Aphids have multiple natural predators, which growers rely on to naturally control the aphid population, such as parasitic wasps, Aphidius spp., as well as the seven spotted lady beetle, Coccinella septempunctata. In the fall, the male and female aphids mate and the eggs are laid on buds on the new plant growth where they overwinter until the spring.  Studies have shown that infection can be spread by rubbing viral particles on the leaves of healthy blueberry plants so it is important to immediately remove and dispose of infected plant material once infection has been detected. , The blueberry shoestring virus is vectored by the blueberry aphid, Illinoia pepperi. Oxidative stress increases with high fat meals and with exposure to environmental toxins. Blueberry waffle disease is founded in human of both genders due to various factors.Most of the symptoms and results indicate that blue waffle disease caused by the sexual transmission process. When growing blueberries, it is important to only use certified virus-free planting material. A common symptom that is present in infected plants is elongated reddish streaking on the stems, which is the most common visual diagnostic of BBSSV.

Blueberry shoestring virus (BBSSV) is a disease-causing virus that is commonly transmitted by the aphid vector, Illinoia pepperi. The primary pathogen of concern is a bacteria known as Pseudomonas aeruginosa, which causes a type of soft rot in plants. Some fungi that live on decaying plants can cause disease in humans. If the blueberry industry is to survive, quality controls will have to become a priority to limit the spread of blueberry viruses, especially those that can be transmitted through vectors.. Symptoms vary widely, from urinary tract infections to dermatitis, gastrointestinal … Eating or touching infected plants or their parts would not likely infect us with the same pathogen that is making the plant sick.  During the winter, blueberry aphids overwinter as tiny eggs at the bases of buds. These parasitic predators also attack the aphid eggs. Blueberry shoestring virus, no. The ideal temperature for the eggs to hatch is around 38 °F [3.3 °C]. 2 . The cost of virus diseases is massive in perennial fruit crops such as blueberry and cranberry that require a large initial investment to prepare, plant, and establish fields to the point of maturity and full productivity.

Blueberry benefits have been observed in both short-term (see, for example, references 18, 78, and 100) and long-term human interventions (see, for example, references 76 and 94), which suggests multiple modes of action. When transferring plants from an infected field to a healthy field it is important to wash the plants with water to remove virus-carrying aphids and prevent the spread of the disease to other areas. For more interesting information on this fungus, including a gory picture of infected skin, please see (if you can handle the hard images of diseased skin) http://botit.botany.wisc.edu/toms_fungi/feb2003.html.

Unless the disease is merely a superficial spot (such as sooty blotch and flyspeck on an apple), it may be best to avoid diseased produce. The parasitic wasps lay their eggs inside of aphids and the larvae then consume the aphids from the inside. The information contained within may not be the most current and accurate depending on when it is accessed. They are most commonly found on land that has been recently cleared of native vegetation… Avoid eating moldy or rotten produce, though, as some fungi and bacteria can produce toxic compounds.

In the United States, some ticks carry pathogens that can cause human disease, including: Anaplasmosis is transmitted to humans by tick bites primarily from the blacklegged tick (Ixodes scapularis) in the northeastern and upper midwestern U.S. and the western blacklegged tick (Ixodes pacificus) along the Pacific coast. Diabetes: Blueberry might lower blood sugar levels in people with diabetes. Mycotoxins are generally an issue only on grain, not on common garden produce, and grain for human consumption is well monitored for their presence. Blueberry jam is made from blueberries, sugar, water, and fruit pectin.  The spread of the pathogen towards the south is limited because the vector, I. pepperi, is not found in warm regions since the optimal temperature for blueberry aphid eggs to hatch is around 38 °F [3.3 °C]. 2150 Beardshear Hall Extension Bulletin E-3050.

The disease spreads quickly in a radial pattern and eventually all bushes in a field may become infected. Atherosclerosis is the build-up of plaques in arteries starting as fatty streaks where cholesterol accumulates. P. aeruginosa infections in humans can invade nearly any tissue in the human body, provided they are already weakened. Cancer-Causing Pesticides on Blueberries. Blueberry-fed animals develop fewer plaques in aorta than in controls, and thus reduce the risk of cardiovascular diseases.

Human infection from plants is very rare, but it does happen. Aphids are typically found on the undersides of leaves on the lower succulent shoots. Once a plant is infected, symptoms may take one to two years to develop. Aphid colonies reproduce most quickly on fast-growing young shoots so it is important to avoid over fertilization. There are chances the acidity of the final product may change, resulting in spoilage or increased risk of undesirable conditions that may encourage microorganisms potentially harmful to humans to thrive in this new environment. The blueberry shoestring virus disease is very prominent in highbush and lowbush blueberry plants in the northeastern and upper Midwest of the United States. Blueberry shoestring virus (BBSSV) is a disease-causing virus that is commonly transmitted by the aphid vector, Illinoia pepperi. The fungi, bacteria, viruses, and nematodes that cause disease in plants are very different from those that cause disease in humans and other animals. Aspergillus flavus is a common contaminant of grain and peanuts, and it produces mycotoxins called aflatoxins. For example, people with suppressed or compromised immune systems, taking certain medications or suffering from medical conditions or other causes that may cause the human immune system to be weak (immunosuppressed). Wingless aphids are found early in the growing season while later in the season, the colonies will be made up of both wingless and winged aphids. Virus particles are transmitted primarily through the phloem, but research by Urban et al has shown that the virus is able to travel through the xylem, in the form of plant sap, and it is found in all plant tissues, such as the parenchymatous tissue, as well.

Garden produce from a sick plant is generally safe to eat, although it may not be desirable. Shoestring (Blueberry shoestring virus) Shoestring is a widespread disease of blueberry in Michigan and New Jersey and has also been detected in Washing-ton, Oregon and New Brunswick, Canada. Though, consider that produce from infected plants often has a flavor or texture very different from healthy fruit, so eating it may not be desirable anyway. 2012 Nov. New and Emerging Viruses of Blueberry and Cranberry. In blueberry health research, several important areas remain poorly understood. As a response to crowding in the growing colonies, wings begin to develop on the aphids. However, some plant pathogens may be able to infect humans as well as plants, and those that do tend to be "opportunistic pathogens," especially on a segment of the population at risk. Blueberry-fed animals develop fewer plaques in aorta than in controls, and thus reduce the risk of cardiovascular diseases. This fungus can cause sporotrichosis, also called "rose-picker's disease", if it gets into a person's skin (such as through a scratch) and into the lymph system, or if a person inhales its spores. Can the apples be allowed to mature or should they be removed.
