Neotenic Phenotype and Sex Ratios Provide Insight into Developmental Pathways in Reticulitermes flavipes (Isoptera: Rhinotermitidae)
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...
متن کاملMetabolism of Imidacloprid in Workers of Reticulitermes flavipes (Isoptera: Rhinotermitidae)
The chloro-nicotinyl insecticide imidacloprid is used extensively as a soil treatment against subterranean termites. We conducted the Þrst study of the metabolic fate of imidacloprid in termites, by exposing workers of the eastern subterranean termite, Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae) to radiolabeled imidacloprid through topical application and ingestion. Several day...
متن کاملSex Ratios in Field Populations of Reticulitermes spp. (Isoptera: Rhinotermitidae) on Sapelo Island, Georgia, USA
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 ...
متن کاملIsolation and Evaluation of Beauveria bassiana for Control of Coptotermes formosanus and Reticulitermes flavipes (Isoptera: Rhinotermitidae)
Six Beauveria bassiana (Balsamo) Vuillemin isolates were obtained from Reticulitermes flavipes (Kollar) and Coptotermes formosanus Shiraki in the U.S. and China. These isolates, plus the B. bassiana isolate 26037 from American Type Culture Collection that was isolated from Colorado potato beetle (Leptinotarsa decemlineata (Say)) were compared against C. formosanus and R. flavipes in the laborat...
متن کاملFactors that Influence Tunneling in the Eastern Subterranean Termite, Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae)1
Although subterranean termite (Isoptera: Rhinotermitidae) foraging behavior involves the construction of gallery systems in soil, few studies have examined how colony size or soil environmental factors influence rates of construction and morphology of gallery systems. In this study, we investigated the effects of soil texture, soil moisture, and termite density on the rate of tunnel constructio...
