“…It would appear that lablab is an attractant for many predatory insects/spiders as numbers of these species were greater on lablab than on pumpkin in the pumpkin-only treatment. As shown by Qureshi et al (2010), lablab could, therefore, be used as a potential companion or field boundary crop in cucurbits to enhance natural enemy populations for the control of sucking insect pests, especially SLW.…”

Silverleaf whitefly (SLW, Bemisia tabaci MEAM1) and aphids are sap-sucking insects, which pose a serious threat to Australian cucurbit crops and the horticulture industry. Traditional chemical control for these insect pests is becoming less effective, and there is a need to search for alternative or supplementary methods. This study aimed to manipulate the habitat of pumpkin crops in a tropical setting (Queensland, Australia), by growing pumpkins (var. Japanese pumpkin) alone and between lablab (Lablab purpureus L. Sweet). It was hypothesized that the presence of lablab will increase the populations of natural enemies, and through their control of insect pests such as SLW and aphids, will affect pumpkin yield. The population of arthropods (natural enemies and pests of pumpkin), with a focus on SLW and aphids, were sampled weekly on both lablab and pumpkin crop for a total of 21 weeks. Results showed that lablab hosted more enemies of SLW per plant than pumpkin in either treatment. In addition, adult SLW numbers were significantly higher in the pumpkin-only crop compared with the pumpkin grown between lablab, while pumpkin in the mixed plantings had significantly more ladybirds and lacewing larvae (P < 0.05). While there was no significant difference in the average fruit weight between treatments, the total weight (kg) and number of marketable pumpkins per hectare was greater (P < 0.05) for the pumpkin/lablab treatment than the pumpkin-only treatment. This study shows that growing lablab alongside a pumpkin crop may enhance natural enemies of SLW and could significantly increase the yield.

“…In horticultural systems, several natural enemies attack aphids on different crops. For example, significant control of A. gossypii was observed by C. transversalis and Mallada signata Schneider (Neuroptera: Chrysopidae) on cucurbit crops (Qureshi et al . 2010).…”

Functional response of two common Australian predators, Dicranolaius bellulus (Guérin-Méneville) (Coleoptera: Melyridae) and Micraspis frenata (Erichson) (Coleoptera: Coccinellidae), attacking Aphis gossypii Glover (Hemiptera: Aphididae)

The red and blue beetle, Dicranolaius bellulus (Guérin-Méneville) (Coleoptera: Melyridae), and the striped ladybird beetle, Micraspis frenata (Erichson) (Coleoptera: Coccinellidae), are two widespread predators in Australian agroecosystems. However, very little is known about their biology and their potential as predators of agricultural pests. Here functional response studies for these two predators against the melon aphid Aphis gossypii Glover (Hemiptera: Aphididae) are reported. Prey consumption rates for females of both predators were assessed for five aphid densities using clip-cages around leaves of living melon plants (Cucumis melo L.) in the laboratory. A type I functional response for D. bellulus was obtained, with a constant linear increase in the number of aphids consumed, and an attack rate of 0.152 day -1 . In contrast, M. frenata showed a type II functional response, with an attack rate of 0.464 day -1 , and a handling time of 0.007 day, estimated by the random predator equation. M. frenata showed a trend of having a higher predation rate than D. bellulus, but this was only significantly at low prey densities. The maximum predation rates observed were 39 and 60 aphids per day for D. bellulus and M. frenata, respectively. This is the first study that demonstrates predation of D. bellulus on aphids and describes the functional response of both predatory beetles. The predatory efficacy shown here combined with their ability to tolerate low prey densities when alternative food resources are present suggests that these two predators can potentially play an important role in aphid suppression in Australian agroecosystems.

“…Chrysoperla congrua is a widespread species known from parts of northern and central Australia but absent from much of the east and south of the continent. Other green lacewing species in Australia include M. signata (not included in this review; Qureshi et al 2010). In contrast to the green lacewing, we found 21 articles related to brown lacewings, Micromus spp.…”

Identifying critical research gaps that limit control options for invertebrate pests in Australian grain production systems

Integrated Pest Management (IPM) is often described as a knowledge-intensive approach to invertebrate pest management, requiring information on the biology, ecology and phenology of a pest combined with an understanding of the interactions between crop growth and pests and between pests and their natural enemies. We conducted a systematic quantitative literature review to summarise what is known about pest and natural enemy species common to Australian grain production systems, based on 1513 published and unpublished research studies. Drawing on this information, we address three issues: what are the knowledge gaps in relation to grain pests and their natural enemies, do these knowledge gaps limit the development of an IPM package for grain growers in Australia and what further ecological or biological information might growers require to enhance the use of IPM approaches for managing pests? The main gaps identified include a lack of understanding around specific factors that lead to pest outbreaks or factors that could be useful for predicting when and where pest outbreaks will occur in the future. Monitoring techniques for many pests are not well developed, and therefore, it is difficult to link the density recorded in a field with crop damage and yield loss and to develop economic thresholds that can be linked with intervention decisions. For most natural enemies, the impact in terms of reduction in pest numbers has not been quantified, with very few studies including both pests and natural enemies together. There is large variability in the level of control provided by natural enemies between years and regions, and the factors leading to this variability are not well understood. Finally, the lack of taxonomic resolution for individual species within groups is identified as a critical knowledge gap. We suggest that a more comprehensive fundamental knowledge base is required across the invertebrate community in grain systems aimed at reducing insect pest outbreaks, combined with a greater depth of understanding in monitoring strategies for pests that contribute to pesticide-use decisions.
