Abstract

Trichogramma nana is one species of egg parasitoids that are polifag. insect pests that attack crops such as soybean pod borer and rice. Research conducted at the Laboratory of Entomology Research Institute for Tobacco and Fiber Crops Malang in March until June 2009 that aims to determine the reproductive capacity of T. nana on eggs  C. cephalonica. Reproductive capacity of T. nana allegedly using the net reproductive rate (Ro), estimatedtime of one generation (T), the capacity of population growth (r), and the rate of parasitoids per day (λ). T. nana were tested  came from the rice stem borer  eggs collected from the land in the district of East Java Beji Pasuruan. Eggs C.cephalonica which is used as the host is the result of breeding in the laboratory of Entomology Research Institute for Tobacco and Fiber Crops. The results showed that T. nana has greatpotential  as  biological agents.  Most  female  progeny  produced by adult females aged 1-2 days . On the first day produced 12 and 8 tails on the second day or 40% and 27% of the total of 30 females produced by a female during life.  Reproductive capacity of  T. nana on eggs C. cephalonica the net reproductive rate  Ro) = 44.7, Capacity of population growth (r) = 1.78,  parasitoid growth rate per day (λ)=5.9, and mean - mean length of generation (T) = 10, 9 days.

Abstract

Helicoverpa armigera Hubner is an insect pest of corn and cotton crops. Eggs are laid by  H. armigera imago on corn silk and cotton crops often have high mortality, mainly caused by egg parasitoid. H. armigera egg on various agroecosystem reported can  be parasited by at least 12 species of  Trichogrammatidae. The purpose of this study was to determine the diversity of  Trichogrammatidae family as  parasitoid eggs of  H. armigera on  low population. H. armigera egg sample taken from Asembagus, Lamongan and Blora at 1 m2 field  both monoculture and intercropping. Observation of parasitoids and predators  done at the Laboratory of Biological Control Balittas Malang. Parasitoid that appears preserved in the Hoyer medium for identification purposes. low population of  H. armigera Egg in Asembagus is  4 eggs/m2 in both monoculture maize and intercropping with 86-100 days after transplanting (DAT) cotton and  4.5 egg/m2 on cotton monoculture and intercropping with 75  DAT soybean, while 2 eggs/m2 in the Lamongan and Blora corn agroecosystem. The dominant egg parasitoid in Asembagus is T. chilotraea, as well as in Lamongan and Blora.
