Climatic matching and pre-release performance evaluation were useful predictors of parasitoid establishment in a retrospective analysis of a classical biological control program against Bemisia tabaci biotype ‘‘B’’ in the USA. Laboratory evaluation of 19 imported and two indigenous parasitoid species in quarantine on B. tabaci showed that the Old World Eretmocerus spp, had the highest attack ra...
Intracellular symbionts of arthropods have diverse influences on their hosts, and their functions generally appear to be associated with their localization within the host. The effect of localization pattern on the role of a particular symbiont cannot normally be tested since the localization pattern within hosts is generally invariant. However, in Israel, the secondary symbiont Rickettsia is u...
The chromosomes obtained from scarab beetle Gymnopleurus mundus Wied., 1819 of subfamily Scarabaeinae were studied using standard staining and C-banding. The karyotype is comprised of 14 chromosomes with meioformula, 6AA+Xyp. The analysis of constitutive heterochromatin (CH) revealed small blocks located in the centromeric region of all chromosomes. Some of the anomalies like polypoidy, deconde...
Many intracellular microbial symbionts of arthropods are strictly vertically transmitted and manipulate their host's reproduction in ways that enhance their own transmission. Rare horizontal transmission events are nonetheless necessary for symbiont spread to novel host lineages. Horizontal transmission has been mostly inferred from phylogenetic studies but the mechanisms of spread are still la...
Spatially distributed control is a design principle for systems which include many repeating units with overlapping regions of influence. Transfer functions in both time and spatial dimensions are used to design a controller for applications from a paper mill to the next generation space telescope. This thesis is part of a project known as HeatAl to create a hardware system for demonstration ex...
