Veech (7) reported that dif lubenzuron had ovicidal activity against Meloidogyne incognita and suggested that this activity could be impor tan t in developing new control strategies. Radewald et al. (5) and Birchfield (1) respectively provided prel iminary evidence that oxamyl suppresses reproduct ion of M. incognita and Rotylenchulus reniformis. This study was conducted to determine the effect...

(1) Background: The tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae) is a key tomato insect pest. At present, it is considered to be a serious threat in various countries in Europe, North Africa, and Middle East. The extensive use and the developed resistance of T. absoluta to spinosad causes some concern, which leads to the need for alternative products. (2) Materials and Methods: Sev...

The effectiveness of spinosad for larval mosquito control is summarized based on available published literature and some heretofore unpublished studies. Spinosad is highly active against larvae of all mosquito species tested thus far. It is effective at similar dosages for all larval mosquito instars, with peak cumulative mortality occurring at 72 h posttreatment. More studies are needed to ful...

We report that methoprene and its derivatives can stimulate gene transcription in vertebrates by acting through the retinoic acid-responsive transcription factors, the retinoid X receptors (RXRs). Methoprene is an insect growth regulator in domestic and agricultural use as a pesticide. At least one metabolite of methoprene, methoprene acid, directly binds to RXR and is a transcriptional activat...

To evaluate the effects of pesticides to parasite eggs, Ascaris suum eggs were incubated with 5 different pesticides (1:1,500-1:2,000 dilutions of 2% emamectin benzoate, 5% spinetoram, 5% indoxacarb, 1% deltamethrin, and 5% flufenoxuron; all v/v) at 20℃ for 6 weeks, and microscopically evaluated the egg survival and development on a weekly basis. The survival rate of A. suum eggs incubated in n...

One of the main pests on rice plants difficult to control is Leptocorisa acuta . This has a distinctive odor and attacks in generative phase. L. by sucking grains at milk stage so that become empty quality reduced. High attack intensity will cause decrease production. The most widely used method controlling these use synthetic insecticides. insecticides among farmers tends be excessive damage e...
