## Abstract

A novel Plutella xylostella baculovirus (PxMNPV) which is useful for the control of insect pests has been isolated. A variety of insect pests may be controlled by application of an insecticidally effective amount of the baculovirus to the locus or vicinity of the target insect.

## Claims

### Claim 1

A viral agent comprising a biologically pure Plutella xylostella multiple nuclear polyhedrosis virus having all of the identifying characteristics of ATCC VR-2543.

### Claim 2 (depends on 1)

The viral agent of claim 1 wherein said virus is occluded in an occlusion body.

### Claim 3 (depends on 1)

An insecticidal composition comprising the virus of claim 1 and an agronomically acceptable carrier.

### Claim 4 (depends on 3)

The insecticidal composition of claim 3 wherein said carrier is inert.

### Claim 5

A method for controlling insects comprising applying an insecticidally effective amount of a biologically pure Plutella xylostella multiple nuclear polyhedrosis virus having all of the identifying characteristics of ATCC VR-2543 to the locus of said insects.

### Claim 6 (depends on 5)

The method of claim 5 wherein said insects are of the order Lepidoptera.

### Claim 7 (depends on 6)

The method of claim 6 wherein said insects are selected from the group consisting of Plutella xylostella, Helicoverpa zea, Heliothis subflexa, Heliothis virescens, Trichoplusia ni, Spodoptera frugiperda, and Spodoptera exigua.

### Claim 8 (depends on 6)

The method of claim 6 wherein said insects are selected from the group consisting of Plutella xylostella, Helicoverpa zea, Heliothis virescens, and Spodoptera exigua.
