Laboratory cultures of field-collected larval tobacco budworm, Heliothis virescens (F.), beet army worm, Spodoptera exigua (Hübner), and fall armyworm, S. frugiperda (J. E. Smith) were bioassayed for response to three pyrethroids in combination with piperonyl butoxide (PBO), or MGK-264. The greatest synergistic effects were seen in S. exigua which also displayed the greatest tolerance to pyrethroids without synergists. The highest SR50 (synergist ratio) value for S. exigua was 22.1 with fenvalerate-PBO mixed in a ratio of 1:5, the highest for S. frugiperda was 4.6 with fenvalerate-MGK-264 1:5, and the highest for H. virescens was 1.3 with permethrin-MGK-264 1:5 or with fenvalerate-PBO 1:5.

Planting Season

Beet armyworm (Spodoptera exigua Hübner) (Lepidoptera: Noctuidae) is known to be a polyphagous insect that infests many crops such as welsh onion, maize, tobacco, cotton, and others. In Indonesia, this species is a major pest of shallot. The study was aimed to monitor the population of beet armyworm in the shallot plantation in Bantul Regency, Yogyakarta. The monitoring was conducted using pheromone traps containing Z-9-tetra decanol 10 µg/rubber unit and Z-9-tetradecadienyl 90 µg/rubber unit. The pheromone was placed in the fields to trap males during on- and off-shallot plant season. The sites for placing the pheromone traps were selected in the farms where shallot was planted once and twice per year. The selected sites were with shallot and non-shallot in their surrounding areas. The result showed that males emerged both on- and off-shallot planting seasons in most of the areas. The average number of trapped males during the shallot season was < 5 males/trap/week. The number increased and reached the peak (7.33 males/trap/week) in June until July which was the off-shallot season. The population reduced to < 2 males/trap/week at the end of second shallot planting season until end of the year where the fields were mostly planted with rice. These findings indicate that the beet armyworm presents all year around with or without shallot in the fields. It suggests that management of this insect should be done not only during the shallot season but also the remaining seasons to obtain more effectiveness.

The aim of this research is to gain further understanding of how particular insect species respons to different host plants. This research isconsidered as preliminary research in integrated pest management for Spodoptera exigua. We report herein the consumption and utilizationof green onion (Allium fistulosum), caisin (Brassica rapa subsp. Parachinensis) and celery (Apium graveolens) by Spodoptera exigua. Theevaluation of indices of food consumption, growth and food utilization showed that caisin (Brassica rapa subsp. Parachinensis) was the bestfood for the last instar larvae of S. exigua as compared with celery or green onion. Growth rates and efficiency of conversion of ingestedfood to biomass (ECI) were significantly higher for larvae fed caisin (11.93%) than for those given green onion (8.06%) or celery (7.74%)Although the protein content of caisin (2.23%) was a bit lower than that of green onion (2.45%) but higher than celery (1.28%), we suspectthat the larvae performed best in caisin due to good balance between protein and carbohydrate as well as water content in caisin as comparedwith other host plants.
