“…The majority of the rainfall (76%) is received during South‐West Monsoon, 22% during the North‐East monsoon and the rest during summer season. In India, there is no detailed information on L. pandava infestation in Cycads rather than some preliminary accounts on its presence as a pest of C. beddomei and C. sphaerica (Solomon Raju et al 2009, Rao et al 2015).…”

Luthrodes pandava Horsfield (Lepidoptera: Lycaenidae) has been reported as a pest of cycad plants in the Andaman and Nicobar Islands, India for the first time. Its impact on host species is assessed. Compared to introduced species, endemic cycads appear to be most susceptible to damage by its larvae, feeding on the plant and affecting growth. Larvae damage all above‐ground plant parts. C. dharmrajii L. J. Singh and C. pschannae R.C. Srivast. & L. J. Singh, endemic to the Andaman and Nicobar Islands, are recorded here for the first time as new host plants.

“…It is reported and confined its distribution in Seshachalam hills and Veligondahills of Andhra Pradesh, India. Its conservation status has been assessed variously as Vulnerable (Nayar and Sastry, 1987) and Endangered (Rao et al, 2015). Its population is decreased in natural habitats due to frequent grassfires that effectively block reproductive system.…”

Cycads are the most threatened plants of all living organisms and they are on the brink of extinction in the wild. Cycads need urgent conservation and this can only be accomplished by in situ as well as ex situ conservation techniques. As a consequence of human activity, most of the Indian cycads are threatened with extinction. To oppose the current issues the authors collected three cycad germ plasms from different localities of Andhra Pradesh and carried out a similar kind of germination process. The present study’s intention was to propagate more number of seedlings through seed germination in less time to augment the species population in their natural population. Seed germination response was best by using fleshly outer coat removed cycad seeds (without sarcotesta) while directly collected from trees. The most preferable growing medium is red soil, sand and cocopeat (1:1:1). The seedlings were raised through this method and developed coralloid roots faster which suggests their survivability. The present study provideed a low-cost standard methodology followed for speedy and effective germination and obtained positive results. These methods would help in restoring species in their natural habitats as well as avoiding species extinction in wild.

Cycas beddomeiÂ DyerÂ is known from the Cuddapah, Chittoor, and Nellore districts of Andhra Pradesh. Its habitats are confined to the southern Eastern Ghats in these districts at specified elevations. Issues concerning its identity, typification, distribution, conservation and CITES status are reviewed. Its IUCN red list status is reassessed. The population size of the mature individuals was estimated at 2.05 lakhs; the AOO was 36. 10 sq km (3610 ha) and EOO at 1768 sq km. The species was designated under the â€œEndangeredâ€ category. The species is well adapted to frequent forest fires with its well-established underground stem, a unique feature, not seen in the other cycads.Â
