Abstract

A substantially biodegradable device for sustained release of an insect attractant, the device comprising a blend of: a substantially biodegradable or bio-erodable polymer, or a polymer which is bioerodable when contained in the blend; a cellulose filler material; and an insect affecting material.

Description

INSECT ATTRACTING DEVICE
The present invention is concerned with a device for sustained or controlled release of a formulation, such as a semiochemical, for example a pheromone or the like.
Many devices currently employed as carriers for sustained release of insects' semiochemicals such as attractants, pheromones or the like, include a blend of the insect attractant and plastics (including PVC) . For certain attractants the preferred polymer has been PVC because it gives the required longevity to the product. Although this system works well for sustained release of the insect attractant, the PVC is considered a problem because the product is left in the field at the end of the season. Therefore, years of use of PVC based device results in accumulation of plastic build up in the soil.
It is therefore an aim of the present invention to alleviate at least some of the disadvantages identified above .
It is a further aim of the present invention to provide a device for sustained release of an insect attractant. Therefore, according to a first aspect of the present invention, there is provided a. substantially biodegradable device for sustained release of an insect attractant, the device comprising a blend of: a substantially biodegradable or bio-erodable polymer, or a polymer which is bio-erodable when contained in the blend; a cellulose filler material; and an insect affecting material.
The polymer may be any polymer known in the field of plastics to be substantially biodegradable, bio-erodable, or substantially biodegradable or bio-erodable when included in the blend. However, ethylene vinyl acetate (EVA) based polymers have been shown provide useful substrates being essentially inert and not containing any noxious compounds but EVA alone would not be substantially bio-erodable; it is the combination of EVA with the cellulose filler material that renders the device substantially bio-erodable. Advantageously, the cellulosic material absorbs the pheromone thereby achieving a slower release rate than the polymer material alone.
The cellulosic material may be cellulose itself, hemicellulose, a wood fibre, wood powder, wood chip, sawdust, starch, lignin or the like. The insect affecting material may be a semiochemical or the like. The semiochemical may include attractants, repellents, Pheromones and Kairomones (which benefit the receiver, to the detriment of the emitter) .
A particularly preferred pheromone blend is Z-ll-16:Al/Z-9- 16:A1/Z-13-18 :A1 when the insect to be affected is the rice stem borer. Advantageously, the navigational cue of the male rice stem borer will be adversely affected by the device according to the present invention thereby disrupting mating patterns. However, suitable pheromones for other insect pests may include (Z,E) (Z, Z) -7, 11-16 :Ac (Pink Boll Worm), Z,E-7, 9-12 :Ac (Lobesia botrana) , E, E-8, 10-
12 : 01 (Codling moth), E-5-10 :Ac/E-5-10 :Ol (Anarsia lineatella) , or E, Z-2, 13-18 :Ac/E, Z-3 , 13-18 :Ac (Zeuzera pyrina) .
The device typically comprises the cellulose material and the biodegradable or bio-erodable polymer in a combined amount in the range 75% to 95% by weight of the device. A particularly preferred amount is in the range 83% to 91% by weight of the device.
The device may be in the form of a tube having internal flutes, the internal flutes permitting attachment of the device to a stake. Devices having similar configurations are known by people skilled in the art.
Alternatively, it is envisaged that the device may be in the form of an elongate strip having two apertures therein. Preferably, each aperture is arranged at opposed end of the elongate strip. In use, the user would typically push a stake or the like, through the first aperture and subsequently through the second aperture, such that the device forms a ΛC shape on the stake.
The strip preferably has a thickness in the range 1mm to 3.5mm, preferably 2mm to 2.5mm.
Preferred presentations of the finished device are given in table 1 below.

The present invention further extends to a method of manufacturing a device according to the first aspect of the present invention .
The device is substantially as described hereinbefore with reference to the first aspect of the present invention.
Experimental Data
Experiment 1 : Formulation Development
Testing Wood filled polymers.
Wood fibre is used to fill different types of thermopolymers . The wood fibre is a natural material and is biodegradable. Elvax 350 is used as the substantially biodegradable polymer. The pheromone used is Z11-16A1.
Component w/w
Fibre/Elvax compound 88% Z11-16A1 10%
BHT 1%
Waxoline Black 1%
The formulation was extruded, reground and then re-extruded to achieve homogenous mixing of the components.
A release rate study was set up using a product sold by Agrisense-BCS Ltd under the trade mark Selibate CS as control. The Selibate product includes a non-biodegradable polymer (typically PVC) .
The results from this experiment are given in Figure 1.
Conclusions : In the field the standard formulation releases 75% of its pheromone over a 150 day period (measured from field collected samples in 2002) . In an older study from 1994 (see Figure 2) the standard formulation released about 50% of its pheromone over a 2 month period covering most of the rice season. The results indicate that the standard formulation is releasing slower than required and that a substantial amount of the pheromone is still in the polymer at the end of the season in mid September.
Both the formulation types appear to be releasing very slowly under lab conditions with only ~35% of the Z-029 (Z11-16:A1) lost from the wood polymer and ~25% from the standard Selibate over a period of 115 days. The release area has a daily temperature oscillation from ~15°C to 30°C. This is cooler but not enormously different to the ambient temperature conditions experienced in Spain. The major difference is the absence of direct solar radiation in the lab trials. This would substantially heat the black Selibate devices and raise the release rate. The net result is that the results obtained are purely comparative and have little relation to the products expected field life.
The trial demonstrates that the new cellulose based formulation is faster releasing than the standard Selibate control . Given that a lot of pheromone remains in the standard formulation at the end of the season the device according to the present invention may benefit from a faster release rate.
The present invention will now be described with reference to the accompanying drawings which are given by way of example only, wherein:
Figure 1 represents the release rate of wood based S CS formulations;
Figure 2 represents the pheromone release rate of Selibate CS tube formulation, Spain 1994;
Figure 3 represents a plan view of the device according to the present invention; and
Figure 4 represents a device according to the present invention in use.
Referring to Figures 3 and 4, where like numerals have been used to represent like parts, there is provided an insect attracting device generally represented by the numeral 1.
The device 1 is manufactured from a blend of the following components :
Fibre/Elvax compound 88% Z11-16A1 10%
BHT 1%
Waxoline Black 1%
The blend is extruded to form an elongate strip having a typical length of 45mm and a width w of 25mm. A first crescent shaped slit 2 and a second crescent shaped slit 3 are arranged at opposed ends of device 1.
In use, a stake 4 is pushed through slit 2 and subsequently through slit 3 such that the device 1 forms a C-shape about stake 4. The device 1, when positioned on the stake, is then placed in the desired place (typically a field) so as to attract the desired insect.
Experiment 2
Full pheromone formulation extruded in thicker flat profile extrusion of the wood filled Elvax formulation. This time without pre-compounding of the wood and polymer. Mix components into the blend separately. Stir until mix is a homogeneous colour. Feed into the extruder and use plunger to push mix into the extruder screw.
Component w/w
Elvax 350 46.00% Fibretron 40 30.00%
Vegetable oil 12.70%
Z11-16A1 8.33%
Z9-16.A1 0.83%
Z13-18.A1 0.83% BHT 1.00%*
Waxoline Black 0.30%
Material extruded reasonably well though there was still a tendency for the edges to be stretched and lumpy.
A release rate study using Selibate CS as control was set up.
Release rate study was done on a 4mm string formulation. In order to match the release rate any alternative presentation should attempt to match the surface/volume ratio. The 2.3mm thick most closely matches this.
Conclusions:
The quality of the extrusion is affected markedly by the extrusion temperature. Cooling the head made for a better profile. When cooled to far, however, extrusion stopped so a compromise temperature, in this case ~100°C seems appropriate.
Experiment 3
Field trial materials for 2003 trials Extruding a 3.5mm x 25mm profile. It was found to be extremely difficult to extrude the formulation if the pheromone was first absorbed into the wood powder or into the polymer/wood mixture before extrusion. This remained the case even if the material was allowed to stand for a long time and the pheromone to absorb into the polymer. In order to overcome this problem it was found to first absorb the pheromone into the polymer then add the wood chip and oil. As a consequence slightly more oil was needed to lubricate the wood powder.
Final formulation was
Component w/w
Elvax 350 46.00%
Z11-16A1 8.33% Z9-16.A1 0.83%
Z13-18.A1 0.83%
BHT 1.00%
Waxoline Black 0.50%
Above mixed and absorbed before addition of following;
Fibretron 40 35.00%
Vegetable oil 12.0%
Formulation extruded well once processing parameters had been optimised.
