Juglans Australis
''Juglans australis'', the nogal criollo, is a species of plant in the Juglandaceae family. This large, fast-growing tree can grow to tall at elevations of 0.5—1.5 km in the Southern Andean Yungas, montane cloud forests on the eastern slopes of the Andes in Tucumán, Salta, and Jujuy provinces of Argentina and Tarija and Chuquisaca departments of Bolivia. It is threatened by habitat loss. Description ''J. australis'' is a spreading deciduous tree, up to 25 m. wide which produces first quality lumber, with a straight trunk up to 6 m. tall and up to 5 dm. in diameter. The wood is dense (640 kg/m3), hard, and strong. Upon drying, the radial shrinkage is 2.2%, the tangential 4.7%. The pinnately compound leaves are borne alternately, and bear up to fifteen oval-lanceolate finely serrate leaflets. Like most walnuts, ''J. australis'' produces juglone, an allelopathic substance which decreases competition from other plants growing nearby. It is more fro ...

Anastrepha Schultzi
''Anastrepha'' is the most diverse genus in the American tropics and subtropics. Currently, it comprises more than 300 described species, including nine major pest species, such as the Mexican fruit fly (''A. ludens''), the South American fruit fly (''A. fraterculus'' complex), the West Indian fruit fly ('' A. obliqua''), the sapote fruit fly (''A. serpentina''), the Caribbean fruit fly (''A. suspensa''), the American guava fruit fly (''A. striata''), and the pumpkin fruit fly ('' A. grandis''), as well as the papaya fruit fly (formerly ''Toxotrypana curvicada'' and ''T. littoralis''). As some of their names suggest, these pest species are one of the most numerous and damaging groups of insects in their native range, plaguing commercial fruits such as citrus, mango, guava, and papaya. Biology and ecology Natural history and life cycle Females lay their eggs in either developing and healthy fruits or in mature and rotten fruit (like the '' A. suspensa)''. The vast majority of ...
