| antimosquito activity of aqueous kernel extract of soapnut sapindus emarginatus: impact on various developmental stages of three vector mosquito species and nontarget aquatic insects. | aqueous (physiological saline) extracts of seed kernel from seven indigenous plants were initially screened for their antimosquito activity against eggs, larvae of all instars, and pupae of aedes aegypti. among various seed kernels tested, the soapnut sapindus emarginatus (sapindaceae) extract was found to exhibit, for the first time, a strong antimosquito activity as evident from its ability to inflict 100% mortality of all the developmental stages of a. aegypti. furthermore, the kernel extract ... | 2009 | 19655173 |
| ontogenetic trajectory and allometry of diplonychus rusticus (fabricius), an oriental aquatic bug (hemiptera: belostomatidae) from the western ghats of india. | despite being one of the dominant groups in freshwater ecosystems, morphological and ontogenetic studies on aquatic hemiptera have received little attention in the oriental region. we present the ontogenetic trajectory and allometry of the widespread oriental belostomatid species, diplonychus rusticus (fabricius) for the first time. we have measured nine different morphological variables throughout the growth of the bug using both field captured and laboratory reared specimens. our results sugge ... | 2017 | 28065803 |
| diversity and community structure of aquatic insects in a pond in midnapore town, west bengal, india. | in total 20 species of aquatic insects have been recorded from a weed infested pond. odonata was numerically the most abundant group constituting of 54% of the total aquatic insects even though these belonged to three species. coleoptera though constituted only 22% of aquatic insects had 10 species. urothemis signata and ranatra filliformes were eudominant and dominant species respectively. hydrometra butlen is recorded from west bengal for the first time. five species of hemiptera, ranatra fili ... | 2009 | 20121032 |
| effect of salinity on the predatory performance of diplonychus rusticus (fabricius). | predatory efficiency of diplonychus rusticus (fabricius) was recorded at different prey density with different salinity ranges. when the salinity level (ppt) was increased, the predation rate of the bug decreased. fifth nymphal stage showed higher predation in the 2, 4 and 6 ppt levels of salinityin both 1 hr and 24 hr period of exposure at prey densities 50, 100, 150 and 200. at prey density 150, adult bugs killed more prey in the 2 ppt level of salinity in both lhr and 24 hr treatments. | 2008 | 18972679 |
