Sex Ratios in Field Populations of Reticulitermes spp. (Isoptera: Rhinotermitidae) on Sapelo Island, Georgia, USA
نویسندگان
چکیده
Social insects provide some of the most striking examples of sexual division. Thirty termite inspection ports were sampled four times in 11 months (September 2008 – July 2009). A total of 90 collections of a not-yet described Reticulitermes spp. were examined to estimate sex ratios. The range of sex ratios (male to female) observed, by caste, were: 0.49-3.50 for workers, 0.75-5.25 for soldiers and 0.02-26.00 for nymphs. These results provide new minimum and maximum values of sex ratios for each caste in Reticulitermes and reveal that there is a great deal of variation in field population sex ratios. The variation could be attributed to sample size, termite population movement between sample dates, and species differences. The data are discussed relative to interpretation of termite sex ratio data.

We characterized the cold tolerance of natural populations of the Eastern subterranean termite (Reticulitermes flavipes (Kollar) [Isoptera, Rhinotermitidae]) in southwestern Ontario, Canada. We measured cold tolerance in workers from six colonies of termites established from Pelee Island in Lake Erie, and Point Pelee National Park. The mean critical thermal minimum, at which termites entered ch...

Several thousand Reticulitermes flavipes (Kollar) including worker, nymph, soldier, neotenic and alate castes were collected from three pine logs brought into the laboratory on dates five years apart. The neotenics, all nymphoid, were divided into three groups based on the extent of cuticle pigmentation and termed regular neotenics (RN), black-headed neotenics (BHN) or black neotenics (BN). All...

The diurnal ßights of Reticulitermes spp. have been reported to occur in the spring and early fall in northern California. From the spring of 1994 until the fall of 2001, we collected hundreds of alates of Reticulitermes spp. cuticular hydrocarbon phenotypes CA-A/A and CA-D during ßights from multiple locations in the San Francisco Bay Area. As predicted, there were two ßight seasons: one in th...
