A gynandromorph is an organism combining both female- and male-type tissues. While the vast majority of studies have described the morphology of gynandromorphs, their sexual behaviours remain under-explored. We studied a predominantly bilateral gynandromorph specimen of the predatory wasp Discoelius dufourii (Hymenoptera: Vespidae: Zethinae) reared from a trap-nest. In addition to describing the morphology, we explored the gynandromorph’s response to a conspecific female, comparing it with the behavioural interactions between normal males and females of D. dufourii and the phylogenetically related D. zonalis. For most specific behavioural elements, males of both Discoelius species exhibited a greater frequency and a higher probability of occurrences of the behaviour than did females. However, aggression and plopping behaviours were prevalent in females. The gynandromorphic specimen demonstrated behavioural activities similar to those of a male, including a relatively frequent mate body antennation and an attempt to mount a female. However, it approached the female less frequently in comparison to conspecific normal males, and it did not demonstrate substrate antennation and jumping, typical of Discoelius male mating behaviour. Based on the parameters of the nest cell, the probability of the development of the gynandromorphic specimen from an unfertilized (male) egg was higher than the probability of development from a fertilized (female) egg.

Abstract Two nests of the wasps Leptochilus alpestris (de Saussure, 1855) and Leptochilus regulus (de Saussure, 1855) collected in the Crimea were described. The nest of L. alpestris was found in the empty snail shell of Monacha fruticola under a stone; it contained one cell sealed with plug made of glued gravel bits. The nest of L. regulus was found in 3 mm hole of a reed stem from trap-nest; it contained 9 cells separated with partitions made of gravel and mud. The unusual larval habit was discovered in L. regulus - they moved mud from the plug of the cell to its bottom before cocoon spinning. Distinctions of the studied nests from ones of the other species of the genus Leptochilus de Saussure, 1853 were discussed.

AbstractVertical, tubular borings, either simple or subdivided into cells by horizontal, spirally ornamented partitions of cemented fine silt, are common in the uppermost part of Unit Q3 of the Quaternary floodplain deposits in the eastern part of the Jeffara Plain. The structures display many features similar to those found in nests constructed by tube-dwelling, solitary wasps and bees. The size of the cells, the spiral construction of the partitions and the general architecture of the cells is closely comparable to the nest structure of the large carpenter bee Xylocopa virginica krombeini Hurd., and it is suggested that the Quarternary nests were constructed by a bee of Xylocopid type.

Abstract The AMAGuides to the Evaluation of Permanent Impairment (AMA Guides) is the most widely used basis for determining impairment and is used in state workers’ compensation systems, federal systems, automobile casualty, and personal injury, as well as by the majority of state workers’ compensation jurisdictions. Two tables summarize the edition of the AMA Guides used and provide information by state. The fifth edition (2000) is the most commonly used edition: California, Delaware, Georgia, Hawaii, Kentucky, New Hampshire, Idaho, Indiana, Iowa, Kentucky, Massachusetts, Nevada, North Dakota, Ohio, Vermont, and Washington. Eleven states use the sixth edition (2007): Alaska, Arizona, Louisiana, Mississippi, Montana, New Mexico, Oklahoma, Pennsylvania, Rhode Island, Tennessee, and Wyoming. Eight states still commonly make use of the fourth edition (1993): Alabama, Arkansas, Kansas, Maine, Maryland, South Dakota, Texas, and West Virginia. Two states use the Third Edition, Revised (1990): Colorado and Oregon. Connecticut does not stipulate which edition of the AMA Guides to use. Six states use their own state specific guidelines (Florida, Illinois, Minnesota, New York, North Carolina, and Wisconsin), and six states do not specify a specific guideline (Michigan, Missouri, Nebraska, New Jersey, South Carolina, and Virginia). Statutes may or may not specify which edition of the AMA Guides to use. Some states use their own guidelines for specific problems and use the Guides for other issues.
