“…(Table 4.2). These differences are consistent with the southerly geographical distribution of A. nitida (≈34°S 151°E-≈ 23°S 150°E) and the more northerly distribution of A. l. lutescens (≈27°S 153°E-≈10°S 142°E) (Donaldson 1983;Danne et al 2014).…”

“…Both species are thought to have originated from Australia's rainforest regions (Brimblecombe 1948). In broad terms, A. l. lutescens is found along coastal regions from Brisbane (c. 27°S 153°E) to the Torres Strait Islands (c. 10°S 142°E), and A. nitida is found along coastal areas from Wollongong (c. 34°S 151°E) to Rockhampton (c. 23°S 150°E) (Donaldson 1983). Notably, because of the relatively low population densities of fruitspotting bugs and because they are difficult to detect without first observing damage to the host plant, it is likely that current records underestimate their true distribution.…”

“…Notably, because of the relatively low population densities of fruitspotting bugs and because they are difficult to detect without first observing damage to the host plant, it is likely that current records underestimate their true distribution. Reports of A. nitida have also come from as far north in Queensland as the Iron Range in Cape York (c. 11°S 142°E) and as far west as the Carnarvon Range (c. 25°S 149°E) in southern Queensland (Donaldson 1983 (Peng et al 1995(Peng et al , 2012, as well as at Lake Argyle Village, 435 km WSW of Katherine (Lever 1982), and from the Ord River area (c. 16°S 128°E) of Western Australia (Smith 1985).…”

Australian fruitspotting bugs, Amblypelta nitida Stål and A. lutescens lutescens Distant (Hemiptera: Coreidae), and the potential for their biologically based management in macadamia orchards

Australian fruitspotting bugs, Amblypelta nitida Stål and A. lutescens lutescens Distant (Hemiptera: Coreidae), are major economic pests of macadamia nuts in Australia. They are also pests of approximately a dozen other tropical and subtropical horticultural crops, and minor pests of many more. They are endemic to the east and northern coastal regions of Australia and as such are distributed across the entire growing region of Australia's macadamia industry. Although the industry is reliant on synthetic pesticides for several major pests and diseases, including fruitspotting bugs, biological control of a major pest, the macadamia nutborer, Cryptophlebia ombrodelta Lower (Lepidoptera: Tortricidae), has been successful and is widely adopted. This success has set a precedent within the macadamia industry and provided incentive for research and development of other biological control agents for other important pests. In the early 1990s, a hymenopteran egg parasitoid, Anastatus sp. (Eupelmidae), was identified as having potential as a biological control agent for fruitspotting bugs in Australia, and in 2010, mass rearing began. No formal studies on Anastatus sp., apart from initial releases conducted after its discovery, had been done prior to this thesis.A study on the potential for conservation biological control of fruitspotting bugs in macadamia orchards using habitat management was conducted over two years in northern New South Wales.Traditionally, trees in macadamia orchards are spaced such that the orchard canopy closes over when the trees reach maturity, shading out any existing ground-cover vegetation. In recent years, macadamia growers have been encouraged to adopt wider spacing and/or pruning techniques to increase light into their orchards for improved tree health and nut production. In this situation, common practice is to grow the shade-tolerant sweet smother grass in the mid-row; this provides ground-cover but does not increase floral diversity. In this study, open mid-row canopies, with resident, weedy, flowering mid-row ground-cover vegetation, were compared to closed mid-row canopies with no ground-cover vegetation in terms of a) pest and beneficial invertebrate abundance, b) predation levels of sentinel A. nitida eggs and c) levels of nut damage by A. nitida. The results showed a stark contrast between 'light' and 'dark' orchards; open canopy orchards ('light' orchards) harboured a significantly higher abundance of beneficial invertebrates than denser canopy orchards ('dark' orchards), whereas in 'dark' orchards the abundance of a major pest, the macadamia lace bug, Ulonemia concava Drake (Hemiptera: Tingidae), was significantly higher.Not a single fruitspotting bug was sampled during this experiment; however, damage levels to nuts were significantly lower in 'light' orchards compared to 'dark' orchards. Levels of predation on ii sentinel A. nitida eggs were variable and did not show any clear pattern that could be attributed to orchard management type. In two field release experiments, the...

Amblypeltaspp. (Hemiptera: Coreidae) and green fruit drop in lychees

The fruitspotting bug Amblypelta nitida Stål., was responsible for more than 93.5% of green fruit drop in lychees in 1985/1987 at Maroochy Horticultural Research Station, Nambour (lat. 27 °S). A. nitida at other locations in southeast Queensland and A. lutescens lutescens (Distant) in north Queensland (lat. 17 °S), caused green fruit drop ranging from 24.8% to 98.5%. These results suggest that fruitspotting bugs may be the most important factor inducing lychee fruit abscission in some areas.

Male-specific volatiles from nearctic and Australasian true bugs (Heteroptera: Coreidae and Alydidae)

et al. 1993

Aeration and exocrine gland extracts were analyzed for three Coreidae and two Alydidae. Males of all the species studied emit volatile blends that are probably pheromones, but sexual communication in these insects evolved differently. In the alydids,Riptortus serripes andMirperus scutellaris, the metathoracic scent glands are sexually dimorphic, and the dimorphisms are expressed chemically. Secretions from the male alydids contain high concentrations of esters or alcohols [e.g., (E)-2-hexenyl (Z)-3-hexenoate, (E)-2-hexenyl butyrate, and (E)-2-octenol], while females produce mainly acids and aldehydes [e.g., butyric and hexanoic acids, and (E)-2-hexenal]. In the coreids,Amblypelta lutescens lutescens, Amblypelta nitida, andLeptoglossus phyllopus, the metathoracic scent glands are not sexually dimorphic, but male- and species-specific volatiles are released, apparently from cells in the cuticular epidermis. The coreid male-specific volatiles are primarily monoterpenes and sesquiterpenes, including (-)-(3R)-(E)-nerolidol as the major component fromA. lutescens lutescens (an Australasian species) andL. phyllopus (a Nearctic species). Only (+)-(3S)-(E)-nerolidol is commonly found in plants so (E)-nerolidol from these coreids is environmentally unique because of its chirality.
