Abstract

The Potential of Predator Coccinella transversalis Fabricius (Coleoptera: Coccinellidae) as A Biology Control Agent Thrips parvispinus Karny (Thysanoptera: Thripidae) in Chili Plant (Capsicum annuum L.)Thrips parvispinus Karny (Thysanoptera: Thripidae) is one of the main pests in the cultivation of chili. T. parvispinus existence can damage chili plants and decrease production. This study aims to determine the potential of predator Coccinella transversalis required predation testing which includes a value of searching time (a), handling time (Th) and functional response C. transversalis to T. parvispinus on chili plants. The prey densities presented were 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 and 22 individuals. The exposure is done for twelve hours. Predator C. transversalis used is a female imago that has been fasted for 24 hours. The determination of functional response type was analyzed by regression analysis, while the predation rate is analyzed using Holling formula. The results showed that the prey density affects the predation rate and the functional response type C. Transversalis. The rate of C. transversalis predation is significantly different in each number of prey exposed. Similarly, on the basis of regression analysis, it is shown that C. transversalis has a functional response of type I to T. parvispinus prey. These results indicate that C. transversalis has potential as a biological control agent.

Abstract

Flight Activities and Population Development of Thrips parvispinus Karny (Thysanoptera: Thripidae) on Chili (Capsicum annuum L.). Thrips parvispinus Karny (Thysanoptera: Thripidae) is one of the main pests on chili. T. parvispinus attacked the leaves and flowers on chili. The behavior of its attacked fluctuate between morning until late afternoon since the plants grow in the field. The purpose of this research was to know the flight activity of T. parvispinus and its population development on leaf and flower of chilli plant. The research used survey method with direct observation on plants in the field. Flight activity of T. parvispinus was measured by using a yellow sticky trap placed diagonally on the plant. The results showed that daily flight activity of adult T. parvispinus fluctuated between morning, afternoon, and evening. The highest flight activity of adult occurred at 09.00-10.00 (39.81 adults) and the lowest was at 18.00-19.00 (9.84 adults). The population of T. parvispinus nymph was more than adult in the leaf. The highest population of nymphs occurred at 12.00-13.00 (21.07 nymphs). While the population of T. parvispinus adul was more on flower than nymph population. The highest adult population occurred at 18.00-19.00 (27.36 adults). There were strong indications that the nymph stadium frevers live on the part of the leaf than the flower, while the adult prefers the flower rather than the leaf.
