Biostatus and Distribution
This adventive plant hopper from Australia has been in Zealand since before 1880 and is now widespread in lowland (below 500 m) areas of the North Island and in Nelson and Marlborough in the South Island. It occurs on its herbaceous, shrub and tree host plants in city gardens and parks as well as native ecosystems. Its feeding results in production of a lot of honeydew which makes plants sticky and black from sooty moulds.
Conservation status: Widespread, a pest on some garden and crop plants.
Life Stages and Annual Cycle

The Passion vine hopper has one generation per year. It overwinters as eggs. The egg stage has an obligatory diapause (resting stage). Nymphs hatch in late spring and adults are present from summer until early winter. Adults and nymphs tend to aggregate on the actively growing shoots and leaves and feed on sap from the phloem.
The adults are about 5-6 mm long and have broad triangular forewings that are clear with a mottled dark brown-black pattern. The head, thorax (middle part of body) and abdomen are pale brown. They have three pairs of legs and two pairs of wings. They jump if disturbed as well as being able to fly. On the underside of the head the rostrum extends between their legs. It contains the stylets, long rods, that are used for feeding. Adults take two weeks to mature. Mating commences at dusk. Egg laying occurs in late afternoon and evening.
The female lays eggs preferentially in dead plant tissue including timber structures such as garden stakes, but will also lay in soft live plant stems and leaf midribs. The eggs are inserted in long rows. The sharp ovipositor prepares a hole into which is inserted the pale ovoid egg (about 1 mm long). The pulped material at the hole entrance is compacted to form a protective plug, though some fibres remain obvious.
Upon hatching, the newly emerged nymphs move to succulent shoots to feed. They often gather near the tips of the shoot. There are five nymphal instars (stages). They grow from 1 mm long to 5 mm and go from nymphal instar to the next by moulting. During moulting, the skin on the dorsal side splits and the next stage pulls itself out of the old skin. The nymphs are pale with brown markings and have a white tuft of white filaments on the end of the abdomen. They can move the tuft of filaments up and down. It is usually held upright. Like the adults, they have three pairs of legs and can jump. They also have a rostrum with stylets for feeding on plant sap.
Walking and flying
The nymphs and adults have three pairs of legs that are used for walking. When they are disturbed they can hop. The adults have two pairs of wings held over their body and used for flying.
Feeding
Like other Hemiptera, the Passion vine hopper has piercing and sucking mouth parts. The long stylets, special shaped rods, are held in the rostrum. When it wishes to feed, the bug moves the tip of the rostrum to a suitable part of the plant. The stylets are then gradually pushed into the plant. The stylets form two tubes, one through which saliva is injected into the plant and a second through which plants juices are sucked up into the insect. The Passion vine hopper feed on plant sap in the phloem. Excess liquid is secreted as honeydew. They produce a lot of honeydew that coats plant leaves. Black sooty moulds may grow on it.

Recognition
Of the three common Australian plant hoppers, adult Passion vine hoppers are the most distinctive and easiest to recognise. They have transparent wings with mainly dark brown-black markings. The wings are held over their body like a low tent. The head and body are pale brown. The Green planthopper, Siphanta acuta (Flatidae). and Grey hopper, Anzora unicolor (Flatidae), are as their name suggests green and blue-grey respectively. The wings are held over their body like a steep roof.
The nymphs of the Passion vine hopper require a little more skill to identify. They are often called ‘fluffy bums’ because of their fluffy wax tail. Both the Green and Grey planthoppers also have fluffy wax tails, but the tail of the Passion vine hopper sticks up most of the time, while the tail of Green planthopper nymphs tends to lie flat. The larger Passion nymphs are red-brown with pale markings. The nymphs of the Green planthopper may be green or pale with a few red markings. The nymphs of the Grey planthopper are mostly covered with lots of wax. They have a fluffy wax tail that is usually held flat and towards the front they may have wax horn-like structures.

Natural Enemies
Pathogens, parasitoids and predators have been found. In addition, Rob Cumber in his 1966 paper reported that wood boring larvae of caterpillars and beetles may incidentally kill overwintering eggs. This kind of unintential killing is sometimes called ‘malentities’.
Pathogens
Five fungal pathogens of the Passion vine hopper are known in New Zealand. Hirsutella species may be seen on dead adults and nymphs on the underside of leaves in the Autumn. A survey of Kiwifruit Orchards reported by Marshall and colleages in 2003 found that several strains of an insect pathogen, Lecanicillium muscarium (Petch) Zare & W. Gams, were present. One of the strains was later made into a commercial pesticide for control of Passion vine hoppers in Kiwifruit orchards.
Parasitoids
Two wasp egg parasitoids of the Passion vine hopper are known in New Zealand. They can kill a high proportion of eggs. Ron Cumber in his 1966 paper reports that Centrodora scolypopae Vallentine, 1966 was first found in August 1962 at Paihia, Bay of Island, Northland. The female wasp is much larger than the male. There may be 1-4 wasps in a Passion vine hopper egg. Parasitised eggs are pale with a dark half band at one end. Parasitoid development is delayed so that the adults emerge in the late summer when new season passion vine hopper eggs are available. North of Auckland upto 87% of Passion vine hopper eggs may be parasitised. Dr Gerad in one of her 1989 papers on the egg parasitoid, found depth in a plant of Passion vine hopper eggs varied with host plant and that the proportion of eggs that were parasitised was greater in shallow eggs.
The second parasitoid Ablerus sp. was discovered by SJ Harcourt while doing research for his MSc at Auckland University and published in 1995. John Charles and Doug Allen in reported in 2004 that both Ablerus sp. and Centrodora scolypopae were widespread in the North Island.
Predators
One of the predators, an unnamed mite, Pyemotes sp. (Acari: Pyemotidae) also feeds on eggs during the winter. It will feed on eggs that have been parasitised.
One bird and several spiders and predatory insects have been recorded feeding on Passion vine hoppers.

Host Plants
Passion vine hoppers are found on many plants including native species. The list of host plants is far from complete. It may be easier to list plants on which Passion vine hoppers do not feed!
They occur on garden plants, and are often present in large numbers. Their feeding can cause shoots to wilt and young leaves to be damaged. The secretion of honeydew causes plants to become sticky and sooty mould fungi may develop. Sooty mould on fruit of commercial crops of Kiwifruit can cause rejection of fruit for export.
As well as causing feeding damage to plants, egg laying also damages soft growths such as narrow stems, leaf veins and stalks and tendrils.

Honeydew Feeding
Passion vine hoppers feed on the sap in the phloem of plants and excrete excess water and sugars. This is called honeydew and often coats the leaves of plants. Ants and honey bees have been recorded feeding on the honeydew.
Source of poisonous honey
In 1947, C.R. Paterson published a paper that showed that poisonous honey was made by honey bees feeding on honeydew secreted by Passion vine hoppers feeding on Tree tutu, Coriaria arborea Linds. (Coriariaceae). They fed on the honeydew at a time when nectar from flowers was scarce.

Control
Commercial Crops
Where passion vine hoppers are a problem on commercial crops, growers should consult their professional organisation and/or product group for control option.
Home Garden
Passion hoppers may be found on plants in most gardens. If possible, avoid growing plants that are very susceptible to passion vine hoppers. If you feel that you need to use pesticides to assist with their control, consult your local horticultural supplier or garden centre for suitable products.
You need to be aware that the older nymphs and adults are very mobile and can reinfest plants from nearby areas. If you want to apply a pesticide to control passion vine hopper, the most effective stages to target are the very small nymphs.
Non-pesticide options
One way to reduce the populations of passion vine hoppers is to remove all the bits of plant with eggs. Wait until the adults have finished laying eggs, about mid to late May. Then carefully go round the garden and cut off all the dead and live stems and leaves with their typical egg scars and tufts. You can bury them or destroy them in some other way.
You could even provide suitable egg laying material for the adults and harvest it after egg laying has finished. Look to see what they like in your area and hang small bundles of it plants with passion vine hopper. Start this about mid-February.
Having collected all the eggs, you could try to enhance their biological control by increasing the population of egg parasitoids. Keep all the bits of plants with eggs in a container. Ensure that they remain slightly damp, but not obviously wet and that the tiny newly hatched passion vine hopper nymphs cannot get out. Allow the nymphs to hatch and die, then in January open up the container outside. With luck the tiny egg parasitoids will hatch out in late January and February and find new passion vine hopper eggs in which to lay their eggs.

Additional Information
Research Project
The overwintering eggs enter an obligatory diapause. This means that egg development cannot be completed until after certain environmental conditions have been met. It could be day length exceeding a particular length, or that the eggs have experienced a certain number of days below a particular temperature. It would be useful to know the key environmental factors that trigger the end of diapause. It would also be interesting to know if all eggs enter diapause irrespective of environmental conditions or if all eggs enter diapause irrespective of environment.
