Diisopropyl methylphosphonate is a chemical by-product resulting from the manufacture of Sarin (GB), a nerve gas that was produced by the Army in the s. A chemical by-product is a chemical that is formed while making another substance. Like other pyrethroids, bifenthrin is chiral; it has different enantiomers which can have different effects. Bifenthrin is found in two enantiomers: 1S-cis-bifenthrin and 1R-cis-bifenthrin. 1S-cis-Bifenthrin is times more toxic to humans than 1R-cis-bifenthrin, while .

The use of herbicides in forests and other agricultural areas has caused concerns about the harm they can do to humans and the environment. Following are suggestions on environmental safety and proper procedures for handling, storing, transporting, and applying herbicides. Although there are references to specific herbicides used in forest management, the information applies. Bobwhite quail, 5-day dietary LC > ppm. Mallard duck, 5-day dietary LC > ppm. Bobwhite quail, Acute oral LC > mg/kg. Honeybee, LD 81 g./bee. This section describes indicator species that were used in toxicity testing and values. Environmental fate. Photolysis: Unstable, half-life less than 1 hour.

Bobwhite quail (Colinus virginianus) that received either 0, 2, 4, or 8 mg/kg methyl parathion (O,O-dimethyl o-p-nitrophenyl phosphorothioate) treatment were investigated as to their susceptibility to predation by a cat (Felis domesticus) hours after receiving methyl parathion (MP), physical activity levels were monitored in quail and included the number of seconds Cited by: The effects of methyl parathion on survivability of wild northern bobwhites (Colinus virginianus) were investigated from to near Tallahassee, Florida.
In three field seasons, bobwhites were administered 0, 2, 4 or 6 mg/kg methyl parathion in corn oil by oral intubation, released and monitored for 14 d using radio telemetry.
Bobwhites receiving 6 mg/kg methyl parathion had lower. Toxicol. Bussiere, J. L., R. Kendall, T. Lacher, and R. Bennett. EFFECT OF METHYL PARATHION ON FOOD DISCRIMINATION IN BOBWHITE QUAIL (Colinus virqinianus).

() The effect of Methyl Parathion on susceptibility of Bobwhite Quail (Colinus virginianus) to domestic cat. ECOLOGICAL EFFECTS Effects on Birds Mecoprop is practically non-toxic to birds. The LC50 is greater than 5, ppm for mallard ducks and 5, ppm for bobwhite quail.
The LD50 (oral) is mg/kg for Japanese quail and mg/kg for bobwhite quail. Effects on Aquatic Organisms Mecoprop is. Oral LD50 values were mg/kg in tests with bobwhite quail. Effects on Aquatic Organisms The concentration in water that is lethal to half of the test organisms (LC50) ranges from mg/l in hour tests with rainbow trout, 46 mg/l in guppies, mg/l in carp and mg/l in goldfish (1, 2).
Treated birds spent more time standing still than untreated birds In addition, quail dosed with sublethal doses of methyl parathion had longer survival under field conditions due to an increase in predation Sublethal Effects.
In doses that do not kill, pesticides cause a myriad of adverse effects on the health of birds. Evidence for hormonal al- terations was obtained in bobwhite quail treated with methyl parathion for 15 d, in which the production of eggs was reduced due to altered secretion of LH, pro- gesterone, and corticosterone (45,46).
Fig. In female bobwhite quail, significant decrease in plasma titers of LH, progesterone and corticosterone (Rattner et al., ) were noted following the short term ingestion of parathion. A variety of pharmacological agents that modify neurotransmitter levels would act at the level of hypothalamus to adversely affect the reproductive functions.

Factors influencing discrimination between insecticide-treated and untreated foods by northern bobwhite. Methomyl was among 24 pesticides tested for interactions with the estrogen receptor (ER) and the androgen receptor (AR) in transactivation assays. Estrogen-like effects on MCF-7 cell proliferation and effects on CYP19 aromatase activity in human placental microsomes were also investigated.

V Two species of quail that have been considered to be the most likely candidates are the northern bobwhite (Colinus virginianus) and the Japanese quail (Coturnix japonica).
Both species are fairly representative of terrestrial birds and are already established models for assessing both acute and reproductive effects of pesticides and other. Meneely GA, Wyttenbach CR.
