| cry3aa11: a new cry3aa delta-endotoxin from a local isolate of bacillus thuringiensis. | a local isolate of bacillus thuringiensis mm2 had insecticidal activity against the larvae of melolontha melolontha, agelastica alni, leptinotarsa decemlineata and amphimallon solstitiale and produced a 65 kda protein. sds-page profile of b. thuringiensis mm2 was compared with those of 29 different cry3aa producers which verified cry3aa biosynthesis by the isolate. the cry3aa gene of mm2 was cloned, sequenced and the deduced amino acid sequence was compared with the cry3aa sequences of ten diffe ... | 2005 | 16132862 |
| investigations on bacteria as a potential biological control agent of summer chafer, amphimallon solstitiale l. (coleoptera: scarabaeidae). | studying the bacteria of hazardous insects allows the opportunity to find potentially better biological control agents. therefore, in this study, bacteria from summer chafer (amphimallon solstitiale l., coleoptera: scarabaeidae) we isolated and identified the insecticidal effects of bacteria isolated from a. solstitiale and melolontha melolontha l. (common cockchafer, coleoptera: scarabaeidae) and the mixtures of these bacterial isolates were investigated on a. solstitiale larvae. crystals from ... | 2005 | 16273040 |
| dna-based analysis of regurgitates: a noninvasive approach to examine the diet of invertebrate consumers. | dna-based gut content analysis has become an important tool for unravelling feeding interactions in invertebrate communities under natural conditions. it usually implies killing of the consumer and extracting the dna from its food, using either the whole animal or its dissected gut. this post-mortem approach, however, is not suitable for investigating the diet of rare or protected species and also prohibits tracking individual dietary preferences as each consumer can provide trophic information ... | 2012 | 22443278 |
| (r)-acetoin-female sex pheromone of the summer chafer amphimallon solstitiale (l.). | extracts of amphimallon solstitiale (l.), a well known, widely distributed and rather common european scarab beetle, were analyzed by gc-ms and gc-ead. acetoin - (r):(s) > 9:1 - as well as 2,3-butanediol - (2r,3r): (2s,3s):meso = 1:1:9 - were present in extracts of both males and females. although (2s,3s)-butanediol did not show any ead activity, the other compounds elicited strong responses exclusively with male antennae. in contrast, several ead active green leaf volatiles were detected equall ... | 2003 | 12775160 |
