Several substances/food baits and admixtures thereof were tested in a perspex trap, treated with insecticide [email protected] mg/cm2. Bioefficacy for housefly trapping was evaluated. Combination of ingredients was found to be more effective than individual ingredients. A combination of some easily available and cheap ingredients were employed for field trials. The admixtures of milk powder, dog b...

Present paper deals with the synthesis of guanidinopyrimidine derivatives from substituted-biguanides, and with thier biological activities. 2-Arylguanidino-4,6-dimethylpyrimidine derivatives had stronger herbicidal activity than 2-alkylguanidines. Espec ia l ly , 2-phenethylguanidino-4,6_dimethylpyrimidine inhib i ted a lmost the growth of radish roots at the concentration of 50 ppm, while at ...

This paper presents a detailed characterization of the trajectory of a single housefly with free range of a square cage. The trajectory of the fly was recorded and transformed into a time series, which was fully analyzed using an autoregressive model, which describes a stationary time series by a linear regression of prior state values with the white noise. The main discovery was that the fly s...

The fluorescence of housefly photoreceptors was studied in viuo by using the deep pseudopupil technique. Whereas the rhodopsin R490 of the peripheral retinular cells fluoresces negligibly the metarhodopsin M580 fluoresces distinctly in the red. The newly discovered metarhodopsin M’ is produced by intense blue light and can be reconverted into rhodopsin by intense long wavelength light. M’ also ...

The absorption of a photon by a photoreceptor triggers a small voltage fluctuation termed the 'bump'. Here, in the housefly, I introduce the bispectrum of photoreceptor noise to characterise the bump under dim light. The bispectrum provides explicit phase information and is not contaminated by Gaussian background noise. Over the photon rates examined (<10(4) s(-1)), I show that bumps are minimu...

Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) technique has been used in the present study to investigate genetic relationship between the two muscids viz., housefly Musca domestica Linnaeus and Lispe orientalis (Wiedemann). Tools for Population Genetic Analysis (TFPGA) software, was used to calculate genetic identity and distance, using data matrix prepared by the prese...
