Abamectin, a natural product pesticide that degrades rapidly in air and sunlight, has been encapsulated with the protein zein. The result was a mineral oil suspension that included a photostabilized abamectin. After exposure to simulated sunlight, th

Avermectins are a family of 16-membered macrocyclic lactone natural product homologues produced by the soil microorganism Streptomyces avermitilis MA-4680 (NRRL 8165). These compounds are closely related to the milbemycins, another family of 16-membe

The avermectins are a family of macrocyclic lactones, produced by the soil organism Streptomyces avermitilis, which were discovered in the mid-1970's as a direct result of a screening effort for natural products with anthelmintic properties. Avermect

The translaminar activity of avermectin B1 (AVMB1; 1.8% wt/vol EC) against second instars of a susceptible laboratory strain of Plutella xylostella L. varied considerably with crop species; the LC50 for AVMB1 was about 145 and 250 times lower on Chin

Avermectin B, (AVMB,) is a relatively slow-acting (96 h) pesticide whose activity appears to be independent of temperature (15-25°C). By topical application, AVMB, was more toxic than cypermethrin, malathion, or DDT against a standard susceptible la

SUMMARY Avermectins (AVM) B1a/1b and B2a-23-one rapidly impaired the locomotor activity of Meioidogyne incognita second stage juveniles. On agar plates, concentrations as low as 0–0003 μg AVM B2a-23-one cm-3 significantly reduced the number of juv
