Biological Activities of the Analogs of the Aggregation Pheromone of Tribolium castaneum(Coleoptera : Tenebrionidae)

Antennal Sensilla of the New World Screwworm Fly, <I>Cochliomyia hominivorax</I> (Diptera: Calliphoridae)

“…These can affect long-range attraction and the ability of individuals to identify and locate mates or hosts; sometimes they act as alarms, induce trail-following, and influence oviposition or aggregation behavior (van der Goes van Naters & Carlson 2006). It has been shown that T. castaneum responds to grain-emitted volatiles and an aggregation pheromone created by feeding males that is attractive to males and females (Suzuki et al 1984;Lu et al 2011). The beetle is monitored in food facilities using a variety of traps baited with aggregation pheromones and food-based kairomone lures (Barrer 1983;Burkholder 1990;Chambers 1990;Mullen 1992;Cox 2004;Campbell et al 2009).…”

Anatomical localization and stereoisomeric composition of Tribolium castaneum aggregation pheromones

“…This pheromone was 54 identified as 4,8-dimethyldecanal (DMD), which has two asymmetric carbons at C-4 and C-8 55 (Suzuki, 1980;Suzuki et al, 1984). Suzuki (1980) synthesized a mixture of all four 56 stereoisomers of DMD and found it to be less active than the natural pheromone (Suzuki,57 1981; Suzuki et al, 1987 would have reduced pheromone collection relative to results from the current study.…”

Insect pheromone synthesis in Brazil: an overview

“…In 1980 80 later found that a mixture of the isomers (4R,8R)-and (4R,8S)-, in a ratio of 8:2, was about 10 times more active than (4R,8R)-23 alone.…”
