Atrazine (2-chloro-4-ethylamino-6isopropylamino-1,3,5-triazine) is an organochlorine herbicide used commonly in the United States. Adult exposure to atrazine has been linked with hyperglycemia in rats ad fish, and gestational diabetes in humans.
Flies exposed to atrazine throught development show gluose and trehalose levels increased to diabetic levels in hemolymph and tissue samples, along with increased free fatty acid levels. Atrazine exposure causes insulin resistance, as seen by dysregulation of genes including InR, foxo, and insulin-like peptides (gene group: FBgg0000048) in a manner consistent with models of noninsulin-dependent type 2 diabetes (FBhh0000153). Atrazine-exposed flies also show increased oxidative stress, which can be mitigated by overexpressing Sod2.
Exposure to dichlorvos (DDVP), has been found to cause a diabetes mellitus type 1-like phenotype in flies, see FBhh0001137.

Drosophila reared on chronic high sugar diet are hyperglycemic, insulin-resistant with higher levels of triglycerides as well as free fatty acids and obese, which are typical features of type 2 diabetes. (Gupta et al. 2019 and references therein, FBrf0243289.)
