ABSTRACT Helicoverpa armigera is one of the important pests in maize in Gorontalo province. The study aims to determine the population of corn cob borer Helicoverpa armigera has been implemented in Bolango Bone regency, Gorontalo Province from March to June 2011 study used a survey method based on the four zoning districts as follows: (1) the northern region districts Tilong Kabila, (2 ) Suwawa Western region districts namely, (3) the Eastern region districts Kabila, and (4) the South region, namely districts Bone Pante. The results showed that the average population of H. armigera cob borers on maize in Bone regency Bolango highest in the district is 3.75 Kabila Bone tail, then the tail 1.92 Tilongkabila districts, sub-districts and districts tail Kabila 1.83 Suwawa 1,4 tail.

Monitoring of chickpea pod-borer, Helicoverpa armigera (Hb.) and its acvities throughtout the year was studied by installing pheromone traps at Pulses Research Center, Ishurdi, Pabna during January 2004 to December 2006. Pod-borer moth catching in pheromone traps was started between 3rd weeks of January to 2nd weeks of February depending on the climatic conditions of the year. Catching of moths was increased gradually and reached its pesk in the month of April then gradually decreased and diminished to zero in the last week of July and ultimately remained zero upto December. Integrated Pest Management Programme against chickpea podborer should be initiated from mid-January to manage this pest population very effectively.

Refuge Areas

ABSTRACT: Natural biological control is one of the major causes responsible for reduction of pest population in agricultural ecosystem. However, natural biological control importance is usually minimized by not being estimated. This study reports the occurrence of Campoletis sonorensis (Cameron, 1886) (Hymenoptera: Ichneumonidae), Archytas marmoratus (Townsend, 1915) and Archytas incertus (Macquart, 1851) (Diptera: Tachinidae) associated with Helicoverpa armigera (Hübner, 1809) (Lepidoptera: Noctuidae). The rate of larval parasitism was up to 41% in structured refuge areas of cotton, without chemical control with insecticides. This study strengthens our knowledge relating to parasitoids associated with natural control of H. armigera in the American continent. In addition, it documents the rule that structured refuge areas could play as a source of natural enemies, besides their contribution to production of non-selective populations to Bt technology.

Experimental Plots

AbstractSmallholder crops (sunflower, maize, sorghum and cotton) were grown in experimental plots at seven sites, representing different agricultural zones of Kenya, over four seasons. Helicoverpa armigera (Hübner) (formerly Heliothis armigera) only occasionally achieved population densities sufficient to cause obvious damage to the crops, and was virtually absent from the coastal sites. At the inland sites, infestation and mortality levels varied greatly. Information is presented on the incidence of H. armigera, and the identity, distribution and frequency of its common parasitoids and (potential) predators, sampled in the experimental plots. Trichogrammatoidea spp., egg parasitoids, and Linnaemya longirostris (Macquart), a tachinid late-larval parasitoid, were the most common parasitoid species, but total percentage parasitism was rather low. Of the large complex of predators, only anthocorids and ants (predominantly Pheidole spp., Myrmicaria spp. and Camponotus spp.) were sufficiently common and widespread to be of importance in suppressing H. armigera. The abundance of predators fluctuated widely between sites, but anthocorids were most abundant at the western sites.
