Studies on potential adverse effects of genetically engineered crops are part of an environmental risk assessment that is required prior to the commercial release of these crops. Of particular concern are non-target organisms (NTOs) that provide important ecosystem services. Here, we report on studies conducted in the Philippines over three cropping seasons with Bt eggplants expressing Cry1Ac f...

Arthropod pests are among the biggest problems faced in tomato production worldwide. To overcome losses caused by these pests, one of most sustainable and economical strategies is use resistance introgressed from wild species. We aimed to develop BC3F2 genotypes with high levels zingiberene (ZGB) whitefly (Bemisia tabaci biotype B), South American pinworm (Tuta absoluta), two-spotted spider mit...

In a two-year study, aqueous seed extracts of the neem tree Azadirachta indica A. Juss (Meliaceae) and Bacillus thurigiensis (Bt) were evaluated in the field for the management of pests of okra, Abelmoschus esculentus (L.) Moench. The aqueous neem seed extracts were applied at the rate of 30, 50, 75 and 100 g/l and B.thurigiensis was applied at the rate 1.0 g/l of water. Actellic 25 EC, a synth...

Riparian vegetation habitats in irrigation canals provide various ecosystem regulatory services for human life, one of them was providing natural enemies agricultural pests. This study aims to analyze the abundance at paddy field, then figure out interaction between riparian and based on four different locations tertiary Slamet Village. Arthropods were observed by visual control yellow pan trap...

Research here explored the use of controlled atmospheres (CA) for managing arthropod pests that infest dry-cured hams. Experiments were conducted with low oxygen (O₂) achieved with low pressure under a vacuum, high carbon dioxide (CO₂), and ozone (O₃). Results showed that both low O₂ and high CO₂ levels required exposures up to 144 h to kill 100% of all stages of red-legged ham beetle, Necrobia...

Irrigated almond orchards in Spain are increasing acreage, and it is pertinent to study the effect of deficit irrigation on presence pests, plant damage, other arthropod communities. In an orchard examined from 2017 2020, arthropods diseases were studied by visual sampling under two treatments (T1, control T2, regulated (RDI)). Univariate analysis showed no influence aphid Hyalopterus amygdali ...

Generalist predators are widely acknowledged to contribute valuable levels of biological control in agroecosystems throughout the world. Although their feeding habits can result in the rejection of target pests in favor of preferred and often more nutritious non-pest prey, these natural enemies are capable of colonizing habitats prior to the arrival of pests by subsisting on alternative sources...

background: laboratory bred sand flies are essential for the study of different biological phenomena including the transmis­sion dynamics of leishmania . the aim of the study was to determine the suitable situation for colonization and main­tenance of iranian strain of phlebotomus papatasi at laboratory conditions from an endemic focus of cutaneous leishmani­asis due to leishmania major . metho...

We hypothesize that biological diversification across ecological, spatial, and temporal scales maintains and regenerates the ecosystem services that provide critical inputs—such as maintenance of soil quality, nitrogen fixation, pollination, and pest control—to agriculture. Agrobiodiversity is sustained by diversified farming practices and it also supplies multiple ecosystem services to agricul...
