The symptoms of wilt disease and the geographic distribution of the pineapple mealybug complex are described. Apparently, the orchid mealybug is the most problematic species in California, particularly in greenhouses. Pineapple mealybug, Dysmicoccus brevipes. Commercial growers who need to control the Long-tailed mealybug should consult their professional organisation for up-to-date advice. Pseudococcidae (Insecta: Hemiptera). The adult male does not have a rostrum or stylets and does not feed. A third species, Pseudococcus longispinus (Targioni-Tozzetti) induces wilt symptoms in … Common examples include the longtailed mealybug (Pseudococcus longispinus), which has characteristically long waxy filaments that protrude from the end of the abdomen, and the obscure mealybug (Pseudococcus viburni), which also has waxy filaments, but they are much shorter in comparison to the longtailed mealybug. To the human eye this makes it much easier to find the colonies of mealybugs. plant-synz.landcareresearch.co.nz/. Entomophaga, 25(4):415-426. J. It is a solitary, internal parasitoid and lays one egg per host, with the larva developing inside the host’s body. No pathogens of the Long-tailed mealybug, Pseudococcus longispinus, are known in New Zealand. Cox JM. The pink strain reproduced parthenogenetically, while the gray strain reproduced sexually. are working on the identification of the female produced sex pheromone of the pineapple mealybug [ Dysmicoccus brevipes (Cockerell), Homoptera: Pseudococcidae], which is a pest infesting pineapples in Okinawa.6 Dr. Tabata asked me to synthesize samples with the proposed structure 1 of the pheromone (Tabata, J. personal communication). Presumably, the virus is carried on or near the stylets of the mealybug.

The mealybug is also a pest of pears, and to a lesser extent, apples in South Africa (Swart, 1977). At the posterior end of the body are two pairs of much longer white wax filaments. It mainly lives on the underside of leaves, but it can be found on all parts of a plant including under bark. Mealybugs have a short white wax anal tube through which they excrete the excess sugary liquid, which is called honeydew. Saccharicoccus sacchari (Cockerell) (Sugarcane mealybug). They may occur singly or in dense colonies. In laboratory studies, Anagyrus pseudococci were reared on Pseudococcus longispinus, Pseudococcus calceolariae (Maskell), Planococcus ficus, Pseudococcus njalensis Laing, Dysmicoccus brevipes, and Pseudococcus affinis (Maskell) Longtailed mealy bug, Preudococcus longispinus (Targioni-Tozzetti), life cycle. The second instar male makes a fluffy white cocoon in which develop two pre-adult non-feeding stages, a prepupa and a pupa. The ants and natural enemies associated with mealybugs on pineapple are reviewed as part of a discussion of the role of ants in promoting mealybug infestations. The male may mate with females of the same colony or fly to another colony to mate. The history of the discovery of the disease, the disease etiology, the association of mealybugs with wilt, and the mutualism between ants and mealybugs on pineapple are discussed in detail. They are pale brown or purple under the wax. Like many other mealybugs the long-tailed mealybug is covered by white wax. Finally, management techniques for wilt, including ant and mealybug control, are reviewed. ... Coccus viridis, Phenacoccus madeirensis, Pseudococcus jackbeardsleyi, and Pseudococcus longispinus. When it wishes to feed, the mealybug moves the tip of the rostrum onto the surface of the plant leaf or stem. It goes after pineapples, citrus, coffee, cotton, and many Ananas-species trees (including bananas). Two species of mealy- bugs, Dysmicoccus brevipes (Cockerell) and D. neobrevipes Beardsley, are associated with wilt disease of pineapple under field conditions.

In Hawaii the longtailed and pineapple mealybugs are common on orchids. 2019. By this time the genus had b… Results obtained showed that PMWaV-2 is transmitted by the grey pineapple mealybug in a semi-persistent manner. This suggests to me that it may be some kind of deterrent and warning. The Long-tailed mealybug, lives on ferns, herbacious plants, shrubs, trees and climbers. Home gardeners who wish to control the Long-tailed mealybug should ask their local garden centre or horticultural supplier about the available options. Attia, A.R. Proc Hawaiian Entomol Soc 36:9-28. (Pseudococcus longispinus), Jack Beardsley mealybug (Pseudococcus jackbeardsleyi), orchid mealybug (Pseudococcus microcirculus) and the obscure mealybug (Pseudococcus viburni). The young mealybugs often settle by against something prominent on the plant. The red bodied male grows a pair of long white wax tails. A review of the association of ants with mealybug wilt disease of pineapple. Other species may have two to four long posterior wax filaments and obvious lateral wax filaments. However, it can easily be recognised because it is the only species in New Zealand where the adult female has both four very long posterior tails and long lateral wax filaments. It lives on a wide variety of cultivated, naturalised and native plants. Dysmicoccus brevipes, ‘Pseudococcus brevipes’, ‘Dactylopius brevipes’, ‘Pineapple mealybug’ One of the lesser-known mealybugs in most of the United States, the pineapple mealybug is a pink or pinkish-orange color.

(= Pseudococcus longispinus (Targioni-Tozzetti)). On the underside of the head there is a short rostrum that guides the feeding stylets. A great deal of data on this subject has been published in the relatively obscure technical papers and reports of the defunct Pineapple Research Institute of Hawaii. Hempel, and the pineapple mealybug, Dysmicoccus brevipes (Cockerell) (Noyes and Hayat 1994). Pineapple heart rot disease incidence was determined as described by Bua et al. They usually do this using the wind. This mealybug gets its common name from the two long, waxy filaments protruding from the last abdominal segment of adult females (Figure 1). Mealybugs are common indoor pests. The time for a generation varies from 1 month in the heat of summer to 4 months during the cold of winter. The closterovirus PMWaV is transmitted by the pink pineapple mealybug Dysmicoccus bre-vipes and the grey pineapple mealybug D. neobrevipes, the second and third instars being more effective at acquiring the virus than first instars and gravid females (Sether et al., 1998). Other insects with a scale stage also cover themselves with white wax. It is likely that some first instar nymphs climb to a prominent place on a leaf or branch and await a gust of wind. When it is ready to emerge from the cocoon, the back end of the cocoon is pushed open and the male backs out.

Pseudococcus longispinus (Targioni Tozzetti) (Long-tailed mealybug). Insufficient mealybug control can lead to whole pineapple plant-ings being lost due to mealybug wilt, result-ing in lost fruit production (Carter, 1933). Hemiptera: Pseudococcidae is the dangerous of pineapple pest in Mediterranean Region. When choosing a pesticide, consider information relating to air and water quality, resistance management, and the pesticide's properties and application timing. The body is covered with powdery white wax and is surrounded by long white wax filaments. Two species of mealybugs, Dysmicoccus brevipes (Cockerell) and D. neobrevipes Beardsley, are associated with wilt disease of pineapple under field conditions. Pseudococcus cryptus Hempel (Citriculus mealybug). In other insects with a none flying adult female, the first stage larvae or nymphs are able to disperse to new plants. The mealybugs tend to live where they can find ‘shelter’ such as pushing up against the veins of plants, moulted skins of other insects, or against scale insects such as the Flocculent flax scale.

Some were deliberately released into New Zealand to provide biological control of the Long-tailed mealybug and other pest species. Transmission experiments for the longtailed mealybug (Pseudococcus longispinus), showed that this mealybug is also a vector of PMWaV-2. The pink and gray strains were found primarily on different structures of the pineapple plant, and reproduced using different methods. It is presumed that the wax tails help balance the insect in flight. A third species, Pseudococcus longispinus (Targioni-Tozzetti) induces wilt symptoms in laboratory experiments, but not under field conditions. Aust. It is found on crops, naturalised plants and native plants. Reviewed September 2019.

This characteristic helps distinguish it from other mealybugs that may feed on the same hos… Mealybugs have a short white wax anal tube through which they excrete the excess sugary liquid, which is called honeydew. The most common species found in Hawaii’s pineapple plantings are D. brevipesand D. There are three female nymphal instars (stages) and two male nymphal instars. ... Long-tailed mealybug, Pseudococcus longispinus. Why is there so much white wax?Most mealybugs produce much white flocculent wax with which they are covered and which also covers the areas of plants they inhabit. Longtailed mealybug (Pseudococcus longispinus) • Wide host range: air plant, asparagus, avocado, banyan, begonia, betel- ... • Pineapple mealybugs are tended by several species of ants; control ants to help prevent serious mealybug infestations. After mating and when it is fully grown, the female mealybug settles on the plant and produces a white fluffy wax chamber around herself. Live specimens of Pseudococcus dendrobiorum most closely resemble the pineapple mealybug in appearance. The stylets are then gradually pushed into the plant and manoeuvred into the phloem (nutrient transport vessels) of the plant. The prepupa and pupa have wing buds. ParasitoidsTwelve parasitoid and hyperpeparasitoid wasps (Hymenoptera) have been reared from Long-tailed mealybugs in New Zealand. Integrated control of the long-tailed mealybug, Pseudococcus longispinus (Hom. Pineapple is an important crop in the State of Espírito Santo, Brazil, and there is a need for increased pest management information on the crop in this state. Hymenptrous parasitoids as a bioagents for controlling maybugs (Hemiptera: Pseudococcidae) in Egypt Egypt. Original publication date October 2016. Interesting Insects and other Invertebrates. At least 28 different species of ants tend mealybugs on pineapples. In early literature (sourced from the 1930s), it was thought that there were two strains of the pineapple mealybug and one species, named Pseudococcus brevipes. These predators include five species of ladybird (four adventive), larvae of two kinds of flies, predatory gall flies (Cecidomyiidae) and hoverflies (Syrphidae), and larvae of a lacewing. In Hawaii the longtailed and pineapple mealybugs are common on orchids. 11: 1-230. and Pseudococcus spp., Hemiptera: Sternorrhyncha: Pseudococcidae). Early detection of mealybug infestations allows implementation of appropriately timed control measures as soon as possible, and pheromone-baited traps are now used for monitoring Planococcus ficus (Signoret) (Hinkens et al. It can walk around the leaves where its cocoon was and it can fly to other leaves or to different plants. The pair of antennae and three pairs of legs are not visible from above. Walking, flying and dispersalThe adult male has legs and wings. Pseudococcus longispinus (Targioni Tozzetti), Icerya purchasi Maskell, and Icerya genistae Hempel. Long-tailed mealybug - Pseudococcus longispinus. Adult females and nymphs also have legs and can walk. After it has opened the back of the cocoon, its transparent wings (1 pair) expand and harden. Longtailed Mealybug Pseudococcus longispinus (Targioni Tozzetti) (Insecta: Hemiptera: Pseudococcidae)1 Morgan A. Byron and Jennifer L. Gillett-Kaufman2 1. Breeding is slower at the lower winter temperatures. The literature concerning the association between ants and the mealybugs causing pineapple wilt disease is surveyed. Another less common mealybug species, the long-tailed Pseudococcus longispinus, is occasionally seen in pineapple fields, and has also been found to be associated with mealybug wilt . These feeding stages grow by moulting (changing skin). The moulted prepupal and pupal skins are pushed out the end of the cocoon. The longtailed mealybug, Pseudococcuslongispinus (Targioni Tozzetti), is a widely-distributed pest that feeds on many economically important hosts, particularly tropical fruits and ornamentals.

Swirski E, Wysoki M, Yizhar J, Gurevitz E, Greenberg S, 1979. : Pseudococcidae), in avocado plantations in Israel. 1979. The body is yellowish-grey and may have a slightly darker stripe on its midline. In 1959, Beardsley demonstrated that the pink and gray strains were in fact different species. In South Africa, P. longispinus occurs on pineapple sufficiently frequently for there to be concern over disinfesting planting material (Petty, 1987); the species is also listed as a pest of guava (Villiers, 1978). Major hosts plants of the long-tailed mealybug are citrus, taro, avocado, guava, eggplant and grapevine. In Japan, Tabata et al. 105/32.
