Insecticidal activity of fatty acid-rich Turkish bryophyte extracts against Sitophilus granarius (Coleoptera: Curculionidae).
The composition of fatty acids and insecticidal effects was performed for the Turkish mosses Dicranum scoparium, Hypnum cupressiforme, Polytrichastrum formosum, Homalothecium lutescens and the Turkish liverwort Conocephalum conicum. All structures were determined by means of gas chromatography and gas chromatography-mass spectrometry techniques. The determination of fatty acids was done using a...
متن کاملFlight activity of Sitophilus oryzae (L) and Sitophilus zeamais Motsch (Coleoptera: Curculionidae) and its relationship with susceptibility to insecticides.
Insect-pest mobility can influence insect susceptibility to the insecticides used to control them. The objective of this work was to evaluate the flight activity of Sitophilus oryzae (L) and Sitophilus zeamais Motsch populations reared on corn and wheat grains, and its relationship with insecticide susceptibility. Unsexed adult insects with ages between 10 and 20 days were placed on a plastic t...

متن کاملFitness Consequences of Multiple Mating on Female Sitophilus oryzae L. (Coleoptera: Curculionidae)
The effects of multiple mating on Þtness in the rice weevil, Sitophilus oryzae L. (Coleoptera: Curculionidae), were studied. In the Þrst of a series of experiments, the impact of multiple mating on female Þtness was determined by evaluating the effects of a single mating period with one male, continuous exposure to one male, and continuous exposure to Þve males. Continuous exposure to one male ...
متن کاملControl of rice weevil (Sitophilus oryzae L., Coleoptera: Curculionidae) with various formulations of Metarhizium anisopliae
Formulations of Metarhizium anisopliae conidia with oven ash, chalk powder, charcoal and wheat flour at a ratio of 1:4 (W/W) were prepared. Formulations containing charcoal and oven ash had a conidial viability half-life of 4.1–4.3 months at 2071!C. In comparison, unformulated conidia held under the same conditions had a viability half-life of 0.9 month. Bioassays carried out at 2872!C and 7075...
