The silver leaf or sweet potato white fly (aka- tobacco whitefly or cotton whitefly) was found to carry Rickettsia (spotted fever) and three other agents in the sample used in this study linked below.
These pests have a wide host range, occurring on more than 500 plant species assignable to over 60 plant families.
Members of the B. tabaci complex have become key pests of a number of agricultural systems throughout the world.
Many predators attack the whitefly, including Anthocoridae, Miridae, Coccinellidae, Neuroptera, various flies, ants, spiders and mites.
Speculation/Question...
If a plant or its fruit (tomato, etc.) is infested with white flies before going to market, or a predator (animal or human) eats the white flies, can the diseases (bacteria, viruses, etc.) be transmitted to those doing the eating?
Could then a spider, or a mite, or an ant transmit spotted fever if it bites you?
Just something to consider and creep you out on an otherwise lovely evening.

Yes, Absolutely, you can get "tick-borne" infections from the bite of infected spiders, ants, mites, etc!
I know a man in my area that was bitten by an ant at a family reunion (need an excuse not to go to the next one.....?) and got a bulls-eye rash the exact spot of the ant-bite 3 days later and a fever. It took him a couple years to get well again.
Also, recorded in the New England Journal of Medicine, a case FROM 1990 of a man bitten by a biting fly (deer or horse fly) while out jogging that came down with Lyme Disease through that bite.
Detection of Lyme disease and anaplasmosis pathogens via PCR in Pennsylvania deer ked M. Buss L. Case B. Kearney C. Coleman J.D. Henning First published: 17 November 2016
ABSTRACT
"Borrelia burgdorferi and Anaplasma phagocytophilum are obligate intracellular parasites that maintain their life cycles in enzoonotic vector‐host cycles with Ixodes scapularis as a vector. In addition to ticks, the hosts are commonly infested with insects from the Hippoboscidae family. This study confirms the presence of B. burgdorferi and A. phagocytophilum in deer keds (Lipoptena cervi) removed from white‐tailed deer using PCR. Detection of these pathogens in deer ked represents a potential novel susceptibility of wildlife and also suggests the risk of transmission of these pathogens to humans and animals alike through the bite of an infected ectoparasite. This study represents the first instance in the U.S. of detection of tick‐borne pathogens in a member of the Hippoboscid family."
As for getting infected via accidentally eating an infected white fly hidden on a vegetable or fruit, I think that would be nearly impossible. Actually, it would be more likely that person would develop immunity to whatever pathogens were harbored in the fly. The gut is the gateway to the immune system and is where many antibodies are formed. 70% of the immune system is (developed) in the gut.
I wouldn't recommend eating ticks though, ha ha! Especially not engorged ones!
