What is parasitoid in crop protection?5 answersParasitoids play a crucial role in crop protection by utilizing living organisms to control pest populations effectively. These organisms, such as wasps belonging to Hymenoptera, Diptera, Coleoptera, Lepidoptera, and Neuroptera, lay their eggs in or on host insects. Upon hatching, the parasitoid larvae consume the host, ultimately leading to its death. In the context of biological control, egg parasitoids like Trichogramma species are extensively used to combat agricultural pests, particularly Lepidopteran insects, by targeting their eggs. However, caution is necessary when using parasitoids like Tamarixia radiata in citrus orchards to control the Asian citrus psyllid, as they can potentially acquire and transmit pathogens like Candidatus Liberibacter asiaticus, compromising their biocontrol efficacy. Successful cases, such as the introduction of Anagyrus lopezi to combat the cassava mealybug in Southeast Asia, demonstrate the significant benefits of utilizing parasitoids for sustainable pest management in agriculture.
What is trichuris trichiura?5 answersTrichuris trichiura, also known as whipworm, is a parasitic infection that affects humans. It is one of the major parasitic infections, along with Ascaris lumbricoides and hookworm species. The infection is transmitted through feco-oral route and can have significant impacts on the health of children, leading to delayed physical and cognitive development. Symptoms of trichuriasis include diarrhea, anemia, lack of protein energy, weight loss, headaches, and fever. Currently, there are no commercially available vaccines against whipworm infection, and preventive chemotherapy and good hygiene practices are important in controlling the disease. Trichuris trichiura eggs can be carried by the outer body surfaces of Musca domestica, the common housefly, potentially acting as mechanical vectors for spreading the infection. Population genomics studies have revealed the genetic structure and distribution of T. trichiura, supporting an African origin and subsequent translocation with human migration.
Why insect is important?4 answersInsects are important for several reasons. Firstly, they have been used in various civilizations for their medicinal properties, with compounds from insects being used to treat diseases such as rheumatism, arthritis, and cancer. Secondly, insects play a crucial role in ecosystems, forming an important part of every ecosystem and providing valuable ecosystem services. Additionally, insects can serve as a sustainable source of protein, which is particularly important for the growing population and low-income countries. However, the decrease in insect biomass and biodiversity is a concern due to factors such as agriculture, global warming, and anthropogenic impact. Overall, insects contribute to human health, ecosystem functioning, and sustainable food production.
How can Trichoderma be used to control plant diseases?5 answersTrichoderma can be used to control plant diseases through various mechanisms. It acts as a biocontrol agent by competing with pathogens, producing antibiotics, and parasitizing them. Trichoderma also promotes plant growth, improves nutrient utilization efficiency, and enhances plant resistance. It can induce plant systemic resistance and activate plant defense responses against biotic and abiotic stresses. Trichoderma-based formulations, either alone or in combination with other beneficial microbes, have been used to control and prevent plant diseases. The application of Trichoderma, along with bokashi fertilizer from agricultural waste, has been found to increase plant growth, production, and resistance to plant pathogens. Overall, Trichoderma offers a safe, low-cost, and eco-friendly approach to managing plant diseases and promoting sustainable agriculture.
What is the importance role of trichomes in the plants?5 answersTrichomes play important roles in plants. They serve as key functional traits that protect plants against abiotic stresses, herbivores, and pathogens. Trichomes also have ecological significance and can be used for species characterization and taxon delimitation. Additionally, trichomes are involved in water absorption and metal detoxication, which have implications for ecology, the environment, and agriculture. Trichomes are part of the plant's defense mechanisms against herbivores and can be indicators of plant defense. They can contribute to both herbicide and herbivory resistance, reducing plant injury. Trichomes on the lower leaf surface can directly decrease gas fluxes and indirectly increase leaf temperature, affecting photosynthetic rates and water-use efficiency. In summary, trichomes have diverse functions in plants, including protection against stresses, water absorption, metal detoxication, defense against herbivores, and influencing gas exchange and temperature regulation.
What are the implications of lipogenesis in Trichogrammatidae for the control of insect pests?5 answersLa lipogénesis en Trichogrammatidae tiene implicaciones para el control de plagas de insectos. Los trichogrammatidae son parasitoides de huevos que han sido estudiados por su uso potencial en el biocontrol de diversas plagas de cultivos. Estos parasitoides tienen la capacidad de sintetizar lípidos tanto durante su etapa larvaria como adulta. Los lípidos son críticos para la aptitud de un organismo, y la capacidad de Trichogrammatidae para sintetizar lípidos les permite transportar reservas sustanciales de lípidos de su huésped. Esta capacidad puede contribuir a su efectividad como agentes de biocontrol, ya que les proporciona reservas de energía para la supervivencia y reproducción. Adicionalmente, la lipogénesis en Trichogrammatidae puede desempeñar un papel en su adaptación a los estreses, como la exposición a pesticidas. En general, comprender las habilidades lipogénicas de Trichogrammatidae puede informar estrategias para utilizar estos parasitoides en el control de plagas de insectos en ecosistemas agrícolas.
