fertility of Ceratitis capitata, Bactrocera dorsalis, B. cucurbitae, and B. latifrons. We posed the hypothesis that LFN curtails egg hatch in the solanaceous fruit fly, B. latifrons. In this study, newly emerged virgin adults were sexed and fed for 12 days with varying concentrations of LFN‐laced agar diets until sexual maturation. Eggs were collected from 12‐d‐old adults and the egg hatch was assessed. Egg hatch decreased in adults reared on LFN‐treated diets. LFN‐treated media did not influence fertility after one gender was reared on experimental and the other on control media before mating. Exposure to LFN‐treated medium after mating led to reduced egg hatch. We infer that LFN is not a permanent sterilant, and reduced egg hatch depends on continuous exposure to dietary LFN after mating. Proteomic analysis identified two differentially expressed proteins, a pheromone binding protein and a chitin binding protein, between adults maintained on LFN‐treated and control diets. Expression of two genes encoding chitin synthase 2, and chitin binding protein, was altered in adults exposed to dietary LFN. LFN treatments also led to increased expression of two odorant binding proteins one in females and one in males. We surmise these data support our hypothesis and provide insight into LFN actions.

  • TRITERPENE ACIDS FROM APPLE PEEL INHIBIT LEPIDOPTERAN LARVAL MIDGUT
           LIPASES AND LARVAL GROWTH
    • Authors: John T. Christeller; Tony K. McGhie, Joanne Poulton, Ngaire P. Markwick
      First page: 137
      Abstract: Fruit extracts from apple, kiwifruit, feijoa, boysenberry, and blueberry were screened for the presence of lipase inhibitory compounds against lepidopteran larval midgut crude extracts. From 120 extracts, six showed significant inhibition with an extract from the peel of Malus × domestica cv. “Big Red” showing highest levels of inhibition. Because this sample was the only apple peel sample in the initial screen, a survey of peels from seven apple cultivars was undertaken and showed that, despite considerable variation, all had inhibitory activity. Successive solvent fractionation and LC‐MS of cv. “Big Red” apple peel extract identified triterpene acids as the most important inhibitory compounds, of which ursolic acid and oleanolic acid were the major components and oxo‐ and hydroxyl‐triterpene acids were minor components. When ursolic acid was incorporated into artificial diet and fed to Epiphyas postvittana Walker (Tortricidae: Lepidoptera) larvae at 0.16% w/v, a significant decrease in larval weight was observed after 21 days. This concentration of ursolic acid is less than half the concentration reported in the skin of some apple cultivars.

  • cDNA CLONING AND HETEROLOGOUS EXPRESSION OF AN
           ENDO‐β‐1,4‐GLUCANASE FROM THE FUNGUS‐GROWING
           TERMITE Macrotermes barneyi
    • Authors: Jinfeng Ni; Yan Wu, Chao Yun, Menglan Yu, Yulong Shen
      First page: 151
      Abstract: Major β‐glucosidase (BG) and endo‐β‐1,4‐glucanase (EG) activities were localized to the midgut of the fungus‐growing termite Macrotermes barneyi. Previously, we obtained the endogenous BG gene (MbmgBG1) from the midgut of M. barneyi. Here, we report the cDNA cloning of another endogenous cellulase, the EG protein MbEG1. This cellulase was partially purified from crude extract of the midgut of worker termites using zymogram analysis. Based on the N‐terminal amino acid sequence and using rapid amplification of cDNA ends (RACE), a full‐length cDNA of 1,843 base pairs was obtained. This encoded 448 amino acids and the sequence was similar to that of the members of glycoside hydrolase family 9. The MbEG1 transcript was detected primarily in the midgut using quantitative real‐time polymerase chain reaction (PCR). To confirm functional activity of MbEG1, heterologous expression was conducted in both Escherichia coli and Pichia pastoris expression systems. Results indicated that MbEG1 could be functionally expressed in P. pastoris. This study provides the information that may facilitate understanding of cellulolytic systems in fungus‐growing termites.

  • COENZYME Q10 TREATMENTS INFLUENCE THE LIFESPAN AND KEY BIOCHEMICAL
           RESISTANCE SYSTEMS IN THE HONEYBEE, Apis mellifera
    • Authors: Aneta Strachecka; Krzysztof Olszewski, Jerzy Paleolog, Grzegorz Borsuk, Milena Bajda, Magdalena Krauze, Malwina Merska, Jacek Chobotow
      First page: 165
      Abstract: Natural bioactive preparations that will boost apian resistance, aid body detoxification, or fight crucial bee diseases are in demand. Therefore, we examined the influence of coenzyme Q10 (CoQ10, 2,3‐dimethoxy, 5‐methyl, 6‐decaprenyl benzoquinone) treatment on honeybee lifespan, Nosema resistance, the activity/concentration of antioxidants, proteases and protease inhibitors, and biomarkers. CoQ10 slows age‐related metabolic processes. Workers that consumed CoQ10 lived longer than untreated controls and were less infested with Nosema spp. Relative to controls, the CoQ10‐treated workers had higher protein concentrations that increased with age but then they decreased in older bees. CoQ10 treatments increased the activities of antioxidant enzymes (superoxide dismutase, GPx, catalase, glutathione S‐transferase), protease inhibitors, biomarkers (aspartate aminotransferase, alkaline phosphatase, alanine aminotransferase), the total antioxidant potential level, and concentrations of uric acid and creatinine. The activities of acidic, neutral, and alkaline proteases, and concentrations of albumin and urea were lower in the bees that were administered CoQ10. CoQ10 could be taken into consideration as a natural diet supplement in early spring before pollen sources become available in the temperate Central European climate. A response to CoQ10 administration that is similar to mammals supports our view that Apis mellifera is a model organism for biochemical gerontology.

  • cDNA CLONING AND TRANSCRIPTIONAL EXPRESSION PROFILES OF A HEXAMERIN IN THE
           ORIENTAL FRUIT FLY, Bactrocera dorsalis
    • Authors: Meng‐Chen Tsai; Cheng‐Lung Tsai, Mei‐Er Chen
      First page: 180
      Abstract: A Bactrocera dorsalis hexamerin (BdAr) cDNA was cloned (GenBank accession no. KF815528), and its transcriptional expression profiles were determined. The complete 2,530‐bp cDNA encodes a 780‐amino acid protein with a predicted molecular mass of 94.01 kDa. The proportions of phenylalanine (7.8%), tyrosine (11.2%), and methionine (2.6%) in BdAr as well as all other amino acids are reported. BdAr transcripts were detected in the brain, flight muscle, foregut, Malpighian tubules, and fat body. In the larval stage, BdAr transcripts were expressed in the early third instar and increased in the late third instar. In pupae, the highest expression of BdAr mRNA was present on day 1, then declined and persisted through day 2 to day 8. In adult females, the relative expression of BdAr was significantly higher on day 0 and day 1 compared to day 6 to day 10 while it was highest in newly eclosed adult males. The comparison of the BdAr expression between 8–10‐day‐old males and females showed a higher level in females. Our phylogenetic analysis results suggest to us that BdAr is similar to Drosophila larval serum protein 1γ.

  • Hormonal and nutritional regulation of insect fat body development and
           function
    • Authors: Ying Liu; Hanhan Liu, Shumin Liu, Sheng Wang, Rong‐Jing Jiang, Sheng Li
      Pages: n/a - n/a
      Abstract: The insect fat body is an organ analogue to vertebrate adipose tissue and liver and functions as a major organ for nutrient storage and energy metabolism. Similar to other larval organs, fat body undergoes a developmental “remodeling” process during the period of insect metamorphosis, with the massive destruction of obsolete larval tissues by programmed cell death and the simultaneous growth and differentiation of adult tissues from small clusters of progenitor cells. Genetic ablation of Drosophila fat body cells during larval‐pupal transition results in lethality at the late pupal stage and changes sizes of other larval organs indicating that fat body is the center for pupal development and adult formation. Fat body development and function are largely regulated by several hormonal (i.e. insulin and ecdysteroids) and nutritional signals, including oncogenes and tumor suppressors in these pathways. Combining silkworm physiology with fruitfly genetics might provide a valuable system to understand the mystery of hormonal regulation of insect fat body development and function. © 2009 Wiley Periodicals, Inc.
