Description
MOSQUITO WITH PHMQL MOSQUITO CONTROL This invention relates to methods for the control of mosquitoes and particularly to methods for the disruption or ruption of the life cycle of mosquitoes by contacting mosquito larvae or exposing them an effective amount of a pound of the formula wherein R is or alkoxy or maximum of 6 carbon The preferred compounds of this group are those in which the butyl groups are ortho to the hydroxyl Previously known methods for mosquito control have traditionally centered on the use of insecticides or larvacides and more recently on insect chemosterilants These past efforts have met with only a modicum of and the results have been and In accordance with this it has now been found that members of the insect family can be readily and effectively controlled by subjecting mosquito or their to an effective amount of one or more compounds of the present these compounds have no immediate effect upon the and do not interfere with the actual formation to the pupal The resultant remain fail to develop and die before the emergence of adult These compounds are therefore not larvacidal in their but their effectiveness is dependent upon a novel biological They are such ae the house as well as those of the genera and The compounds of the present invention can be readily prepared by known For seemed is prepared by the direct alkylation of with laobutylene in an acidic followed by The alkoxy and compounds are most prepared by in the para and reacting the resultant halophenpl with a merca an aloohol in the presence of triethylamlnef Compounds under consideration includeι butylphenol butylphenol ertiary 2 2 2 2 butylphenol butylphenol The larvae of the mosquito to be controlled have a water habitat and therefore the compound of this invention can be added per se to the formulated with a solid carrier and cast upon the surface of the or sprayed upon the water in the form of a solution or liquid provided the amount applied is an effective Although the compounds of this invention are useful per se in controlling it is preferable that they be applied directly to the mosquito larvae their habitat in a dispersed form in a suitable extending The suitable extending agents for liquid formulations include organic solvents such as methyl ethyl heptane and the like higher liquid alkanes and petroleum fractions boiling under 400 and having a flash point above about 80 When solid formulations are the extending agents that can be used include tricalcium calcium diatomaceous wood flour and the which are preferably reduced to a particle size of about 5 microns or less In most it is preferred to use a surface active agent to facilitate dispersion of the active compounds throughout the aqueous habitat of the mosquito The compounds of the present invention can be used alone or in combination with other pesticidal agents to broaden the spectrum of activity obtained with a single The concentration of the are usually applied to the aqueous habitat in cient quantity to provide a concentration between about and about 5 The value of the compounds under consideration is greatly enhanced by their specificity of their exceedingly low mammalian toxicity and their lack of toxicity toward fish For when fed orally to had a of and when applied dermally to rabbits exhibited a MLD greater than In the same compound has no effect whatsoever on guppies at a concentration of 10 ppm over a period of 48 The unusual activity of the compounds of the present invention is illustrated by the A base solution of the compound to be evaluated is prepared by dissolving gram thereof in sufficient acetone to provide a by weight solution Then of this acetone solution is pipetted into a 25 x 200 culture tube containing sufficient distilled water to provide trations of 2 and of the compound to be The tube is stoppered and shaken vigorously to facilitate plete mixing of its Thereupon approximately 25 early instar yellow fever mosquito larvae are ferred to the tube with the aid of a The larvae are then held in the tube at 25eC for seven at the end of which time mortality observations are The results in percent kill of the resultant pupae at concentrations of 2 and obtained are set forth COMPOUND ppm ppm 2 2 2 2 By analogous compounds such as 2 and exhibited no activity when the test procedure described above was using these compounds instead of the compounds of the present While this invention has been described with respect to certain embodiments it is to be understood that it is not so and that variations and modifications thereof obvious to those skilled in the art can be made without departing from the spirit or scope MOSQUITO CONTROL Abstract of the Disclosure Method of preventing mosquito larvae from developing into the adult stage by exposing the mosquito larvae to a having an alkoxy or a thioalkyl group in the insufficientOCRQuality
Claims (1)
1. P.A. 36955/11 WHA IS CLAIMED IS I 1..
