Opis:: In this study, the removal of imidacloprid (IMD) pesticide onto activated carbon produced from nut shells of hazelnut (HAC), and walnut (WAC) has been investigated. The prepared activated carbons were characterised by total carbon, nitrogen and hydrogen content, surface areas and pore volume. Fourier-transform infrared (FTIR), and scanning electron microscopy (SEM) were studied before and after adsorption experiments. Effects of adsorbent dose (0.02-0.2 g), contact time (10-120 min), initial imidacloprid concentration (10-100 mg∙dm-3), and pH (1-8), and temperatures (25-50°C) on the removal of IMD pesticide by HAC and WAC in the batch mode were studied. The removal percentage of imidacloprid pesticide by HAC and WAC was 93.79% and 94.72%, respectively. The study showed that the pseudo-second-order kinetics model fitted well for both activated carbons. Moreover, adsorption isotherm results were evaluated using Freundlich, Langmuir and Temkin isotherm models. The adsorption results correlated well with the Langmuir isotherm model (R2 = 0.987 and 0.964) with maximum adsorption capacities of 76.923 and 83.333 mg∙g-1 for HAC and WAC, respectively, and an equilibrium time within 120 min. The nature of the adsorption of imidacloprid pesticide onto HAC and WAC is exothermic, spontaneous and physical in nature. The two prepared activated carbons (HAC, WAC) were successfully regenerated for three cycles and could be used as an effective and low-cost adsorbent for the removal of IMD pesticide from aqueous solutions. The production of the activated carbons of HAC and WAC will provide minimisation of these wastes in the environment.

Opis:: In the laboratory experiment, the effect of neonicotinoid Nuprid 200SC at the dose recommended by the manufacturer on the dynamics of population of earthworms Dendrobaena veneta was assessed. The studies were conducted on mature D. veneta specimens, in 4 replications of beddings (control, insecticide) in the climatic chamber. Condition of the population was checked five times, using a method of manual segregation of beddings. Insecticide limited the increase in number and biomass of D. veneta population (both the whole population, mature specimens and immature earthworms), but also restricted its reproduction (it decreased the number of cocoons laid by earthworms (p<0.05)).

Opis:: The paper present results from the studies carried out in the years 1999-2000 on the effectiveness of seed dressing of spring barley with the insecticide Gaucho 350 FS (a.i. imidachloprid) to control frit flies, gout flies, aphids and thrips in piedmont conditions.
W latach 1999-2000 badano efekty ochrony jęczmienia jarego przed najważniejszymi szkodnikami, uzyskane w wyniku zaprawiania ziarna siewnego preparatem Gaucho 350 FS w dawce 1 I na 100 kg. Stwierdzono: wysoką skuteczność zabiegu w zwalczaniu larw wiosennego pokolenia ploniarki zbożówki uszkadzających źdźbła tego zboża, dość znaczną redukcję populacji mszyc i przylżeńców oraz nieco mniej stabilną w poszczególnych latach (w zależności od przebiegu warunków meteorologicznych oraz ich wpływu na rozwój rośliny uprawnej i populacji szkodników) w zwalczaniu larw wiosennego pokolenia niezmiarki paskowanej uszkadzających dokłosia (a w 2000 r. także zawiązki kłosów) i larw letniego pokolenia ploniarki zbożówki żerujących w ziarniakach. Zaprawianie ziarna siewnego badanym preparatem może być zabiegiem alternatywnym opryskiwania roślin insektycydami w okresie wegetacji. Ta metoda ochrony byłaby szczególnie przydatna w sytuacjach, gdy jęczmień musi być z konieczności wysiewany w terminie opóźnionym (w drugiej połowie kwietnia).

Opis:: The black citrus aphid, Toxoptera aurantii Boyer de Fonscolombe (Hemiptera: Aphididae), an important pest of citrus species, feeds by sucking sap from plant leaves. It causes some leaf distortion and malformation of growing leaves and shoot tips. In this study, the eff ects of the botanical insecticide, palizin on T. aurantii and its parasitoid, Aphidius colemani Viereck (Hymenoptera: Brachonidae) were compared with the chemical insecticide, imidacloprid. Th e compounds were evaluated at maximum recommended fi eld concentrations: palizin 2,000 ppm, imidacloprid 500 ppm, water (as control) on adult aphids. Spraying was done with a 100-l engine Honda sprayer (GX120T1, 160T1, 200T) until run-off . Th e number of dead aphids was recorded 24, 48 and 72 hours aft er treatment. According to the results, statistically signifi cant diff erences were found between treatments (p ≤ 0.05). Twenty-four hours aft er treatment, imidacloprid was more eff ective than palizin in reducing the T. aurantii population. Palizin showed high effi ciency (95% mortality) 72 hours aft er treatment. However, at that time, there was no statistically signifi cant diff erence between the mean mortality percentages of imidacloprid and palizin. This shows that botanical insecticide, palizin can eff ectively control T. aurantii. Also, palizin caused low mortality (10.86%) on A. colemani while imidacloprid was more toxic (31.1% mortality). The results of the present study indicated that palizin can be used instead of chemical insecticide, imidacloprid in control programs of T. aurantii.

Opis:: Efforts have been made during the past three decades to develop insecticides with selective properties that act specifically on biochemical sites present in a particular insect group, but whose properties differ from those present in mammals. This approach has led to the discovery of compounds that affect the hormonal regulation of molting and developmental processes in insects such as ecdysone agonists, juvenile hormone (JH) mimics and chitin synthesis inhibitors. The search for potent acylureas has led to the development of novaluron (Rimon) developed by Makhteshim Chemical Works. The LC-50 value of novaluron on 3rd-instar Spodoptera littoralis fed on treated leaves is approximately 0.1 mg a.i./liter. This value resembles that of chlorfluazuron and is tenfold lower than that of teflubenzuron. Novaluron affects nymphs of Bemisia tabaci more than chlorfluazuron and teflubenzuron. Artificial rain, at a rate of 40 mm/h applied 5 and 24 h after treatment in a cotton field had no appreciable effect on the potency of novaluron on both S. littoralis larvae and B. tabaci nymphs. Hence, novaluron can be used in tropical areas and during rainy seasons. In general, benzoylphenyl ureas had no direct effect on parasitoids and phytoseiids and are considered mildly affect other natural enemies. Novaluron has no cross-resistance with conventional insecticides, the JH mimics pyriproxyfen and neonicotinoids. As such, it is considered an important compound in pest management programs.
