Decyl acetate synthesis in the ant, Formica schaufussi (Hymenoptera: Formicidae)

AbstractWorkers of the ant Formica schaufussi did not transfer a specific choice-point response of right- or left-turning (learned on entrance runs in which an opposed-turns alley sequence led to the choice-point) to an equivalent free-turns situation traversed on returns from the food-box to the nest. Variable behavior, however, was evident in both phases of the maze run after the choice-point alternatives had been reversed experimentally. This behavior is attributed to the general excitatory effects of the situational change. The outcome of this study supports previous results for these ants in complex mazes and in single choice-point U-approach mazes. The conclusion is confirmed that choice-point learning in these ants is bound to the situation in which it is established, evidently through a specificity of response to the sensory aspects and the organic conditions peculiar to action in that situation.

Lures for a monitoring system based on sex attractant trapping of Agrotis segetum males were elaborated for Israel and Germany. Various mixtures of (Z)-5-aecenyl acetate, (Z)-7-dodecenyl acetate, (Z)-9-dodecenyl acetate, (Z)-9-tetradecenyl acetate, decyl acetate and dodecyl acetate were tested in 20 different blends. From comparison of all the trap catches a four-component lure consisting of (Z)-5-decenyl, (Z)-7-dodecenyl, (Z)-9-tetradecenyl and dodecyl acetate is recommended for monitoring of A. segetum in both countries.

Abstract A procedure is presented for the quantitative estimation of sucrose diacetate hexaisobutyrate in soft drinks based on quantitative determination of the acetic and isobutyric acid components. The method involves an acidcatalyzed transesterification of the sucrose esters with sulfuric acid in decanol followed by GLC analysis of the resulting decyl acetate and isobutyrate, using hexanoic acid as internal standard. Recoveries of sucrose diacetate hexaisobutyrate from drinks fortified with this compound ranged between 92.8 and 97.8% in calculations based on acetic acid content and between 97.1 and 99.3% in those based on isobutyric acid. The analysis of several commercialjdrinks gave sucrose ester contents ranging from 11.5 to 14.2 mg/10 fluid oz.
