Detection Of The Phototoxic Dye Phloxine B In Anastrepha Ludens (Loew) (Diptera: Tephritidae), Apis Mellifera Linnaeus (Hymenoptera: Apidae) And Honey, Aleena M. Tarshis Moreno

A spectrophotometric method for detection of phloxine B, a phototoxic dye proposed as a replacement for malathion bait sprays, in extracted tissues of Anastrepha ludens, Apis mellifera and in honey was developed. Dye detection was increased with a pH change from 6 to 13.7 in tissues or from 3.7 to 8 in honey with 2% sodium hydroxide. An LC 50 of 29.62 ppm phloxine B in 30% sucrose was obtained by feeding honey bees. A predictive model for dye in insect tissues and honey was developed and shown to be 89–92% effective. This study provides a forensic approach to determine …
Comparison Of Rodent Communities Of Native Brushland, Replanted, And Secondary Succession Sites In The Lower Rio Grande Valley Of Texas, Mitchell Allen Sternberg
Comparison Of Rodent Communities Of Native Brushland, Replanted, And Secondary Succession Sites In The Lower Rio Grande Valley Of Texas, Mitchell Allen Sternberg
Theses and Dissertations - UTB/UTPA
I compared small mammal communities between mature brushlands, replanted brushlands, and secondary succession sites from November 1998 to December 1999 to evaluate revegetation efforts in the Lower Rio Grande Valley of Texas. I determined rodent community characteristics of the three habitat types. The mature brushland and replanted habitats had similar species diversities and both were significantly higher than the secondary succession habitat. Species diversity was highest at the replanted edge grid during Winter. The current replanting method provides a more diverse rodent community than does natural succession from fallow fields. Wildlife monitoring should be extended to other taxonomic guilds so …
