Sublethal doses of thiamethoxam metabolite clothianidin ( 0.05 2 ng / bee ) have been known to cause reduced foraging activity since at least 1999, but this was quantified in 2012 by RFID tagged honeybees.

More people are likely to be exposed to sublethal doses of radiation while cleaning up or standing guard at the site of a radioactive attack than might be exposed to lethal doses in the attack itself, he said.

Large infestations are sometimes controlled by the spray-graze method, in which plants are sprayed with a sublethal dose of hormone herbicide to make them more palatable to stock, and the area is heavily grazed three days later.

The baits have to contain sufficient amount of zinc phosphide in sufficiently attractive food in order to kill rodents in a single serving; a sublethal dose may cause aversion towards zinc-phosphide baits encountered by surviving rodents in the future.

It was suggested that " while exposure to many of these neurotoxicants elicits acute and sublethal reductions in honey bee fitness, the effects of these materials in combinations and their direct association with CCD or declining bee health remains to be determined ."

In one study, the exposure of rats to sublethal amounts of carbofuran decreased testosterone by 88 %, while the levels of progesterone, cortisol, and estradiol were significantly increased ( 1279 %, 202 %, and 150 %, respectively ).

Dr . Eugene P . Cronkite, an expert in radiation biology who was among the first to recognize and report on links between cancer and exposure to sublethal levels of radiation, died on June 23 at his home in Setauket, N . Y . He was 86.

A 2012 " in situ " study provided strong evidence that exposure to sublethal levels of imidacloprid in high fructose corn syrup ( HFCS ) used to feed honey bees when forage is not available causes bees to exhibit symptoms consistent to CCD 23 weeks post imidacloprid dosing.
39.
In 2012, researchers announced findings that sublethal exposure to imidacloprid rendered honey bees significantly more susceptible to infection by the fungus " Nosema ", thereby suggesting a potential link to CCD, given that " Nosema " is increasingly considered to contribute to CCD.

A 2012 " in situ " study provided strong evidence that exposure to sublethal levels of imidacloprid in high fructose corn syrup ( HFCS ) used to feed honey bees when forage is not available causes bees to exhibit symptoms consistent to CCD 23 weeks after imidacloprid dosing.
