“…Australian native anurans do not respond to the alarm or attractant pheromones produced by cane toad tadpoles [18,38], and so may well ignore these development-suppressing toad pheromones. Sex pheromones have been used as attractants and mating disruptors for biocontrol [6,7,39]. Agricultural scientists exploit allelopathic effects to suppress weed growth [40]; and indeed, the effects we have documented would qualify as allelopathy under some but not all definitions of this term [41].…”

Adaptations to suppress the viability of conspecifics may provide novel ways to control invasive taxa. The spread of cane toads (Rhinella marina) through tropical Australia has had severe ecological impacts, stimulating a search for biocontrol. Our experiments show that cane toad tadpoles produce waterborne chemical cues that suppress the viability of conspecifics encountering those cues during embryonic development. Brief (72 h) exposure to these cues in the egg and posthatching phases massively reduced rates of survival and growth of larvae. Body sizes at metamorphosis (about three weeks later) were almost twice as great in control larvae as in tadpole-exposed larvae. The waterborne cue responsible for these effects might provide a weapon to reduce toad recruitment within the species' invaded range.

“…The first semiochemical to be isolated and identified was the sex pheromone of the silk moth, Bombyx mori L. (Butenandt et al, 1959). In the time since that discovery, extensive research on insect pheromones has resulted in the chemical and/or behavioral elucidation of pheromone components from over 1500 species (Thomson et al, 1999;Tillman et al, 1999).…”

“…Consequently, these two compounds and codlemone are the active ingredients in Isomate-C and -C Plus polyethylene tube dispensers (Pacific Biocontrol Co., Vancouver, WA, USA), which are widely used for mating disruption of codling moth (Thomson et al, 1998).…”

The effect of brief pheromone exposures on responses of codling moth (Cydia pomonella L.) males was tested by flight-tunnel and electroantennogram (EAG) studies. Males were preexposed to pheromone for up to 3 min as they sat in release cages or for shorter times (a few seconds to several min) upon initiating flights or orienting in plumes. Brief exposures to Isomate-C Plus dispensers nearly eliminated moth orientations to 0.1 mg codlemone [(E,E)-8,10-dodecadien-1-ol] and 0.1 mg three-component (codlemone/12OH/14OH, 100:20:5 ratio) lures 15 min later. However, there was no associated change in EAG responses between preexposed and control moths. Behavioral responses of Isomate-C Plus-exposed males were normal 24 hr following exposure. The reduced sexual responsiveness observed following exposure to Isomate dispensers appeared to be associated with an elevation of response threshold. Brief preexposure to 0.1 mg codlemone and three-component lures also reduced orientational behavior of males 15 min later, but to a lesser degree than when preexposed to Isomate-C Plus dispensers. Male behavior following preexposure to a 0.1 mg codlemone/pear ester [(2E,4Z)-2,4-decadienoate] lure (1:1 ratio) was no different from exposure to codlemone only. Orientational disruption in plots treated with 10 dispensers of Isomate-C Plus per tree was 88.3 and 95.9% for 1.0 and 0.1 mg codlemone lures, respectively. Some males did orient to 0.1 mg codlemone lures so we caution that flight-tunnel experiments on preexposure may overestimate the actual pheromone exposure dosage received by feral moths in treated orchards. Importantly, this work documents that a portion of feral males within a population has the capacity to overcome communicational disruption by high densities of Isomate-C Plus dispensers.
