Use of a mathematical model to study the dynamics of Ctenocephalides felis populations in the home environment and the impact of various control measures

Parasite, 2004
The biology of fleas has been studied by a number of authors, as has the impact of various types of control measures. However, there are no mathematical models simulating the dynamics of a population of Ctenocephalides felis felis fleas on their host ...

Alkylene-bis-isothiocyanates: Novel Insect Growth Regulators

Zeitschrift für Naturforschung C, 1986
In search for selective anti-insect agents some mono- and bis-isothiocyanates were prepared and tested on third instar larvae of Manduca sexta. The alkylene-bis-isothiocyanates 4, 5 and 6 had a novel effect preventing formation of the abdominal spiracles and of the hooks (crochets) at the following molt to the 4th instar.

Influence of short time exposure to an insect growth regulator, hexaflumuron, on mortality and adult emergence of vector mosquitoes

Memorias do Instituto Oswaldo Cruz, 1992
Hexaflumuron, an insect growth regulator (IGR), was found to greatly affect the development of immatures and emergence of adults of three species of vector mosquitoes, Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi, when larvae were ...

Exposure by nesting material? – Investigation of potentially suitable methods for higher tier studies with solitary bees

Julius-Kühn-Archiv, 2018
The registration processes and risk assessment of plant protection products (PPPs) on bees resulted in an increasing need for experiments with non-apis pollinators to assess potential side effects of PPPs on this relatively new group of test organisms ...

Increased regeneration efficiency of _Brassica napus_ L. cultivars Star, Westar and Cyclone from hypocotyle and cotyledonary explants [PDF]

, 2010
The comparative organogenesis of _Brassica napus_ L cultivars Cyclone, Star and Westar was studied. The cotyledonary explants gave a higher response to all the combinations of 0.5 mg/L 2,4-D and BAP (0.5, 1.0,1.5 and 2.0 mg/L} used for optimizing the ...
