## Abstract

Novel dibutylorthobenzylmethoxybenzenes having the structure ##STR1## wherein R is hydrogen, lower alkyl or lower alkoxy and novel dibutylorthocinnamylmethoxybenzenes are disclosed as growth inhibitors for mosquito larvae.

## Claims

### Claim 1

A compound of the structure ##STR26## wherein R is hydrogen, lower alkyl containing from 1 to 6 carbon atoms or lower alkoxy containing from 1 to 6 carbon atoms.

### Claim 2 (depends on 1)

The compound of claim 1 which is 2,4-bis(1,1-dimethylethyl)-6-(phenylmethyl)methoxybenzene.

### Claim 3 (depends on 1)

The compound of claim 1 which is 2,4-bis(1,1-dimethylethyl)-6-[(4-methoxyphenyl)methyl]methoxybenzene.

### Claim 4

A compound of the structure ##STR27##

### Claim 5 (depends on 4)

The compound of claim 4 which is 2,4-bis(1,1-dimethylethyl)-6-(3-phenyl-2-propenyl)methoxybenzene.

### Claim 6

A method of inhibiting growth of mosquito larvae, which comprises:
administering to the larvae an effective growth inhibiting amount of a compound selected from the group consisting of
(a) compounds of the structure ##STR28## wherein R is hydrogen, lower alkyl containing from 1 to 6 carbon atoms or lower alkoxy containing from 1 to 6 carbon atoms, and
(b) compounds of the structure ##STR29##

### Claim 7 (depends on 6)

The method of claim 6 wherein said compound is 2,4-bis(1,1-dimethylethyl)-6-(phenylmethyl)methoxybenzene.

### Claim 8 (depends on 6)

The method of claim 6 wherein said compound is 2,4-bis(1,1-dimethylethyl)-6-[(4-methoxyphenyl)methyl]methoxybenzene.

### Claim 9 (depends on 6)

The method of claim 6 wherein said compound is 2,4-bis-(1,1-dimethylethyl)-6-(3-phenyl-2-propenyl)methoxybenzene.
