FIG; ASSAM RUBBER; BANYAN. 



(Ficus spp. Family Urticaceae.) 



This is a very large genus of valuable plants, including the fig {Ficus carica), the 

 India or Assam rubber plant {F. elastica), and the banyan (J**, benghalensis). Many 

 varieties of the fig are prized for their fruit. The India rubber of commerce is derived 

 from F. elastica. Other varieties are popular in conservatories. 



A. BETTER KNOWN FIG INSECTS LIKELY TO BE IMPORTED. 



Slnoxylon sudanlcum Lesne. 



(Fig stem-boring beetle. Bostrychidse; Coleoptera.) 



Host: Fig. 



Injury: Bores in the twigs of young trees. 



Description and biology: Adult beetle, brown with basal half of elytra tinged with 

 yellow, about one-quarter inch long. The apex of the elytra is concave bitubercu- 

 late. The adult bores in twigs near the buds and girdles the twig under the bark, 

 laying its eggs in the outer portion which soon falls to the ground. The species is 

 especially dangerous to niiraery stock just planted, aa it does not usually attack strong 

 healthy trees. 



Distribution: Sudan.
