Ballast tank treatment technologies are currently in development to reduce the risk of acquiring or transporting viable aquatic organisms that could be introduced to ecosystems and become invasive. Aquatic invertebrate resting eggs represent a challenge to such technologies because of morphological and biochemical adaptations to stress that also protect eggs from artificial stressors. To evalua...

The effectiveness of the Metarhizium anisopliae (Metschinkoff) Qu-M845 isolate was evaluated in laboratory and field trials. It was previously selected for thermal resistance (at 30 and 35 oC) and pathogenicity on Varroa destructor (Anderson and Trueman). In the laboratory, the first evaluations were carried out by spraying and increasing the concentration from zero to 108 conidia mL-1 on varro...

Aphids are important pests of crop plants in Europe. Increasing resistance of aphids to insecticides and their side effects on the environment and non target organism's including human's stimulated research on alterative methods of aphid control, including the use of entomotoxic proteins. Lectins are carbohydrate binding proteins that are widely distributed in nature; they have been isolated fr...

Raoiella indica Hirst, 1924 (Prostigmata: Tenuipalpidae), is one of the leading pest mites in palm and banana trees, however, there are few control methods available for this species. Therefore, work aimed to evaluate acaricidal effect soursop seed extract (Annona muricata L.) on R. adults. The experiment was conducted a completely randomized design using with 7 replicates 12 individuals per re...

Vector control is in risk as a result of the advent synthetic pesticide resistance. Plant derived insecticides may be used future bio alternatives due to their target specificity and biodegradability. The aim present study was determine efficacy Chloroform: Methanolic extract Michelia champaca seeds against all larval instars Culex quinquifasciatus, vector Bancroftian filariasis. showed remarka...

The larvicidal efficacy of Calopogonium mucunoides leaf and Chrysophyllum albidum seed extract against 2nd 3rd larval instars Aedes aegypti was investigated in an acute bioassay. bioassay done triplicate ten laboratory-reared larvae Ae. at four different concentrations (250, 500, 750, 1000 ppm) with a simultaneous control 24 h, 48 72 h exposure. Phytochemical screening revealed the presence alk...

Since the discovery of the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in North America in 2000, chemical control has been the most effective method to manage aphid outbreaks. Increased insecticide use in soybean raises the possibility of developing insecticide resistance in soybean aphid, and monitoring insecticide susceptibility is essential to maintain pesticide tools. We...

2-(1-Undecyloxy)-1-ethanol, monochamol, is a male-produced aggregation pheromone of the Monochamus species, which are efficient vectors of the pine wood nematode (PWN), Bursaphelenchus xylophilus, which cause devastating damage to pines worldwide. The nematicidal activity of synthetic monochamol and its homologues (ROEtOH: R = C7-C13) were investigated to find potential alternatives to the curr...

Laboratory bioassay of the essential oil extracted from the grapefruit (Citrus paradisi) peel by steam distillation was carried out against the developmental stages of the yellow fever vector Aedes aegypti to evaluate its toxicity, and ovicidal and larvicidal potency. Volatile oil components isolated and characterized by coupled gas chromatography/mass spectrometry included varying levels of mo...
