Impacts Of Cruciferous Extracts On The Parasitism Efficiency Of Diadegma Insulare; A Hymenopterous Parasitoid Of The Diamondback Moth, Muhammad Sajid Qureshi, Wali Muhammad, Muhammad Adnan Bodlah, Abdul Mannan Hamzah, Muhammad Saeed, Riaz Hussain

Journal of Bioresource Management

Herbivore's attack stimulates chemical production in the plants; that communicates with natural enemies (chemical communication) and urges them for help (i.e. cry-for-help phenomenon). Such chemicals play an important role to attract the parasitoids and increase the chances of host pests' encounter. Current studies were performed to observe the extracts' efficacy in order to attract the parasitoid (i.e. Diadegma insulare) and thereby increase the likelihood of encounter with the host pest (i.e. Plutella xylostella). Cruciferous cultivars' extracts were developed and applied with artificial release of parasitoids under semi-field conditions. Findings revealed that extracts had the potential to enhance the …

A New Record Of Fleas From Nilgai Antelope In Southern Texas And Fleas From Other Wildlife, Sarah E. Mays Maestas, Jason Tidwell, John A. Goolsby, Lauren P. Maestas

School of Integrative Biological & Chemical Sciences Faculty Publications

Wildlife are hosts of ectoparasites, such as fleas and ticks that may transmit human and animal pathogens. Little is known about the ecology of many ectoparasite species native to southern Texas, or their role in pathogen maintenance and transmission. Much attention has been given to the role of nonnative nilgai antelope as cattle fever tick hosts and agents of dispersal, but little attention has been given to other ectoparasites that may utilize nilgai antelope as hosts. As southern Texas is a hot-spot for flea-borne (murine) typhus, it is important to examine flea species presence, abundance, and host use in this …

Buzzworthy Messaging: Assessing Residents’ Perceptions Of Labels To Better Promote Pollinator Gardening, Colby J. Silvert, Laura A. Warner, Cody Gusto, John M. Diaz, Rachel E. Mallinger

Journal of Extension

Consumers appear more likely to purchase plants with labeling indicating pollinator-friendly production or high pollinator resource value. No standardized label for pollinator-supporting plants or landscape practices exists in the United States, which has proliferated the variety of labels used by the industry. This mixed-methods study aims to provide insight into residents’ preferred pollinator-related labelling for plants and landscape practices in order to help Extension professionals and green industry stakeholders improve outreach, marketing, and communications efforts. Findings suggest a butterfly-friendly label would be most effective for marketing while residents would accept and favorably perceive labels emphasizing either pollinator-friendly or bee-friendly attributes.

Bean yellow mosaic virus (BYMV) is an aphid-transmitted virus that commonly causes necrotic symptoms that kills lupin plants when infected early before pod set. When plants are infected after pod set, black pods develop (known as black pod syndrome).

BYMV is found predominantly in high rainfall areas of the Western Australian (WA) grainbelt. This page outlines the symptoms, diagnosis, factors favouring disease risk and spread, yield and quality impacts, and management for BYMV in lupin crops in WA

Wheat Streak Mosaic Virus And Wheat Curl Mite And Their Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Wheat streak mosaic virus (WSMV) is a seed and mite-borne virus that infects wheat, causing severe leaf symptoms and reduced yields. The symptoms and damage are more severe in wheat than other hosts, in which infection is symptomless.

Wheat streak mosaic virus can cause crop failure when widespread infection occurs in seedling wheat, particularly when a heavily WSMV-infected green bridge is not controlled before sowing an early crop, and warm temperatures favour mites.

Wheat curl mite (Aceria tosichella) is the only known vector of WSMV. It can transmit the virus in its nymph and adult stages.

Armyworms And Their Management In Cereal Crops, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Armyworms are pests of cereals crops. They are frequently found along the south coast of Western Australia and occasionally in other grainbelt locations.

When barley crops are maturing in spring, large armyworm caterpillars climb plants and can chew through the stems, causing the heads to fall to the ground. Damage to wheat and oat crops occurs less frequently and is usually minor compared to damage in barley. Armyworms are seldom a serious problem in pastures.

The Mutual Effects Of Pinching And Promalin® On Root Architecture In Two Boxwood Species, Omer Sari, Fisun Celikel

The Philippine Agricultural Scientist

Boxwoods are constantly pinched to shape and form hedges, and Promalin® application is used to boost their shoot yield. Having good root development is crucial for the healthy development of plants; however, the effects of such applications on plant root development have generally been ignored in previous studies. Hence, this study evaluated the effects of applications on the root growth of two boxwood species (Buxus sempervirens L. and Buxus balearica Lam.) during the summer dormancy period. Pinching and Promalin® (0, 1 000, 2 000, and 4 000 ppm) were applied to one-year-old seedlings at three different times. Results showed …

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

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 …
