ERRO, HARLENE N. Population Dynamics of Coffee Insect Pests and their Natural Enemies in Amadeo, Cavite. Undergraduate Thesis. Bachelor of Science in Agriculture Major in Crop Science. Cavite State University, Indang Cavite. June 2019. Adviser: Dr. Evelyn O. Singson<br/><br/>The study was conducted from June to December 2018 in a coffee farm located at Dagatan, Amadeo, Cavite, to assess the population dynamics of coffee insect pests and their natural enemies. Specifically, the study aimed to: (1) identify the coffee insect pests observed in the coffee farm; (2) identify the natural enemies associated with the insect pests of coffee; (3) determine the incidence of coffee insect pests; (4) determine the infestation rate of coffee insect pests; and (5) distinguish the factors affecting the population dynamics of the insects in the coffee farm.<br/><br/>This study is a descriptive type of research. Visual observation, recording, collection and preservation of insects found from the top, middle and bottom portion of the 30 sample trees located in the area were done to gather relevant data for the study. Data gathering was done every morning, and once a week for six months.<br/><br/>Twenty-three insect pests which belong to the insect order Coleoptera, Diptera, Hymenoptera, Hemiptera and Homoptera were collected from the study site. In addition, ten natural enemies which belong to the orders Coleoptera, Hymenoptera, Neuroptera, Mantodea and Arachnida (order Araneae) were encountered in the study site. The most notable natural enemy identified is the mealybug destroyer larvae which feeds on green coffee scale and green lacewings which predates on leafhoppers and green coffee scale. On the other hand, the green coffee scale has the highest pest incidence and highest infestation rate.<br/><br/>The population of insect pests showed an increasing trend from June to September which decreased thereafter. Temperature and relative humidity appear to have no significant effect on the pest population. On the other hand, the population of natural enemies increased in June and July which then decreased the following month. The<br/>temperature but not relative humidity reveals to have a significant effect on their reproduction. However, there are other factors such as elevation and rainfall that must be considered to truly determine the population dynamics of coffee insect pests and natural enemies in Amadeo, Cavite.<br/> |
