- Both reproductive and legislative control methods play important role in insect pest management. Explain your answer with relevant examples from different countries.Respond to the following statements in reference to the five kinds of species interactions listed below. An example of this interaction is that between an epiphyte and its host. In this interaction between two species, both species are harmed to some degree. In this interaction, both species benefit. In this interaction, one individual or species is usually killed while the other benefits by eating it. In this interaction, one species is harmed but usually not killed, to the benefit of the other that lives on or in it. a. Competition b. Predation C. Mutualism d. Commensalism e. ParasitismANSWER THE FOLLOWING: If you are to engage into aquaculture, how will you do it considering your current location and available resources. What species, level of management and culture system will you consider? (imagine your location is Philippines) On the otherhand, if all resources are available and favorable, what brackishwater and marine species will you grow/culture? Discuss your criteria of considering these species. Describe the level of management and culture system that you will employ.

How integrated Pest Management (IPM) keep pest population low without economic loss? Please elaborate your answer wherever needed.
- A description of an invasive species should include which characteristic(s)? nonnative easily controlled or removed poor competitor causes damageforest sites than in forest fragments, whereas there were no significant differences between fragments of different sizes. These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.Pest and diseases are the main cause for decreased crop yield; can you elaborate some important measures to control these organisms? Support your answer by considering all the possibilities of pest prevalence and their control please please answer that
- Background: An area has two different Anopheles species, species A and species B. Both can vector Plasmodium, although Plasmodium develops best and is transmitted best by species B. Species A is dominant because its larvae outcompete species B in the main shared breeding sites, small lakes, and ponds. Therefore the population of B is currently small. The small lakes and ponds are also the source for the main food source in the region, fish, grown in fish farms. There is grazing land, but other than chickens, the local population does not have livestock. Species A is largely endophilic, species B is exophilic. In other localities, species A and B will also feed on cattle, and B appears to prefer cattle. Both species like to roost during the hot day in rock overhangs and small caves. The national malaria control agency sends in a new person to develop a malarial control strategy. (S)he recommends draining the lakes and ponds, and intensive house spraying. Discuss the pros and cons of…Choose the type of symbiotic relationships with their correct definitions. The 4 options are: mutualism, commensalism, parasitism or none of the above. Please explain in details why each option was selected.Definitions: One species kept alive to benefit the other species Both species benefit from forming a symbiotic relationship Neither of the species benefit from forming a symbiotic relationship While one species increases its survivability, the other species neither benefits nor suffers from the symbiotic relationship One species benefits greatly while the other species diesBackground: An area has two different Anopheles species, species A and species B.
