The flowers of different plant species have diverse scents with varied chemical compositions. Hence, every floral scent does not uniformly affect insect feeding preferences. The blowfly, Phormia regina, is a nectar feeder, and when a fly feeds on flower nectar, its olfactory organs, antennae, and maxillary palps are exposed to the scent. Generally, feeding preference is influenced by food flavo...

We present here the first record of plant-insect interactions from an ephemeral volcanic island that was placed 150 km away nearest continental mass. The formed and destroyed during Aalenian (Middle Jurassic) in a shallow sea southwestern Tethyan realm corresponding today to place located eastern Spain. These were mainly documented leaves Cycadophytes (comprising both Cycads Bennettitales), the...

The results of the present experiments provide two lines of evidence consistent with the view that development of olfactory control of feeding-site selection in rats depends on experiences during ontogeny. First, normally reared pups ate at a feeding site at which either an anesthetized conspecific or conspecific excreta were present in preference to a clean site, whereas pups reared without co...

A brief description is given of Perkinsiella saccharicida Kirk. as a pest of sugarcane. Population fluctuations, varietal susceptibility, ovipositional habits, natural control, alternate host plants, alary polymorphism, light attraction and the effect on leafhoppers of trash burning are discussed.

Limited biological information about Phyllophaga ephilida , a major sweet potato pest in Louisiana, is available. In 2001 and 2002, a study was conducted in the laboratory to investigate the feeding preference of adult Phyllophaga ephilida (Say) (Coleoptera: Scarabaeidae) for the foliage of eight woody plant species: water oak ( Quercus nigra L.), live oak ( Quercus virginiana Mill.), red maple...
