Virus: Baculoviridae:
Nuclear polyhedrosis virus
NOMENCLATURE:
Approved
name:
Helicoverpo
nucleopolyhedrosis virus
Other names:
(HaNPV).
SOURCE:
The virus occurs naturally in Heliothis
and Helicoverpa species.
PRODUCTION:
The product is produced from the culture
of infected Helicoverpa armigera (Boddie)
larvae under controlled conditions. Polyhedral inclusion bodies are
extracted from the dead insects and formulated as a liquid concentrate.
TARGET
PESTS:
For control of Heliothis
and Helicoverpa species including cotton bollworm (Helicoverpa
armigera), pod borer of pigeonpea and chickpea, borers of tomatoes
and tobacco budworm.
TARGET
CROPS:
Vegetables, pulses, tomatoes and cotton.
BIOLOGICAL
ACTIVITY:
Mode of
action:
As with all insect baculoviruses, HaNPV
must be ingested to exert an effect. Following ingestion, the protective
protein matrices of the polyhedral occlusion bodies (OBs) of the virus are
dissolved within the midgut and the virus particles enter the insect's
haemolymph. These virus particles invade nearly all cell types in the larval
body, where they multiply leading to insect death. Shortly after the death
of the larva, the integument ruptures releasing very large numbers of OBs.

COMMERCIALISATION:

Tradenames:
Heli lure.
APPLICATION:
Apply at a rate of 1,500 billion
occlusion bodies per hectare (750 mis of product per hectare) ensuring good
coverage of the foliage.
PRODUCT
SPECIFICATIONS:
Purity:
The liquid concentrate formulation is
checked to ensure that it is free from human and mammalian bacterial
pathogens.
Storage
conditions:
Store in a tightly closed container in a
cool (<21 °C), dry and dark area. Shelf-life is extended if kept frozen.
Unstable at temperatures above 32 °C.
Shelf-life:
Stable for several weeks if kept cool,
but has great stability if kept in a freezer.
COMPATIBILITY:
Can be used with other insecticides that
do not repel Helicoverpa
and
Heliothis species.
Incompatible with strong oxidisers, acids, bases or chlorinated water.
ENVIRONMENTAL
IMPACT AND NON-TARGET TOXICITY:
HaNPV occurs
widely in nature and there is no evidence of the virus infecting vertebrates
or plants. It has no adverse effects on fish, birds or beneficial organisms.
