Efforts to maximise crop yields are fuelling agricultural intensification, exacerbating the biodiversity crisis. Low-intensity agricultural practices, however, may not sacrifice yields if they support biodiversity-driven ecosystem services. We quantified the value native predators provide to farmers by consuming coffee's most damaging insect pest, the coffee berry borer beetle (Hypothenemus ham...

Cohorts of emerald ash borer larvae, Agrilus planipennis Fairmaire, were experimentally established in July of 2008 on healthy green ash (Fraxinus pennsylvanica) trees in two wooded plots at each of three sites near Lansing, MI, by caging gravid emerald ash borer females or placing laboratory-reared eggs on trunks (0.5-2 m above the ground) of selected trees. One plot at each site was randomly ...

Twenty-three coffee (Coffea arabica) genotypes were evaluated for relative resistance against white stem borer (Xylotrechus quadripes) and leaf rust (Hemileia vastatrix) at Horticulture Research Station, Malepatan, Pokhara during three consecutive years from 2016 to 2019. The monthly observation on the emergence of this showed that "Yellow caturra" “Tekisic” highly infested with as compared oth...

The parasitic nematode Metaparasitylenchus hypothenemi (Tylenchida: Allantonematidae) was first reported infecting the coffee berry borer (Hypothenemus hampei (Ferrari); Coleoptera: Curculionidae: Scolytinae) in coffee plantations of Chiapas, Mexico (Castillo, Infante, Barrera, Carta, & Vega, 2002), and was later described as a new species (Poinar, Vega, Castillo, Chavez, & Infante, 2004). This...

The sugarcane borer, Diatraea saccharalis (F.) (Lepidoptera: Crambidae), is the key insect pest of sugarcane, Saccharum spp., grown in Louisiana. For more than 40 years, Louisiana sugarcane farmers have used a value of 10% internodes bored at harvest as the economic injury level (EIL). Three plant-cane studies were conducted to re-evaluate the long-standing sugarcane borer EIL level using the m...

Southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera: Crambidae), is a major insect pest of corn, Zea mays L., in the southern United States. Germplasm lines with resistance to southwestern corn borer have been developed and released by the USDA-ARS. Two single-cross hybrids produced by crossing germplasm lines with resistance to southwestern corn borer and a susceptible single-cros...

The parasitoid Prorops nasutaWaterston (Hymenoptera: Bethylidae) is a wasp of the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae). In this study, the attractiveness of different volatiles to P. nasuta was studied in the laboratory using a Y-tube olfactometer. Female wasps were attracted to coffee berry borer-infested coffee berries but not to uninfested or artiÞcia...

telenomus beneficiens is a common egg parasitoid of sugarcane top borer scirpophaga excerptalis; however, in winter time the incidence of the parasitoid on top borer eggs is extremely low. t. beneficiens adults were released at various time durations into sugarcane plots to evaluate the parasitic potentiality of the parasitoid against sugarcane top-borer. the egg parasitoid t. beneficiens of su...

Laboratory studies was conducted to investigate effect of mating behavior on egg laying, host selection and competition with Bracon hebetor. The results showed that no differences in laying between mated unmated females. number were 90.67 per female females respectively. However produce only males progeny.The parasitoid response the larvae different lepidopterous insects such as. Mediterranean ...

Biodiversity loss will likely have surprising and dramatic consequences for human wellbeing. Identifying species that benefit society represents a critical first step towards predicting the consequences of biodiversity loss. Though natural predators prevent billions of dollars in agricultural pest damage annually, characterizing which predators consume pests has proven challenging. Emerging mol...
