Effectiveness of Sulfuryl Fluoride for Control of Different Life Stages of Stored-Product Psocids (Psocoptera)
DigitalCommons@University of Nebraska - Lincoln, 2012Co-Authors: Athanassiou, Christos G., Phillips, Thomas W., Aikins M. Jamie, Hasan M. Mahbub, Throne, James E.Abstract:With the phase-out and impending ban of methyl bromide, sulfuryl fluoride is among the most promising alternative Fumigant Insecticides for control of stored-product insect pests. It has been evaluated for control of several stored-product insect pests, but there are few data available on its efficacy for control of stored-product psocids (Psocoptera). We evaluated sulfuryl fluoride for control of different life stages of the psocids Liposcelis paeta Pearman, L. entomophila (Enderlein), L. bostrychophila Badonnel, L. decolor Pearman, and Lepinotus reticulatus Enderlein (Trogiidae) in 48-hr trials at 27.5°C. Adults and nymphs were susceptible to sulfuryl fluoride. Complete (100%) adult and nymphal mortality was recorded at concentrations between 4 and 8 g/m3, except for L. decolor for which all adults were only killed at 24 g/m3. Eggs were tolerant to sulfuryl fluoride. Complete egg mortality was achieved at 24 and 72 g/m3 for L. reticulatus and L. decolor, respectively. Survival of L. paeta eggs was recorded even after exposure to 96 g/m3. Given that the highest United States label concentration for sulfuryl fluoride for a 48-h exposure interval is 31.25 g/m3, our study indicates that high doses and/or longer exposures are needed for complete mortality of eggs of L. decolor and L. paeta. Moreover, the present work suggests that there is considerable variation in efficacy of sulfuryl fluoride for control of different psocid species

Terpene ketones as natural Insecticides against Sitophilus zeamais
Elsevier Science, 2015Co-Authors: Herrera, Jimena María, Zunino, María Paula, Dambolena, José Sebastiá, Pizzolitto, Romina Paola, Gañan, Nicolas Alberto, Lucini, Enrique Ivá, Zygadlo, Julio AlbertoAbstract:The eleven terpene ketones, thymoquinone, (R)-carvone, (S)-carvone, pulegone, dihydrocarvone, menthone, verbenone, ocimenone, camphor, α-thujone and piperitenone, were tested as contact and Fumigant Insecticides against adults of Sitophilus zeamais Motschulsky under laboratory conditions. The results show that thymoquinone was found to be more toxic than the other ketones, with lethal doses values being LC50 16.5 μg/cm2 and LC50 13.8 μL/L air (24 h after treatment). These ketones were also subjected to multiple regression analysis and the results derived from the quantitative structure activity relationship (QSAR) model suggested two topological indicators, the Balaban and Randic indices, were the best descriptors of insecticidal activity of the ketones. However, orbital electronegativity of the carbonyl group was the main parameter that connected the inhibition activity of ketones on acetylcholinesterase (AChE). Thus, the insecticidal activity of terpene ketones was primarily explained by the shape of molecules and the branching of the carbon-atom skeleton, while inhibition of activity of AChE was mainly due to the electronic descriptors.Fil: Herrera, Jimena María.
