ABSTRACT

A study was conducted to investigate the occurrence of pests in the ber orchards in Punjab during 2017 and 2018. The infestation of Cadra cautella (Walker) (: ) was observed in ber fruits at the Fruit Research Farm, Punjab Agricultural University, Ludhiana during November-December. About 10% fruits of variety Sanaur were observed to be infested by black coloured larvae making tunnels inside. This is the first report of field infestation by C. cautella on ber fruits from India.

The ber ( Lam.) is one of the bark eating caterpillar, quadrinotata most ancient cultivated fruit of north India.

In India, Platypria erinaceous Weise, Cassida exilis Boheman, ber is cultivated in 50 thousand ha (Anonymous, Oocassida pudibunda Boheman and Glyphocassis 2018), and in Punjab in 1767 ha with yield of 16766 trilineata (Hope); six-spotted flea beetle, Scelodonta kg/ ha and 29626 mt production (Anonymous, 2019). strigicollis (Motschulsky); weevils, Xanthochelus This fruit crop is highly adaptable to adverse climatic faunus (Olivier) and Hypolixus truncatulus F., flower conditions; however, yield losses due to insect pests feeding beetle, Oxycetonia versicolor (F.); chrysomelid do occur.

Ludhiana (30°54’02.8”N, 75°47’34.3”E). Twenty ber trees were randomly observed and the ber fruits were a found to be infested with a fruit borer. Infested fruits were collected and the emerging larvae were reared in the Fruit Entomology Laboratory, Department of Fruit Science, Punjab Agricultural University, Ludhiana, Punjab. The specimens of adults were sent to the National Pusa Collection, Division of Entomology, ICAR-Indian Agricultural Research Institute, New Delhi for identification and it was identified as Cadra cautella (Walker) (Lepidoptera: Pyralidae).

RESULTS AND DISCUSSION

During surveys, C. cautella was observed on ber fruits for the first time in Punjab during 2017 and b 2018. The larvae were observed infesting fruits during November-December. About 10% fruits of variety Sanaur were observed to be infested by black larvae. The larvae were elongated caterpillars feeding on the pulp of fruits and making tunnels through the fruit (Fig. 1a). They feed from the surface of the fruit and continue inside making webs. In case of heavy infestation, the whole fruit from inside was eaten up and damaged while the outer surface had holes of entrance. Fruits get dried, became empty and turn brown. Brownish excreta were observed near the entry hole on the surface of the fruit. Webbing by the borer results in joining of damaged fruits with the leaves (Fig.1b) and joining two fruits with each other (Fig. 1c). Oviposition takes place on the fruits which are c partially dried. Eggs are laid singly on fruits, are whitish, turning to pale yellow near hatching. Eggs take 2-3 days for hatching and newly emerged larva are creamish- white. Head is broader than body and yellowish brown. Larval stage passes through six instars and enters into prepupal stage. Pupae are pale yellow and turn into dark brown before adult emergence. Adults are pale grey while head and thorax are dark grey (Fig. 2, 3). Females are larger in size (Rathod, 1989).

Cadra cautella is also known as dried currant , tropical warehouse moth and fig moth. It is a cosmopolitan and had been observed on dried materials and stored products from tropical and subtropical regions Fig. 1.

The labial palps curved upwards in a front of head with blunt tip. Wing span ranges from 10- 18 mm. Forewings have broadly rounded tips and with short fringes. Forewing with basal coastal fold. Hind- wings whitish with rounded tips and veins visible. Male genitalia dorsal thickenings of the annelus produced posteriorly into triangular trastillae and with broad median lobes (Fig 2b). Female ovipositor short and partially sclerotised on dorsal surface. Ductus bursae with longitudinal sclerite (Fig 2c).

It is serious pest of dried fruits and stored grain products. Damaging stage is the larval stage. Moths are generally more abundant during rainy and humid seasons (Srivastava and Subramanian, 2016). Heavy infestation of C. cautella Male genitalia has been reported on beans, timoriana, a leguminous plant, both in field and in storage at Manipur (Thangjam et al., 2003). This is the only report of its c

field infestation. Field infestation on and b pods continued into stored conditions causing extensive damage in sealed bags. Cadra cautella had been identified as the cause of premature fruit drop inPinus roxburghii during 2014 and 2015 at Manipur, India (Ningombam et al., 2018). This borer is also reported as serious pest on date fruits both in field and in storage conditions in Saudi Arabia (Rees, 2007; Aldawood et al., 2013; Husain et al., 2017). According to Alwaneen et al. (2019), primary infestation of this pest gets initiated in the field when date fruits were still on the trees and continued to storage.
