Diamondback Moth And Its Management In Canola And Crop Weeds, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Diamondback moth larvae are a serious pest of canola, brassicas, and forage crops, and are difficult to control. The pest breeds up on summer weeds and volunteer canola plants. If there are abundant early rains and mild winters, diamondback moth larvae pose a risk to canola crops.

Russian Wheat Aphid And Its Management In Wheat And Barley, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Russian wheat aphid is found worldwide and has spread throughout all major grain growing countries. In Australia, Russian wheat aphid is present in South Australia, Victoria, New South Wales, Tasmania, and Western Australia, where it was first detected in 2020.

In Western Australia, Russian wheat aphid is found in low, medium, and high rainfall areas.

Presence of Russian wheat aphid in Western Australia is not an international trade issue and there are no trade implications for the grain industry, as bulk grain is not a host for Russian wheat aphid.

Managing Aphids And Viruses In Lupins, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Aphids reduce yields by direct feeding damage, which causes flower and pod abortion and occasionally plant death in lupins. The extent of damage varies between seasons, but losses can be severe in years that favour aphid population development.

Lupins are most vulnerable to aphids during budding and flowering, as severe feeding damage on growing tips can cause buds to drop, flowers to abort, and reduced pod set. Some lupin varieties are more susceptible to aphids than others.

Aphids transmit serious virus diseases, which reduce yields and contaminate seed stocks. Some species of aphids are more difficult to control than others.

Native Budworm Spraying Threshold, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

The number of native budworm caterpillars in a crop is the major factor determining potential economic damage from the pest. Table 1 was generated with results from department trials to provide an estimate of potential loss from native budworm damage.

Crop loss (kilograms per hectare (kg/ha)) for each caterpillar netted in 10 sweeps (or found per square metre (m2 )) is shown in Table 1. One caterpillar netted in 10 sweeps is equivalent to about 20,000 caterpillars/ha for most pulse crops, assuming an even distribution over the crop

All Peer-Reviewed Publications

The biology of Diachasmimorpha longicaudata (Ashmead) was studied on third instar larvae of Bactrocera dorsalis (Hendel) to optimize its mass rearing in the laboratory. The mean parasitoid emergence rate ranged from 55–92% during its first 13 days of life. The number of females was higher than that of males. The mean development time from egg to adult emergence was 20.14± 0.02 days in females and 17.72± 0.02 days in males. Fed females lived longer than fed males. Food-deprived females and males lived 72 hr after emergence. The lifespan of males and females was 16.42± 0.53 and 15.86± 0.35 days, respectively, …

Network Resilience Of Plant-Bee Interactions In The Eastern Afromontane Biodiversity Hotspot, Fairo F. Dzekashu, Abdullahi A. Yusuf, Kazuhiro Takemoto, Marcell K. Peters, H. Michael G. Lattorff, Ingolf Steffan-Dewenter, Christian W.W. Pirk

All Peer-Reviewed Publications

Interaction network resilience can be defined as the ability of interacting organisms to maintain their functions, processes or populations after experiencing a disturbance. Studies on mutualistic interactions between plants and pollinators along environmental gradients are essential to understand the provision of ecosystem services and the mechanisms challenging their network resilience. However, it remains unknown to what level ecological changes along climatic gradients constrain the network resilience of mutualistic organisms, especially along elevation gradients. We surveyed bee species and recorded their interactions with plants throughout the four major seasons (i.e. long and short rainy, and long and short dry) on 50 …

The Potential For Automated Insect Classification Using Infrared Remote Sensing, Rachel Deahl

Theses

Insects play an important role within ecosystems, occupying almost all trophic levels and providing crucial services such as pollination and decomposition. In addition, they can directly and negatively impact humans as crop pests, parasites, and disease vectors. Thus, it is essential to understand the spatial and temporal dynamics of insect populations and communities. Various forms of remote sensing, such as LiDAR, have been used to capture data on insects but often are costly and require advanced expertise. The objective of this thesis is to evaluate a cost-effective methodology that balances information loss. This thesis aims to outline the discrimination required …

Amphiphala, A New Genus And Its Three New Species From Eastern North America (Lepidoptera: Tortricidae: Cochylina), Michael A. Roberts, Michael Sabourin, John W. Brown

Insecta Mundi

Amphiphala Roberts and Sabourin, new genus (Lepidoptera: Tortricidae), is proposed for three new species: A. liatriana Roberts and Sabourin, new species; A. landryana Brown, new species; and A. carolana Sabourin, new species. The genus is recorded from the eastern part of North America from Ontario, Canada south to South Carolina, and west to Manitoba and Mississippi. Owing to its superficial similarity to the banded sunflower moth, Cochylichroa hospes (Walsingham, 1884), Amphiphala remained hidden in North American Lepidoptera collections. Amphiphala liatriana has been reared from northern blazing star, Liatris scariosa (L.) Willd. (Asteraceae), in Maine.

Challenges In Assessing Repellency Via The Behavioral Response By The Global Pest Tribolium Castaneum To Protect Stored Grains, Leslie Catherine Rault, William R. Morrison Iii, Alison R. Gerken, Georgina Bingham

Department of Entomology: Faculty Publications

Background: Food security is an increasingly pressing global issue, and by 2050, food production will not be sufficient to feed the growing population. Part of global food insecurity can be attributed to post-harvest losses, including quantity and quality losses caused by stored-product pests like insects. It is thus timely to find management strategies to mitigate these losses and counteract food insecurity. The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), a global stored-product pest with a wide range of food sources, was used in this study to assess repellency to a selection of essential oils. Methods: Multiple behaviorally relevant methods …

Pastoral Grasses And Legumes As Potential Host Plants For Fall Armyworm Spodoptera Frugiperda (J.E. Smith) Development, Saleh Adnan, Holly Cattermole, Kim Saligari, Helen Spafford

Grain and Other Field Crops Research Articles

The fall armyworm, Spodopterafrugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is a highly polyphagous, migratory pest native to the tropical and subtropical region of Americas. Grass crops particularly corn have been most heavily impacted since S. frugiperda invaded Australia in 2020. In northern Western Australia, S. frugiperda is primarily a problem in dry season (May to October) crops when there are abundant host plants available in monocultures. During the wet season (November to April) it is not known what host plants may support larval growth and development. Accordingly, this present study undertook a no-choice feeding bioassay to assess larval and pupal …

Exploring The Roles Of Physiology And Phylogeny In Novel Signal Evolution, Mia E. Phillips

Dartmouth College Ph.D Dissertations

In animal communication, signal phenotypes are shaped by a combination of selective

forces pushing for improved transmission, efficiency, and detection, and limited by

developmental constraints in signal production and reception abilities (Morton 1975; Guilford &

Dawkins 1991; Endler 1992; Davranoglou et al. 2023). These opposing forces have resulted in

communication strategies that are broadly diverse yet similar among closely related species. We

expect to see gradual changes in signal phenotypes across different clades (Harvey & Pagel

1991). Sometimes, though, the communication strategies of closely related taxa are drastically

different (Ligon et al. 2018), indicating that selection must have overcome the …

Homocopris Burmeister, 1846 (Coleoptera: Scarabaeidae): Lectotype Designation For Copris Torulosus Eschscholtz, 1822, And Correction On The Geographic Distribution Of The Two Chilean Species, José Mondaca, Fernando Z. Vaz-De-Mello

Insecta Mundi

Homocopris Burmeister, 1846 (Coleoptera: Scarabaeidae) is a small genus of South American dung beetles composed of four species distributed in Argentina, Brazil, and Chile. Recently, a neotype was designated for Copris torulosus Eschscholtz, 1822 (currently H. torulosus) based on the assumption that the original type series had been lost. However, this designation is invalid for failing to comply with articles 75.2, 75.3, 75.3.1, and 75.3.4. of the International Code of Zoological Nomenclature. Furthermore, even if it had been nomenclaturally valid, the neotype now loses its type status because we found a syntype in the material of the Johann …

Analysis And Tritrophic Associations Of Bats, Bat Flies, And Laboulbeniales Microfungi In Kenya, Ally Willis

Masters Theses & Specialist Projects

Bats (Chiroptera) are host to diverse lineages of ectoparasitic arthropods including ticks, mites, fleas, bat bugs, and bat flies (Arthropoda). Streblidae and Nycteribiidae are families in the dipteran superfamily Hippoboscoidea, and these hematophagous ectoparasites and their host associations are relatively well studied in the American tropics but not as well in east Africa. One of the main properties of host-parasite systems is host specificity, with some Eastern Hemisphere species (Nycteribiidae) appearing to display a lower level. The morphology of bat flies may drive (or be the result of) niche partitioning on the landscape of the host. Streblid bat flies in …

The Evolution Of A Response To Smoke Within The Arthropoda, Adam Miles

Masters Theses & Specialist Projects

Many animals have a survival instinct to flee in response to fire, but do they respond to smoke alone? Many arthropods respond to fire or smoke by moving in the opposite direction (a negative taxis) to obtain shelter. At the species level, taxa that have adapted a behavioral response to fire increase their fitness. This response behavior has been observed in many terrestrial arthropods. Still, the behavior is currently unknown for marine, aquatic, or cave arthropods, which are atypically exposed to smoke or fire. This project assesses how often behavioral adaptation to smoke avoidance may have evolved within Arthropoda. Twenty-two …
