(fruit and shoot borer) –It is an important and major pest of Brinjal. Farmers in some areas of
Northern India and Bangladesh are finding that even daily applications do not provide effective control. The female moth lays eggs individually on
the shoots of young brinjal plants. The small larvae that emerge soon eat their way into the tender growing shoots where they are protected from
larval parasitoids and natural enemies such as ants and beetles. The feeding activity of the larvae causes the young shoots to droop in a
characteristic manner. As the brinjal plant develops and begins to produce fruit the female moth preferentially lays eggs on the fruit into which
emerging larvae burrow. Several larvae can be present in one fruit at a time, depending of the fruit’s size. As the larvae burrow
into the fruit they block the hole with excrement or frass so preventing predators entering attacking them.
Host plants :
Brinjal and Potato crops.
Brinjal, Potato Mass trapping for control of brinjal borer. The lure is highly attractive to male moths and specific to the target species.
The purpose of this activity is to reduce the chances of female moths finding a mate so that she is unable to produce viable offspring.
Female Leucinodes orbonalis only mate once and from other research we know that even delayed mating can significantly reduce the number of
viable eggs female moths can produce (fecundity).
Crop hygiene :
Crop hygiene is particularly important in areas of intensive cultivation, and in particular where related crops are cultivated over long periods of time.
Infested shoots and fruits should be removed by hand from brinjal fields. Both can act as sources of future infestation. Similarly, at the end of a
woody crop residues are often collected and stored for use as firewood. However, these residues contain larvae which emerge the following spring and
lay eggs in newly established nurseries. Ideally crop residues should be shredded or burnt before the next crop is planted in the same way that fields
are ploughed to reduce populations of soil borne pests and diseases.
ETL for Leucinodes orbonalis is 6-8 No’s of moths per trap per day.
Use 10 No’s Pheromone Traps per acre from 3-4 days crop stage to control pest at early stage.
Install 15 traps per acre if installing at flowering stage.
Trap canopy should be placed one feet above crop canopy to achieve optimum catch.
Recommended trap model:
Phero-Sensor™ - SP or Phero-Sensor™ - BP or Stick-O-Magic™ Water trap.
Recommended for: Brinjal and Potato crops.
