Next month will see the first major event in a new four-year project which promises to be the world's largest effort to monitor and promote awareness of moth populations. Moths Count (www.mothscount. org), launched this spring by wildlife television presenter David Attenborough is Britain's attempt to address the apparent decline in many of its numerous moth species. The launch attracted consid...

Nowadays, the use of carob (Ceratonia siliqua L.) is reduced to its seeds. In fact, food additive E410, locust bean gum, obtained from endosperm. However, available information regarding bioactive potential seeds limited and, often, with poorly established terminologies, not allowing reader know if studied samples included seedless or seeded samples. So, present study intended carry out a chemi...

In this study, we tested (1) whether non-North American gypsy moth strains are susceptible to North American isolates of Entomophaga maimaiga and (2) the potential for erosion in the efficacy of E. maimaiga in controlling gypsy moth. We used bioassays to assess the variability in virulence (measured as time to death) as well as fitness of the pathogen (measured as spore production) in four gyps...

Several application parameters of microencapsulated (MEC) sex pheromone formulations were manipulated to determine their impact on efficacy of disruption for codling moth, Cydia pomonella (L.); oriental fruit moth, Grapholita molesta (Busck); obliquebanded leafroller, Choristoneura rosaceana (Harris); and redbanded leafroller, Argyrotaenia velutinana (Walker). Depending on the experiment, the f...

An extract of a rotenone-containing plant yam bean, Pachyrhizus erosus (L.) Urban, seeds was tested against the diamondback moth, Plutella xylostella (L.) in a greenhouse to determine its potential as an oviposition deterrent and compared with coumarin and rutin, known as diamondback moth oviposition deterrent compounds, rotenone, and an extract of Peruvian cube root, at a concentration of 0.5%...

Pheromone traps can be used for evaluating the success of treatments that are applied to either eradicate or delay the growth of isolated low-density populations of the gypsy moth, Lymantria dispar (L.). We developed an index of treatment success, T, that measures the reduction in moth counts in the block treated adjusted by the change in moth counts in the reference area around it. This index ...

the codling moth, cydia pomonella, is the most important pest insect in apple orchards. efficacy of a native strain of the egg parasitoid wasp, trichogramma embryophagum, was statistically compared with chemical control and check treatments in an apple orchard. the best times for releasing the parasitoid wasps were determined by using a forecasting model based on estimation of growing degree ho...
