Journal of Pest Science PubMed  These mealybug species cause damage all over the world in areas with a moist and warm climate. These benefits to the environment from this environmental solution with no costs but a huge increase in crop harvest, obviously is a clear advantage economically to the farmers. Pritchard's mealybug has become a serious pest of African violet, although it also infests Achillea, Arctostaphylos, Geum, and Polygala. (7). It is important for stakeholders to gain access to information and evaluate the firm’s performance before they put. Leptomastix epona is 2-3mm long, with long black antennae, its wings have black stripes. Mealybugs cover the stems and leaf nodes with white and fluffy wax. Biocontrol 61:349–363, Connor DJ, Cock JH, Parra GE (1981) Response of cassava to water shortage. And therefore this leaves the mealybug unprotected from the insecticide. Growth and yield. © 2020 Springer Nature Switzerland AG. Mealybugs, also called "woolly aphids", include many species with a wide range of host plants. Privacy  |  During feeding, the mealybug injects a toxin that causes leaf curling, slowing of shoot growth, and eventual leaf withering. Environmental- An environmental implication is that when the wasps are introduced to south America there was a risk that it could have a huge impact on the food chain as by taking away one organism or gaining one can have a knock on effect on others for example of the wasp was then hunted by a predator this could leave its normal pray to multiply therefore having an over population which in turn can then have knock on effects to their pray and so on and so on until extinction of a food source. There is a parasitic wasp called Anagyrus fusciventris, which can be also introduced against Longtailed Mealybugs but this now requires a release license, as it is not a native parasite to the United Kingdom.

When the cassava plant was introduced to Africa most of its predators for example mites and plant diseases, were not also introduced therefore leaving the plant free of most of its predators but in the 1970’s a pest called the cassava mealybug was accidently introduced from Latin America(2) The pest is a rare insect but it quickly spread across the entire cassava plant growing area and due to the lack of natural predators within 10 years it became the most important pest insect on cassava causing a loss of up 80% of crop. Remember! This time is in early spring as the mealybugs will feed on the foliage and at this point the mealybugs are young and have not had enough time to produce the full thick layer of wax coating. The plant is covered with small, white-to-grey insects with a cottony/wooly covering clustering close to the soil or near the growing tips. Houseplants; Article Sources. The feeding can cause leaves to go yellow and fall off.

The parasitised mealybug becomes swollen and brown in colour, finally becoming "mummified". Field tests were made in randomized plots (six plots) to evaluate six isolates of Heterorhabditis on coffee root for mealybug control.

Male Mealybugs do not feed, so do not cause plant damage. If an infestation cannot be controlled after two or three weekly applications of insecticide, consider destroying the plant before the mealybugs spread to other plants in your home.

Cassava mosaic and mealybug control programs were introduced in the 1970s (2) to combat these two problems, the decline in crop because of the mealybug eating the plant and further decline because of the spread of disease.

Table below shows the disease problem in Arica. This is the effect the cassava mealybug has on the plant resulting in a huge loss of crop due to infested plant crop.
