Leucinodes orbonalis

ByDr. Girish Chandra

 

Leucinides orbonalis

The Brinjal Borer

(Lepidoptera: Pyraustidae)

 

Host: This is a pest of brinjal (Solanum melongena) but also attacks other solanaceous plants. 

 

Damage: Younger larvae bore into the midrib and petiole of the leaf, resulting in drooping of the leaves. Larvae also feed on the tender leaves and flower buds causing dead heart.  Fruits are attacked by making a hole near the basal part and tunnelling inside. Fruit pulp is eaten up.  A single larva can destroy several fruits.

 

Life cycle: Adult moth is whitish in colour with irregular reddish-brown markings on both wings and having a wing span of 1.5-2.0 cm. Longevity of the adults is about a week and fecundity varies between 150 to 250 eggs per female. Eggs, which are whitish and flat, are laid singly on the tender shoots or on fruits and hatch in 3-5 days. Young caterpillars are creamish in colour but full-grown larva is pinkish with brownish head and scattered hairs and warts on its 1.5 cm long body. There are 5 larval instars and the larval period varies between 15 and 25 days. Pupation takes place in a tough greyish to dull brownish elongated cocoon, usually in hidden portions of the plant. Pupal period is 6-8 days. 

 

Distribution: Countrywide distribution in India, Burma, Sri Lanka Congo, Malaysia, South Africa.

 

Control: Damaged shoots and fruits should be removed and burnt. Spray of 0.1% of carbaryl, sevimol, endrin, diazinon, malathion or endosulfan or cypermethrin 0.025% should be timed with egg laying and larval emergence.

            Conservation of the following larval parasitoids brings down population:  Cremastus, Pristomerus, Bracon, Shirakia, Iphiaulax sp.

Identification and Management of Horticultural Pests


Features: Nipa
By (author): A.M. Ranjith

This book has been written, primarily due to my own felt need to have a comprehensive text book on the pests of horticultural crops and methods to manage it, in the integrated way. Due to the widespread use of digital color photography and the good resolution that you get in even the basic level digital cameras, it is possible to get good photos. It was thus more of a need to have a text book to teach the UG and PG students, that this book was written. It was also necessary that any practicing field level worker like officers of the state department of Agriculture and commodity boards, and every practicing farmer with an ability to read English text book, should be guided into the basic facts about the pests of crops. It is most likely that most of the information is available in this book itself, as pest of some other crop. It will then be possible to read on the pest in that , and manage the pest effectively using the latest techniques available to the crop management expert.
