ABSTRACT
The effects of low temperatures on the fitness of Trichogrammatoidea
armigera Nagaraja (Hymenoptera: Trichogrammatidae). T. armigera is one of
the potential egg parasitoids. The aim of this research was to study the effects of
low temperatures ( 9ºC and 15ºC) on the fitness of T. armigera. The design of the
experiments is a factorial design with two factors (temperature and age of
parasitoid), with 10 replicates. Fitness were measured based on the survival,
fertility, size, sex ratio, lifespan and fecundity. Result showed that the emergence
of T. armigera was postponed by 2-5 days under low temperatures. Temperatures
had a more significant effect than age of parasitoid. The postponement of adult
emergence is very useful in regard to field application schedules. Percentage of
adults emergence, sex ratio, egg productivity, fecundity tended to decrease under
low temperatures, the length of female adult wings varied in each treatment and it
tended to be shorter in 9ºC, while the width of female adult heads was almost
similar in all treatment except in untreated control. These characters are very
important in determining the fitness of the parasitoid in the field.
KEY WORDS: Trichogrammatoidea armigera, egg parasitoid, temperature, fitness,
age.

Oviposition Deterrence of Bean Weevil, Callosobruchus chinensis L.(Coleoptera: Bruchidae) Treated with
Ten Plant Extracts. Pest and Diseases attack agricultural products not only in the field but also in
storehouse. Their attack causes decreasing both quantity and quality of stored materials. One of
important stored product insect pests is Callosobruchus chinensis L. (Coleoptera: Bruchidae). Till now
the effective strategy to control this insect pest is chemical control by using synthetic insecticides. The
improper use synthetic insecticides causes some undesirable effects, so alternative strategist should be
searched to controls insect pests in storehouse. One of the alternatives is by using plant materials as
insect pests control agent. The aim of this study was to find out the oviposition deterrence of C.
chinensis treated with ten plant which were extracted with methanol, hexane and ether. Oviposition
deterrence was evaluated by choice and nochoice methods at 1,3 and 5% of extract concentration.
Extract of Acorus calamus (methanol), A.calamus (hexane), A. calamus (ether), Illicium verum (ether),
Pogostemon calbin (hexane), P. cablin (ether), Vetiveria zizanioides (hexane), and V. zizanioides (ether)
were able to deter ovipostion activity of C. chinensis by more than 90% of deterrence. Further study
should be conducted to isolate and identify the active compound and to make botanical insecticide
formulation for practical use as a commercial product.
