A laboratory study investigated the predation and development rates of Tasmanian lacewing larvae (Micromus tasmaniae) under constant and fluctuating temperature regimes Larval development and consumption of second instar cabbage aphid (Brevicoryne brassicae) increased linearly with constant temperatures between 1030C Under fluctuating daily temperatures (1025C) development and consumption rates were equivalent to those found at a constant 25C Larvae consumed more aphids during later instars and a maximum consumption rate of approximately 10 aphids per day was recorded Some aspects of larval behaviour are described

Abstract:
Micromus tasmaniae Walker is an important predator of a number of economically important pests such as aphids The largerthebetter theory predicts that reproductive fitness is positively linearly associated with body size or weight To test whether larger insects perform better reproductively the insect population was divided into three weight groups light average and heavy and the reproductive performance of nine breeding treatments (three male weights three female weights) was assessed The body weight of female M tasmaniae had no significant effect on reproductive fitness in terms of fecundity fertility fertility rate oviposition period and longevity suggesting that female size variation is of secondary importance in determining reproductive fitness in this species Male size had significant positive effect on female fecundity fertility and fertility rate and reproductive period This suggests that heavy males may transfer larger ejaculates that provide more sperm and malederived nutrients to females than light males

The tomato/potato psyllid (TPP) Bactericera cockerelli (Sulc) (Hemiptera Triozidae) has been regarded as a significant pest of solanaceous crops in New Zealand since its discovery in 2006 Current management of TPP relies primarily on the use of insecticides A better understanding of the role of beneficial insects in the control of TPP is needed to guide future Integrated Pest Management (IPM) strategies In Canterbury 201011 the seasonal abundance of TPP and beneficial insects was monitored in a lowspray potato crop using yellow sticky traps and incrop plant assessments The brown lacewing (Micromus tasmaniae) was the most abundant beneficial insect encountered followed by ladybird species (Adalia bipunctata and Coccinella undecimpunctata) Numbers of adult brown lacewings and ladybirds peaked on sticky traps in December 2010 while adult TPP numbers peaked in February 2011 Brown lacewing eggs were present on potato plants throughout the season with the highest numbers found during January/early February 2011 Numbers of all life stages of TPP were highest on potato plants from mid January to the end of the monitoring period in mid February 2011 (crop sprayoff)

Abstract:
The impacts of naturally occurring predators for control of Bactericera cockerelli (tomatopotato psyllid; TPP) have been assessed in potatoes at Pukekohe for 3 years Results indicate that the most commonly found predator species are Micromus tasmaniae (brown lacewing) and Melanostoma fasciatum (small hoverfly) with populations of small hoverfly eggs and larvae reaching up to almost 200 per plant in unsprayed plants over January and February Continuing with intensive studies on TPP these naturally occurring predators appear to be important biological control agents In laboratory choice and no choice assays results indicate these two predator species eat all life stages of TPP even in the presence of aphids The intraguild interactions between predator species are now being investigated to ascertain from a suite of predators on potatoes which are likely to be the best allies in developing an Integrated Pest Management (IPM) programme for potatoes Laboratory studies indicate that larvae of small hoverfly and larval and adult life stages of Coccinella undecimpunctata (11spotted ladybird) may be displacing brown lacewings

Abstract:
AbstractField trials were conducted at four Canterbury, New Zealand locations in 2005–06 to determine if the synergistic effects of biological control by natural enemies and standard drenching techniques controlled lettuce aphid populations throughout the entire growing season. Chemical usage significantly lowered aphid densities in the outer, wrapper and heart leaves compared to control plants at most times. However, in mid-summer, natural enemies, such as the brown lacewing (Micromus tasmaniae), 11-spotted ladybird beetle (Coccinella undecimpunctata) and small hoverfly larvae (Melanostoma fasciatum), were more than sufficient to control lettuce aphids without the use of insecticides. Drenching, in addition to natural enemy attack, appears to be required in early spring and late summer to maintain very low levels of lettuce aphid. Given the potential for imidacloprid resistance to develop, it may be advisable to restrict drenches to these key periods in order to allow populations of natural enemies to maintain control of prey populations. We recommend industry support the validation of action thresholds across different regions within New Zealand and focus on the seasonal biology of predators to assist growers with the sustainable long-term control of lettuce aphids. The inclusion of additional data into an economic model to compare pest damage with predator loading would be useful for growers in managing aphid problems. These results will assist in the continued improvement and development of a sustainable IPM strategy for lettuce aphids in New Zealand and elsewhere.

Full text
Abstract:
AbstractOmnivory is common among arthropods, but little is known about how availability of plant resources and prey affects interactions between species operating at the third and fourth trophic level. We used laboratory and field cage experiments to investigate how the provision of flowers affects an omnivorous lacewing, Micromus tasmaniae (Hemerobiidae) and its parasitoid Anacharis zealandica (Figitidae). The adult lacewing is a true omnivore that feeds on both floral resources and aphids, whereas the parasitoid is a life-history omnivore, feeding on lacewing larvae in the larval stage and floral nectar as an adult. We showed that the effect of floral resources (buckwheat) on lacewing oviposition depends on prey (aphid) density, having a positive effect only at low prey density and that buckwheat substantially increases the longevity of the adult parasitoid. In field cages, we tested how provision of flowering buckwheat affects the dynamics of a four trophic level system, comprising parasitoids, lacewings, pea aphids and alfalfa. We found that provision of buckwheat decreased the density of lacewings in the first phase of the experiment when the density of aphids was high. This effect was probably caused by increased rate of parasitism by the parasitoid, which benefits from the presence of buckwheat. Towards the end of the experiment when the aphid populations had declined to low levels, the effect of buckwheat on lacewing density became positive, probably because lacewings were starving in the no-buckwheat treatment. Although presence of buckwheat flowers did not affect aphid populations in the field cages, these findings highlight the need to consider multitrophic interactions when proposing provision of floral resources as a technique for sustainable pest management.

Abstract:
Recent advances in molecular genetics have enabled a great deal of information about species to be obtained from analysis of non-invasively collected samples such as scat. Scat provides genetic information via residual host DNA on the outside of the scat, via characterising the genetic makeup of intestinal microbes that are present in the scat, or by examining the DNA remnants of prey items that have passed through the animal’s digestive tract. In this review, we provide a case study to demonstrate how these approaches are being used to better understand the threatened Tasmanian devil in the landscape, and to support the species’ conservation. Scat analysis enables us to quantify the genetic diversity of remote populations, where trapping is logistically challenging. We are beginning to learn how conservation management impacts the microbiome of threatened species, and investigate how various management strategies may be impacting the diverse array of bacteria and viruses that devils, like all animal species, are host to. We are using scat samples to better understand the interaction between devils and other animals in their environment by learning more about what they eat. We explore the strengths and challenges of these approaches by comparing our work to that conducted in other species. Finally, we provide specific examples of how our results are being integrated into conservation strategy for the devil.
