“…The toxicity of coumaphos was additionally found to be within the toxicity range of organophosphates tested on at least one other susceptible arthropod adopting the same methods as those used in this study [6]. The relatively low lethality of amitraz observed in this study was also consistent with general reports that the biological action of amitraz is due more to its sublethal effects, rather than to a direct lethality [5].…”

-We conducted laboratory tests investigating the mortality of mites infesting honey bee colonies in Minnesota after exposure to fluvalinate, amitraz, or coumaphos. Results indicated that these mites were not only resistant to fluvalinate, but also to amitraz. Coumaphos was effective against these resistant mites. A separate field trial was conducted with the same hives as those used in the laboratory test. The field trial supported the laboratory results, showing that mites in Minnesota are resistant to both fluvalinate and amitraz, and that coumaphos is effective in controlling these mites. This represents the first known reported case of amitraz resistance in Varroa jacobsoni in the U.S.A.

“…The intensity and duration of the resistance monitoring program for B. tabaci in the Imperial Valley provided a unique opportunity to observe seasonal variation in insecticide susceptibility. Monitoring programs carried out for other pest species have focused primarily on susceptibility in a single crop, often in cotton due to traditionally heavy reliance upon chemical control for managing cotton pests (Dennehy & Granett, 1984;Forrester et al, 1993;Kanga et al, 1995). The outbreak conditions in the Imperial Valley that persisted through the mid-1990s enabled collection of B. tabaci populations from three principal crops that altogether spanned the calendar year.…”

A resistance monitoring program conducted for the polyphagous whitefly, Bemisia tabaci (Gennadius), in Imperial Valley, CA, USA generated a large set of LC50s for adults collected from broccoli, cantaloupe and cotton crops over a four-year period. A vial bioassay and, subsequently, a yellow-sticky card bioassay produced similar temporal profiles of relative susceptibilities to the pyrethroid insecticide bifenthrin. Both bioassays revealed that whiteflies collected from broccoli were significantly less susceptible to bifenthrin compared to the other two crops. A similar finding was observed for endosulfan and the mixture of bifenthrin+endosulfan in the yellow-sticky card bioassay. The possibility that seasonal differences contributed to the observed differences in susceptibility provided the impetus to conduct a reciprocal transfer experiment using broccoli (or kale) and cantaloupe grown simultaneously in the field and greenhouse. Whitefly adults collected from an organic farm over three consecutive weeks had significantly higher LC50s on kale than those collected the same day on cantaloupe. After culturing in the greenhouse on broccoli or cantaloupe and testing again, LC50s remained significantly higher on broccoli after one week and again at the F1 generation. In contrast, whiteflies originating on kale in the field and transferred to cantaloupes in the greenhouse had significantly reduced LC50s at the F1 generation. When tested against the bifenthrin+endosulfan mixture, significantly higher LC50s were generated for whiteflies reared on broccoli in the greenhouse at one week and the F1 compared to the field source from cantaloupes. The consistently higher LC50s for whiteflies on broccoli and other Brassica spp. crops, compared to cantaloupes or cotton, point to statistically significant host-plant influences that are expressed in both field-collected and greenhouse-reared populations of whiteflies.
