Achhireddy N, Singh M, Achhireddy L, Nigg H, Nagy S
J Chem Ecol . 2013 Dec; 11(8):979-88. PMID: 24310323
Phytotoxic compounds obtained from methanol extracts of field-grown lantana (Lantana camara L.) were quantified in terms of their inhibition of ryegrass (Lolium multiflorum Lam.) seed germination and/or seedling growth. Subsequent...

Singh M, Tamma R, Nigg H
J Chem Ecol . 2013 Nov; 15(1):81-9. PMID: 24271428
Aqueous extracts ofLantana camara L. leaves inhibited ryegrass (Lolium multiflorum Lam.) germination and seedling growth. Phytotoxic compounds were fractionated from crude aqueous extracts and fractions were evaluated for their phytotoxicity....

Nigg H, Mallory L, Simpson S, Callaham S, Toth J, Fraser S, et al.
J Chem Ecol . 2013 Nov; 20(3):727-43. PMID: 24242123
Extracts of 22 fruits were tested for their attractancy toAnastrepha suspensa (Loew), the Caribbean fruit fly. Box-orange, calamondin, carambola, cattley guava, loquat, and Surinam-cherry were about equal in attractiveness to...

Nigg H, Stamper J, Easter E, Mahon W, Dejonge J
Arch Environ Contam Toxicol . 2011 Feb; 19(5):635-9. PMID: 21318494
Four airblast applicators of the pesticides dicofol and ethion to Florida citrus were monitored for pesticide exposure with pads placed inside and outside two types of protective coveralls. Hand exposure...

Nigg H, Schumann R, Stuart R, Etxeberria E, Yang J, Fraser S
J Econ Entomol . 2008 Feb; 100(6):1938-44. PMID: 18232414
We were interested in determining the feeding response of the Caribbean fruit fly, Anastrepha suspensa Loew (Diptera: Tephritidae), to various sugar concentrations to develop an improved bait for adults. We...

Hall D, Burns R, Jenkins C, Hibbard K, Harris D, Sivinski J, et al.
J Econ Entomol . 2005 Dec; 98(5):1641-7. PMID: 16334334
Field studies in citrus were conducted to compare the following as attractants for the Caribbean fruit fly, Anastrepha suspensa (Loew): torula yeast-borax; propylene glycol (10%); a two-component lure consisting of...

Nigg H, Schumann R, Yang J, Yang L, Simpson S, Etxeberria E, et al.
J Econ Entomol . 2005 Jan; 97(6):1850-60. PMID: 15666736
We needed a technique to compare the consumption of baits by individual Carribbean fruit fly, Anastrepha suspensa (Loew). By improving consumption and determining individual dose, we could lower pesticide concentration...

J Econ Entomol . 2003 Jul; 96(3):835-43. PMID: 12852624
The purpose of these experiments was to estimate the number and distribution of Diaprepes abbreviatus (L.) neonate larvae dropping from the canopy of infested citrus trees. The number of neonates...
