Abstract
Abstract A formulation for use in the biological control of insects, particularly insect pests, comprises an oil suspension of the infective stage of nematodes such as Neoaplectana carpocapsae parasitic to the larvae of those insects. The formulation may be distributed in the form of droplets or films of oil containing this infective stage of the nematodes. Also disclosed is a method and assemblage for rearing nematodes.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
69 words
A formulation for use in the biological control of insects, comprising mineral oil as a suspension medium containing an insecticidal amount of a larval stage of nematodes infective and parasitic to the larvae of said insects and a wax or wax-like material in an amount effective to reduce water loss from said formulation, said formulation substantially not containing any free water but retaining the body moisture of said nematodes.
Claim 2
Dependent Claim
69 words
A formulation for use in the biological control of insects, comprising mineral oil as a suspension medium containing an insecticidal amount of a larval stage of nematodes infective and parasitic to the larvae of said insects and a wax or wax-like material in an amount effective to reduce water loss from said formulation, said formulation substantially not containing any free water but retaining the body moisture of said nematodes.
Claim 3
Dependent Claim
15 words
A formulation according to claim 1 in which the oil is a light mineral oil.
Claim 4
Dependent Claim
19 words
A formulation according to claim 2 in which the oil has an S.A.E. viscosity rating in the range 50-250.
Claim 5
Dependent Claim
14 words

Claim 7
Dependent Claim
20 words
A formulation according to claim 5 in which the paraffin wax has a melting point in the range 135°-145° F.
Claim 8
Dependent Claim
20 words
A formulation according to claim 4 in which the weight of paraffin wax is 5-15% by weight of the oil.
Claim 9
Dependent Claim
20 words
A formulation according to claim 7 in which the weight of paraffin wax is 6-8% by weight of the oil.
Claim 10
Dependent Claim
13 words
A formulation according to claim 1 in which the nematodes are Neoaplectana carpocapsae.
Claim 11
Dependent Claim
32 words
A formulation according to claim 1 wherein said wax or wax-like material is selected from the group consisting of paraffin wax, petroleum jelly, wool wax, wool grease, microcrystalline wax and match wax.
Claim 12
Dependent Claim
112 words
In a method for the biological control of insects using the larval stage of nematodes, the improvement to extent the duration of insecticidal activity of a larval stage of nematodes infective and parasitic to the larvae of insects which comprises using said larval stage of nematodes as an oil suspension thereof, said oil suspension comprising an oil as a suspension medium containing an insecticidal amount of the larval stage of nematodes infective and parasitic to the larvae of insects and a wax or wax-like material in an amount effective to reduce water loss from said suspension, said suspension substantially not containing any free water, but retaining the body moisture of said nematodes.
Claim 13
Dependent Claim
112 words
In a method for the biological control of insects using the larval stage of nematodes, the improvement to extent the duration of insecticidal activity of a larval stage of nematodes infective and parasitic to the larvae of insects which comprises using said larval stage of nematodes as an oil suspension thereof, said oil suspension comprising an oil as a suspension medium containing an insecticidal amount of the larval stage of nematodes infective and parasitic to the larvae of insects and a wax or wax-like material in an amount effective to reduce water loss from said suspension, said suspension substantially not containing any free water, but retaining the body moisture of said nematodes.
Claim 14
Dependent Claim
13 words
The method of claim 11 wherein the oil is a light mineral oil.
Claim 15
Dependent Claim
18 words
The method of claim 12 wherein the oil has an SAE viscosity rating in the range of 50-250.
Claim 16
Dependent Claim
11 words
The method of claim 11 wherein the wax is paraffin wax.
Claim 17
Dependent Claim
21 words
The method according to claim 14 in which the paraffin wax has a melting point in the range of 115°-145° F.
Claim 18
Dependent Claim

Claim 21
Dependent Claim
12 words
The method according to claim 11 wherein the nematodes are Neoaplectana carpocapsae.
Claim 22
Dependent Claim
31 words
The method of claim 11 wherein said wax or wax-like material is selected from the group consisting of paraffin wax, petroleum jelly, wool wax, wool grease, microcrystalline wax and match wax.
