Definitions

  • This invention concerns insecticide emanator mats, and insecticidal formulations for use therewith, as well as methods of combating insects using them.
  • Insecticide emanator devices are well known which comprise a heating element adapted to heat a replaceable insecticide-containing mat to a predetermined temperature, usually about 130-160°C, so as to vaporise the insecticide over a period of time, and provide protection in their vicinity, typically against mosquitos or flies.
  • the insecticidal composition which is often based on a pyrethroid insecticide such as allethrin, is impregnated into the mat, which usually consists of an inert porous substance such as cardboard, wood pulp fibre, textile pulp, synthetic fibres or a porous resin.
  • the typical useful life of such mats is low, being of the order of just 12 hours, which means that they are rather unsuitable where prolonged insect control is required. Attempts to provide greater useful life by increasing the quantity of insecticide present in the mat have failed, apparently because the insecticide tends to degrade on prolonged heating, leading to much reduced, uneven release into the atmosphere.
  • this invention provides a mat for use in an insecticide emanator, said mat containing an insecticidal composition comprising one or more pyrethroid insecticide having a vapour pressure at 25°C of from 0.1 to 200 milliPascals (mPa) , preferably from 0.1 to 100 mPa, especially from 1 to 50 mPa, together with piperonyl butoxide and/or one or more analogues thereof, in a weight ratio of pyrethroid insecticide to piperonyl butoxide and/or its analogues of from 5:1 to 50:1.
  • mPa milliPascals
  • 'analogues' of piperonyl butoxide is used herein to include structurally similar compounds having substantially similar properties, especially analogues or homologues of 5-[ (2-(2-butoxyethoxy)ethoxy)methyl]-l,3- benzodioxole, for example 5-[ (2-(2-butoxyethoxy)ethoxy)- methyl]-l,3-benzodioxole, 5,6-di-[ (2-(2-butoxyethoxy)- ethoxy)methyl]-1,3-benzodioxole or 4 ,5,6-tri-[ (2-(2- butoxyethoxy)ethoxy)methyl]-l,3-benzodioxole.
  • the pyrethroid insecticide is preferably allethrin, or bioallethrin, as individual stereoisomers or mixtures thereof, including in particular the (S)-cyclopentenyl isomer of bioallethrin, and d-allethrin (ie an 80:20 ratio of bioallethrin with the analogous esters of the (lR)-cis acid), which possess a vapour pressure in the defined range.
  • allethrin or bioallethrin
  • bioallethrin ie an 80:20 ratio of bioallethrin with the analogous esters of the (lR)-cis acid
  • the mats of the invention may also be used in conventional, higher temperature emanators particularly if the mat is spaced apart from the heating element.
  • a non-absorbent spacer may conveniently be positioned between the heating element and the mat to provide a suitable temperature reduction at the mat's surface. Any such spacer is preferably such that it does not contact the whole of the mat surface, so as to allow insecticide vapour to escape from the mat.
  • the invention provides a method of combating insects in which a surface of a mat containing an insecticide composition comprising one or more pyrethroid insecticide having a vapour pressure of from 0.1 to 200mPa at 25°C, together with piperonyl butoxide and/or one or more analogues thereof, in a weight ratio of pyrethroid insecticide to piperonyl butoxide and/or its analogues of from 5:1 to 50:1, is heated to a temperature effective to vaporise the insecticide into the atmosphere, eg from 90 to 120°C.
  • the invention provides novel insecticidal compositions which comprise one or more pyrethroid insecticide having a vapour pressure of from 0.1 to 200mPa at 25°C, together with piperonyl butoxide and/or one or more analogues thereof in a weight ratio of pyrethroid insecticide to piperonyl butoxide and/or its analogues of from 5:1 to 50:1.
  • the weight ratio of pyrethroid insecticide to piperonyl butoxide and/or its analogues is preferably from 9:1 to 20:1.
  • the mats of the invention may within reason contain any desired amount of the pyrethroid insecticide, generally reckoned on the basis of 5 to lOOmg, typically about 20mg, of insecticide for each 12 hours intended use. Since the mats are appropriate for use over an extended period, each preferably contains from 140mg to 7.2g of pyrethroid insecticide.
  • the insecticide composition of the invention may contain further solvents, surfactants and adjuvants as required, and optionally a suitable dye to provide a colour change when the mat approaches exhaustion.
  • a suitable dye to provide a colour change when the mat approaches exhaustion.
  • Anthraquinone dyes have been found to be particularly useful in this respect. The invention is illustrated by the following examples, in which:
  • Average evolution rates of pyrethroid insecticide were calculated by subtracting the amount of the insecticide remaining from the amount applied to the mat and dividing by the heating time.
  • Biological efficacy tests were carried out in 2 m 3 glass sided chambers at a temperature of 27°C and 50% relative humidity.
  • the mats were heated in an adjacent fume cabinet for a period of 1 hour prior to the tests to ensure they had reached a constant operating temperature.
  • a batch of at least 50 mosquitoes (Aedes ae ⁇ ypti) was released into the chamber.
  • the heater and mat were then transferred to the centre of the floor of the chamber with power supplied continuously to the heater.
  • the number of mosquitoes knocked down at l minute intervals up to 15 minutes was recorded.
  • the times taken to knock down 50% of the population (KT50) and knock down 95% (KT95) were determined from these data.
  • the temperature of the heater surface was measured using a calibrated thermocouple surface probe attached to a meter. Heat sink compound was used to ensure a good thermal contact between the heater surface and the probe. The average temperature was determined from a series of 8 readings across the heater surface in direct contact with the mat.
  • EBT is a 93% pure technical grade product supplied by Roussel Uclaf containing at least 72% of the (S)- cyclopentenyl isomer of bioallethrin and at least 21% m/m other allethrin isomers;
  • SBA is a 95% pure technical grade product supplied by Roussel Uclaf containing at least 90% of the (S)- cyclopentenyl isomer of bioallethrin;
  • Fat Blue B is an oil soluble anthraquinone dye supplied by Hoechst;
  • Piperonyl butoxide (PB) is the technical grade material 91% pure supplied by Roussel Uclaf;
