The braconid wasp, Fopius arisanus (Sonan), a biological control agent for Mediterranean fruit fly, Ceratitis capitata (Wiedemann), was studied in coffee, Coffea arabica L. Fopius arisanus, comprised 79.3% of the total parasitoids (7,014) recovered from fruits collected at three small coffee farms. Data from seasonal host/parasitoid studies at a large coffee plantation also suggested that the m...

Six to nine populations of the diamondback moth, Plutella xylostella (L.), were collected annually from fields of crucifer vegetables in the United States and Mexico from 2001 to 2004 for baseline susceptibility tests and resistance monitoring to spinosad, indoxacarb, and emamectin benzoate. A discriminating concentration for resistance monitoring to indoxacarb and emamectin benzoate was determ...

In a 2-yr study, the impacts of different plastic soil mulches, insecticides, and predator releases on Frankliniella thrips and their natural enemies were investigated in field-grown peppers. Ultraviolet light (UV)-reflective mulch significantly reduced early season abundance of adult thrips compared with standard black plastic mulch. This difference diminished as the growing seasons progressed...

The naturally-derived insecticide spinosad (Conserve SC) was evaluated against larval Culex pipiens L. (Diptera: Culicidae) under laboratory and field conditions in Antalya, Turkey. Laboratory bioassays showed that the 24 h LC50 and LC90 against late 3rd and early 4th instars were estimated at 0.027 and 0.111 parts per million, respectively, while adult emergence was eliminated at concentration...

Localized injection of insecticides into termite galleries in infested wood represents an alternative to whole-structure fumigation for drywood termite control. The efficacy of this method is limited, however, by the use of repellant insecticides and the difficulty of locating drywood termite colonies. The present study addressed both issues by the use of an experimental acoustic emissions (AE)...

In El Alia region damages caused by the date moth Ectomyelois ceratoniae in a citrus grove were reported since 2008. So, this study targeted to monitor pest during three agricultural campaigns and evaluate different treatments control it. The results showed that evolved four five generations according crop year was active from April early December. Besides, lepidoptera reached 50%. Moreover, on...

Spinosad (spinosyn A and spinosyn D), the secondary metabolite produced by Saccharopolyspora spinosa, is a potent insecticide with low effects on environment mammals. Strategies such as metabolic engineering, mutagenesis fermentation process optimization have been employed for its production enhancement. Quantitative real-time polymerase chain reaction(qRT-PCR) one of preferred methods evaluati...

Five new pesticides were evaluated for their effectiveness in the control of Tuta absoluta (Meyrick), (Lepidoptera : Gelechiidae) on tomato plant. The effect of pesticides against egg and larvae were estimated after 2, 5 and 7 days from application. The highest reduction percentage of eggs of Tuta absoluta during two successive seasons achieved by Emacit (81.25 and 74.5) % respectively after 7 ...

The beet armyworm (Spodoptera exigua Hübner) is an important pest of many agricultural crops all over the world. Most of the sugar beet growing regions in Iran are infested. In this study, the acute lethal effects of Pyriproxyfen, Spinosad, and Indoxacarb as well as sublethal effects of Pyriproxyfen on the 1 instar S. exigua were assessed by leaf dip bioassay method. Mortality was recorded 48 h...

Studies were conducted to determine attraction and feeding propensity of oriental fruit fly, Bactrocera dorsalis (Hendel), and melon fly, Bactrocera cucurbitae (Coquillet) to different protein bait mixtures with and without the insecticides spinosad and malathion. The type of protein bait (Provesta621autolyzed yeast extract, MazofermE802, GF-120Fruit Fly Bait, or Nu-LureInsect Bait) had a major...
