Transmission
Marek’s is highly contagious and spreads by bird-to-bird contact, by contact with infected dust and dander, and by darkling beetles and mealworms that live in the chicken house, although the virus has no affect on the beetles or mealworms.
Meal Worms may carry Mareks disease and a bunch of other unwanted guests, (still trying to figure out mealworm types, not an easy lookup)
Chickens can also be exposed to Mareks virus by direct contact with ill or carrier chickens - which includes almost all chickens. Wild pheasant, quail and turkeys can pass the disease to free range chickens. One other route of infection is through meal worms, (which many small flock owners feed) and the darkling beetles that are the adult mealworm form. The mealworms do not become sick from Mareks.http://www.examiner.com/article/how-to-prevent-losses-from-mareks-disease-michigans-small-chicken-flocks
Darkling beetles or lesser mealworms (Alphitobius diaperinus)Disease transmission
Darkling beetles are known vectors and reservoirs for a number of serious poultry disease agents
(leucosis, Marek’s disease, infectious bursal disease, reovirus, enterovirus, fowl pox and Newcastle
disease) and can act as intermediate hosts for caecal nematodes, tapeworms and protozoa. In addition,
they can transmit a number of food-borne diseases such as Escherichia coli andSalmonella typhimurium,
and have been recently implicated in the transmission of Campylobacter.http://www.poultryhub.org/wp-content/uploads/2012/06/Darkling_Beetles_web.pd
