Thermal requirements for development of aphidophagous Coccinellidae (Coleoptera), Chrysopidae, Hemerobiidae (Neuroptera), and Syrphidae (Diptera): some general trends
This is perhaps the first report on the functional relationship between LDT and SET at the interspecific level and reflected thermal adaptations consistent with the life history of the species.
Effect of temperature on development rate and intrinsic rate of increase of Aphis gossypii reared on greenhouse cucumbers
The nearly constant r m in terms of day‐degrees, over a wide range of temperatures, greatly simplifies the prediction of future population numbers of A. gossypii.
Effect of azadirachtin applied systemically through roots of plants on the mortality, development and fecundity of the cabbage aphid (Brevicoryne brassicae)
The mortality of cabbage aphid nymphs, particularly during the period of ecdysis, increased significantly with increasing concentrations and the average longevity of the cabbage aphids decreased with increasing azadirachtin concentration and time spent feeding.
Insecticidal Resistance and Cross-Resistance in Populations of Cydia pomonella (Lepidoptera: Tortricidae) in Central Europe
Two bioassays were used to monitor the resistance of codling moths collected in 2003–2005 in two apple orchards with different intensities of chemical control and no resistance to diflubenzuron was detected in either tested population.
Predictive value of a model of the flight activity of Adoxophyes orana (Lep.: Tortricidae)
In 1992–2002, the flight activity of Adoxophyes orana (AO) was investigated using pheromone traps placed in apple orchards in five localities in Central and Eastern Bohemia using a model constructed using the numbers of AO males caught by pherOMone traps from 1992–1998 at all the localities.
The effect of integrated pest management practices in an apple orchard on Heteroptera community structure and population dynamics
Abstract: The community structure and population dynamics of Heteroptera was studied in an apple orchard in the Czech Republic, between 1992 and 1995. The study investigated the changes which
Laboratory evaluation of the side effects of insecticides on Aphidius colemani (Hymenoptera: Aphidiidae), Aphidoletes aphidimyza (Diptera: Cecidomyiidae), and Neoseiulus cucumeris (Acari: Phytoseidae)
Results showed that both methoxyfenozide and indoxacarb would be suitable for use in the integrated pest management (IPM) because of their low toxic effect against all of the tested model species of natural enemies.
