Abstract

Anagrus nilaparvatae (Pang et Wang) is an egg-parasitoid of rice brown planthopper (Nilaparvata lugens Stål). The objective of this study was to develop a mass-rearing technique of A. nilaparvatae. Mass-rearing was done using a plastic box (14 cm × 18.5 cm × 18.5 cm, made of plastic-mica, the upper side equipped with a 10 cm test tube), placed on a tray with rice seedlings containing an estimated of 11,130 eggs of N. lugens. About 355 adult parasitoids were successfully released per box when each box was infested with 50 parasitoids. The number of parasitoids produced were reduced to 164 adults when the infestation was made at 100 parasitoids per box. The emergence of parasitoids started around 07:00 am until 04:00 pm with the highest rate (36.2%) occured at 10:00 am. One plastic box cost only Rp10.000,-; thus the estimate cost to produce one parasitoid using this tecnique was Rp60,- These findings suggest that the plastik box is a simple and inexpensive technique for mass-rearing of A. nilaparvatae.

Abstract

Acid sulfate soil productivity is low due to the low availability of nutrients and high levels of soil acidity. It needs the organic material and dolomite to create the growing medium to be balance on its nutrient available, both physical and biological characteristic on the acid sulfated land. The aim of this research was to know the respond of cacao germ and the optimal doses of organic fertilizer of palm oil mill effluent. This research was take place in Jambi during September 2012 until March 2013. The factorial completely randomized design was applied. The first factor was organic fertilizer of palm oil mill effluent doses (0, 70, 140 and 280 ml.polybag-1 or equivalent with 0, 28.000, 56.000 and 84.000 l.ha-1). The second factor was dolomit doses (0, 2 and 4 g.polybag-1 or equivalent with 0, 800 and 1600 kg.ha-1). Kakao Lindak Klon ICS 13 was used as indicator plant. The acid sulfated soil was taken from Lagan Ulu Village Tanjung Jabung Timur District Jambi Province. The result of the research showed that the respond of cacao germ toward to an organic fertilizer of palm oil mill effluent and dolomite useness effected on the increasing of vegetative growth. Generally conclusions showed that the combination of 800 kg.ha-1 of dolomite and 84.000 l.ha-1 organic fertilizer of palm oil mill effluent was the optimal treatment which show the maximum of plant high, crown dry weigh, leaf wide and root crown ratio.

Abstract

Parasitoids are natural enemies of insect pests that can be used for biological pest control. Effective performance of parasitoid on the insect pest can be disrupted by the use of insecticides. This paper discussed the effect of insecticides on parasitoids, as well as the effect of deltamethrin insecticide on the behavior and biology of parasitoids. The effect of insecticides on parasitoids generally was studied by using sublethal dosage. Review of literatures indicated that deltamethrin insecticide disturbed parasitoids which affected the nervous system, and ultimately changed the behavior and biology of parasitoids. Inappropriate use of insecticide in the field reduced the ability of parasitoids in controlling insect pests.

Abstract

Host searching behaviour by a parasitoid includes orientation to the volatile compounds (odor) relesead by host or host plant. The aim of this study was to determine the changes in the orientation behaviour of Anagrus nilaparvatae (Pang et Wang), the egg parasitoid of rice brown planthoppers (Nilaparvata lugens (Stål)), after being exposed to sublethal concentrations of deltamethrin. The impact of residue on plants to the behaviour of parasitoid was also studied. The sublethal concentrations (LC10 and LC40) used were 0.023 ppm and 2.235 ppm, respectively. Deltamethrin applied to the rice plants were 12.5 ppm and 6.25 ppm, and its effect was observed at 3 hours, 1, 3 and 7 days after application. Orientation behavior was studied using Y-tube olfactometer. Application of deltamethrin at subletal concentration reduced the ability of surviving A. nilaparvatae to detect odors (volatile ompounds) released by the host, N. lugens. The higher the concentration of deltamethrin applied to the parasitoid or to the rice plants, the more prominent effect observed in the changing in the parasitoid behavious, in particular disruption to the parasitoid’s orientation to find their host. As consequences, effects of deltamethrin may lead to reduce the effectiveness of A. nilaparvatae as biological control agents in the field as a result of declining their searching capacity.
