grape berry moth, lobesia botrana (denis and schiff.) is a destructive pest of grapevine in orumieh (northwest, iran) vineyards. it is mainly controled through application of broad-spectrum insecticides, which can adversely affect vineyard ecosystem and consequently human health. since a first step in setting up an ipm program is to assess the biological control agents within the ecosystem, so ...

factors hindering the development of inundative biological control are insect rearing costs and provide an adequate amount of natural enemies at the appropriate time. storage of natural enemies is a useful technique to increase time flexibility of parasitoids production, and coincide the natural enemies release with pest outbreaks period, and also could reduce costs of mass production. another ...

Apocephalus paraponerae (Diptera: Phoridae) parasitizes workers of the giant tropical ant, Paraponera clavata (Hymenoptera: Formicidae), in Central America. When female parasitoids locate fighting or injured workers of this species, they deposit one or more eggs in them and feed from wounds. Male parasitoids are also attracted to hosts for feeding and to locate females for mating. In a series o...

Native predators and parasitoids were identified against the invasive whiteflies in cotton ecosystem. Over past several decades, its control has been increasingly based on use of natural enemies. The enemies include Cheilomenes sexmaculata, Chrysoperla carnea, Diadiplosis sp, Orius insidiosus, two coleopteran beetles, Cybocephalus nipponicus, Delphastus catalinae species Aphelinidae parasitoids...

Beginning in 1993, Florida’s citrus industry has been invaded by citrus leafminer (Phyllocnistis citrella Stainton, Lepidoptera: Gracillariidae), brown citrus aphid (Toxoptera citricida Kirkaldy, Homoptera: Aphididae), and the Asian citrus psylla (Diaphorina citri Kuwayama, Homoptera: Psyllidae). The source(s) of these pests remain unknown but other countries in the Caribbean, as well as Centra...

We report here the use of a specific beta-galactosidase staining assay and Northern blotting technique to examine the expression of three genes encoding either antibacterial peptides (diptericin, cecropin A) or an antifungal peptide (drosomycin) in Drosophila following infection by larval and pupal parasitoids. The results show that the genes encoding these peptides are either not induced or mi...

This study determined the species of parasitoids associated with Chrysomya megacephala, collected on bovine kidney baits, in Itumbiara, State of Goias, Brazil. The pupae were obtained by flotation. They were individually placed in gelatin capsules until the emergence of the adult flies or their parasitoids. The overall prevalence of parasitism was 18.6%. Brachymeria podagrica, Nasonia vitripenn...

The functional response of the parasitoid Dinarmus basalis (Rond.) (Hymenoptera: Pteromalidae) is determined to evaluate its potential as a biological control agent. Four female wasps in the presence of males parasitoids, were allowed to oviposit during their life span or hosts at different densities. The data were fit by Rogers′ (1972) parasitoid model. The rate of parasitoid search was a′= 0....

Abstract Background The diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a serious and economically important pest of crucifers in Delhi, India. Larvae pupae the were collected from cabbage, cauliflower broccoli crops grown vegetable fields at farm ICAR-Indian Agricultural Research Institute (ICAR-IARI), New Delhi-110012, December 2021 to June 2022. larvae transfe...
