Embodiment 1

[0079] Example 1 - Use of labial gland extract as a termite attractant

[0080] To prepare the labial gland extract, termites were killed and the paired labial glands were removed. The labial glands were ruptured by freezing at -20°C for 15 minutes and extracted with 0.6 ml of water for 12 hours at room temperature. The extracts were then frozen at -20°C until use. In Table 1 the labial gland extracts prepared and tested are listed. Chemical analysis of each extract for the presence of p-hydroquinone was found to be present in all extracts. Selected extracts were used in bioassays to assess feeding selectivity as shown in Table 1 below.

Embodiment 3

[0100] Example 3 - lure method

[0101] The lure of termites by p-hydroquinone sources includes both olfactory and gustatory stimulation. Hydroquinone was tested for long-range attraction (smell) in empty and sand-filled plastic containers (14.5 cm internal diameter, 1 cm high, covered with glass slides) colonized by termites via silicone tubes Containers are connected. Experiments were carried out with Darwin's Australian termites and Copotic termites. For each test, two pieces of treated filter paper (25ng-25μg p-hydroquinone and water as control) were placed on the opposite positions of the designated place. The orientation of the tunnels / tunnels built by worker ants and their behavior were evaluated according to the position of the filter paper. In all experiments the tunnels / tunnels built by both termites were oriented towards the p-hydroquinone treated filter paper and none towards the control filter paper. Termites usually walk slowly in a zigzag pattern when foragi...

Abstract

A feeding stimulant for stimulating feeding activity in termites, comprising a compound having at least two OR groups, each of which is a substituent of an aryl moiety, and R is hydrogen or an organic group, and addition compounds thereof.

Description

technical field [0001] The present invention relates to termite attractants and / or feeding stimulants, and more particularly to attractants and / or feeding stimulants for termite baits and as one of the components of termiticidal compositions. Background technique [0002] Organochlorines have been used for decades for termite control all over the world, including Australia. Since the ban on the use of organochlorines for termite control in Australia in 1995, and earlier or similar times in other countries, efforts have been made to develop alternative termite control systems. Poisonous bait systems for the control of live termite infestations have gradually become the main control option for this situation. [0003] In the bait system, the termites are provided with a substrate that the termites will consume preferentially over other food sources suitable for the termite population. Termites either feed on the long-lasting, non-rejection-lethal product added to the food (s...
