چکیده
mulberry pyralid, glyphodes pyloalis walker is an important pest on mulberry. the essential oil of rosemary rosemarinus officinalis l. (lamiales: lamiaceae) has been investigated on toxicity and physiological characteristics of this moth under controlled conditions. the major compounds of the oil were analyzed as 1, 8 cineol (20.021%), borneol (7.17%), camphor (6.541%), geraniol (6.281%), camphene (5.623%), linalool (4.993%) alpha fenchyl acetate (4.222%) and verbenone (4.147%). lethal and sublethal concentrations (lc10, lc30 and lc50) were estimated 0.77%, 1.18% and 1.59% (v/v) respectively. the essential oil affected the nutritional indices of fourth instar larvae of g. pyloalis. efficiency of conversion of ingested food (eci), efficiency of conversion of digested food (ecd), relative consumption rate (rcr) and relative growth rate (rgr) were reduced in larvae treated with r. officinalis essential oil while approximate digestibility (ad) in treated larvae was significantly increased compared with the control. the essential oil affected the insect’s some key metabolic compounds like; lipid, protein and carbohydrates. similarly this effect was also significant in the activities of certain key enzymes like; alpha- amylase, lipase, protease, glutathione-s-transferase and esterases.

متن کاملIdentification and Partial Characterization of Midgut Proteases in the Lesser Mulberry Pyralid, Glyphodes pyloalis
Proteolytic activities in digestive system extracts from the larval midgut of the lesser mulberry pyralid, Glyphodes pyloalis Walker (Lepidoptera: Pyralidae), were analyzed using different specific peptide substrates and proteinase inhibitors. High proteolytic activities were found at pH 10.0 and a temperature of 50° C using azocasein as substrate. The trypsin was active in the pH range of 9.5-...

Development of Glyphodes pyloalis Walker was studied under laboratory conditions at constant temperatures of 12, 16, 20, 24, 28, 30, 32, and 36 °C. No development occurred at 36 °C. Although eggs hatched at 12 ºC, no larvae were capable of developing to adult stage. At 16 ºC, survival rate was low (4%) and prepupal stage lasted 101.68 ± 11.03 d. Larvae completed development through six stadia a...

متن کاملComparing Essential Oil Composition and Essential Oil Yield of Rosemarinus Officinalis and Lavandula Angustifolia before and Full Flowering Stages
The chemical composition of essential oils and essential oil yield obtained from Rosemarinus officinalis (family Lamiaceae) and Lavandula angustifolia (family Lamiaceae) were determined in two harvesting times. Their essential oil was determined by hydro-distillation, and analysed by GC/MS. The results showed that harvesting time had significant effects on the oil content and compositions in bo...
