eucalyptus species are cultivated in homogeneous plantations in brazil, mainly to supply woodfor the cellulose and steel industries, which favors the establishment of insect pests. the objective was todetermine the geographical distribution and structure abundance of lepidoptera defoliators of eucalypt.primary pest species of eucalypt of the order lepidoptera were found in all areas sampled and...

In the February 1992 issue of the American Mathematical Monthly, J. E. Connett [1] asked whether it is possible to construct a 'light trap': a re ective-sided container with the property that a beam of light, shone into it from an appropriate direction, would be re ected inside it over and over again and never escape. Connett suggests that such a trap might be of value as a device to store ligh...

Centers For Disease Control and Prevention (CDC) light traps were modified for use with light-emitting diodes (LED) and compared against a control trap (incandescent light) to determine the effectiveness of blue, green, and red lights against standard incandescent light routinely used for sand fly surveillance. Light traps were baited with dry ice and rotated through a 4 x 4 Latin square design...

West Nile virus surveillance was conducted at five sites in New Castle County, DE, and one site in Salem County, NJ, from June through September, 2004, using dry ice-baited Centers for Disease Control miniature light traps, infusion-baited gravid traps, and resting boxes. All trap types were simultaneously placed at each site every two weeks and run overnight. Collected mosquitoes were identifi...

Traps that use ultraviolet light as an attractant for flies are widely used in urban situations. To determine the differences in trap efficacy from design and lighting, pairs of traps were compared under laboratory conditions. Comparisons were made between traps with open fronts and with traps with restricted open fronts, black light bulbs, and black light blue bulbs, and glue boards with and w...

The effectiveness of CO2-baited Centers for Disease Control and Prevention miniature light traps elevated in the tree canopy (approximately 7.6 m) was compared with light traps placed at ground level (approximately1.5 m) and grass-sod infused gravid traps for collecting Culex pipiens, Culex restuans, and Culex salinarius and detecting West Nile virus (WNV) activity in an operational surveillanc...

We conducted two experiments to determine the best CDC-trap configuration for catching male and female Phlebotomus papatasi. First, visual features were evaluated. Standard CDC traps were modified to have black or white catch bags, black or white lids, or no lids and these were tried in different combinations. Significantly more male sand flies were caught by darker traps; significantly more fe...

during a faunistic study of the family carabidae in guilan province in summer 2011, beetle specimens were collected directly or by using pitfall traps and light traps. a species of ground beetles was identified and later confirmed by dr. r. felix (berkel enschot, the netherlands) as parophonus dia (reitter). this species is recorded from iran for the first time.
