Levels of mRNA for the two 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthases, (HMG-S1 and HMG-S2), and for HMG-CoA reductase (HMG-R) of Blattella germanica were analyzed in the fat body during the first gonadotrophic cycle. HMG-S2 and HMG-R showed the highest mRNA levels on day 0 and decreased thereafter, whereas HMG-S1, showed faint expression. Western blot using specific antibodies fo...

The study of the insect distribution in geographical areas is relevant since it important terms understanding global trend biodiversity decline. paper presents results a on six species Panorpidae (Mecoptera), carried out 2008, 2009, 2011, 2015, 2017–2020. One part data was collected by authors. Other material provided colleagues from 11 regions Russia. In European Russia, Panorpa are reliably k...

Cockroaches were collected from hospitals, houses and poultry sheds in various parts of Isfahan (Iran) and identified to species. In total, seven species of cockroaches in seven genera were identified: Blatta lateralis, Polyphaga aegyptiaca, Arenivaga roseni and Parcoblatta spp. Three species Periplaneta americana, Blattella germanica and Supella longipalpa (Blattidae and Blattellidae) were mor...

The molluscicidal activity of leaf and rhizome extracts of Iris germanica L. (var. alba) against Biomphalaria alexandrina snails was evaluated and the rhizome extracts were found to be the most potent. Activity-guided fractionation revealed that the chloroform extract showed the highest molluscicidal activity (LC90 = 1.26 mg/l) among the tested extracts of the rhizomes. Fraction B prepared from...

Background and objectives: The serum glucose lowering, normalization animal body weight and antioxidative stress effects of Mespilus germanica L. leaf extract were investigated in normal and streptozotocin-induced Balb/C mices. Methods: The leaves of M. germanica were extracted using acetone/water (70:30) by percolation method and concentrated...

The European wasp, Vespula germanica (Fabricius) (Hymenoptera: Vespidae), is of Palaearctic origin, being native to Europe, northern Africa and Asia, and introduced into North America, Chile, Argentina, Iceland, Ascension Island, South Africa, Australia and New Zealand. Due to its polyphagous nature and scavenging behaviour, V. germanica threatens agriculture and silviculture, and negatively af...

this study was designed to evaluate the efficacy of beta-cyfluthrin (responsar 12.5% sc), against a standard susceptible strain of german cockroach, blattella germanica, using three different dosages, at three different exposure times, on two types of surface, parlous (mosaic) and non parous (glassed ceramic of tiles). comparison of the resifts indicated that beta-cyfluthrin at 12.5 a.i.mg/m2, ...
