Abstract

This study was aimed to investigate the population dynamics of the cabbage insect pests, Plutella xylostella and Crocidolomia pavonana under natural conditions. The population succession patterns of both pests were determined by observing the abundance of their population on a regular basis from the beginning to the end of the planting season. Understanding the population succession patterns of P. xylostella and C. pavonana will give an idea the shifting time by both pests on attacking the crops, therefore on deciding the time of controlling. The population succession patterns occur in 8 weeks of planting season. P. xylostella dominated the cabbage plants when they were 1-5 weeks after planting (WAP), but when the cabbage plants were more than 5 weeks old they were dominated by C pavonana.

Abstract

The influence of the population of Aphids on crops of great chili pepper (Capsicum annuum L.) Against The Harvest One of the obstacles in the cultivation of pepper plants is the presence of aphid pest attack. The purpose of this research is to know the influence of the population of aphids on crops of Chili with different age and influence pest aphids attack against crops plant chili. Moving on to the results was showing that aphid pests attacked chili plants at different ages. The attack was found since the 100plant was two weeks after planting (wap) with the amount of 45.1 tail. Peak attacks occur in plants four weeks after planting (wap) with a total of 175.0 tails. Furthermore, the attack was a decrease due to the age of the plant getting older. An aphids attack results in low yields. Observation on chili harvest was done only 2 times. The highest occurrence of pepper crops has the lowest average yield of 33.8 g and 38.2 g whereas, the lowest pest-infected pepper plant has the highest average yield of 52.33 g and 57.2 g.
