Chrysomela scripta, Plagiodera versicolora (Coleoptera: Chrysomelidae), and Trichoplusia ni (Lepidoptera: Noctuidae) Track Specific Leaf Developmental Stages
It is well recognized that host-specialized folivores prefer to feed on young in comparison to old leaves. However, the capacity of young leaf feeders to track speciÞc leaf developmental stages has not been clearly demonstrated. Using three insect folivores and two plant species, we show that nitrogen (N) fertilization changes leaf development and that herbivores track these changes in leaf dev...
متن کاملCharacterization of digestive α- and β-glucosidases in the midgut of Plagiodera versicolora Laicharting (Coleoptera: Chrysomelidae)
سوسک برگخوار بید Plagiodera versicolora یکی از آفات مهم درختان جنگلی در دنیا از جمله ایران میباشد. در پژوهش حاضر، فعالیت آلفا و بتا- گلوکوزیداز در معده میانی حشره کاملP. versicolora بررسی شد. نتایج نشان داد که فعالیت آلفا- گلوکوزیداز بیشتر از بتا-گلوکوزیداز بود. pH بهینه برای فعالیت آلفا و بتا- گلوکوزیداز بهترتیب 6 و 9 بهدست آمد. همچنین دمای بهینه فعالیت این دو آنزیم بهترتیب 30 و 25 درجه...
متن کاملnutritional indices of the willow leaf beetle, plagiodera versicolora (coleoptera: chrysomelidae) on different host plants
nutritional indices of the willow leaf beetle, plagiodera versicolora laicharting, third instar larvae and adults were studied on four host plants including salix alba l., salix aegyptica l., populus caspica bornm.and populus alba l.at 22 ± 2 ºc, 70 ± 10% r.h., and a photoperiod of 16:8 h (l: d). the results showed that the highest consumed food by the larvae and adults (148.5 ± 18.0 and 175.21...
متن کاملcharacterization of digestive α- and β-glucosidases in the midgut of plagiodera versicolora laicharting (coleoptera: chrysomelidae)
the imported willow leaf beetle, plagiodera versicolora is one of the main pests of forest trees worldwide including iran. activities of α- and β-glucosidases in the midgut of p. versicolora adults were studied in this research. the results showed a higher α- glucosidase activity of adultsthan β-glucosidase. the optimal phs for α- and β-glucosidases activities were found to be 6 and 9, respecti...
متن کاملcharacterization of digestive α-amylase in the midgut of willow leaf beetle plagiodera versicolora (coleoptera: chrysomelidae)
willow leaf beetle, plagiodera versicolora is an important pest of willow trees that feeds on the leaves both as larvae and as adults. -amylases (ec 3.2.1.1) are the major insect digestive enzymes that catalyze the endohydrolysis of long -1,4-glucan chains such as starch and glycogen. in the current study, -amylase activity was studied in the midgut of larvae and adults of p. versicolora. am...
