Polyphagy and primary host plants: oviposition preference versus larval performance in the lepidopteran pest Helicoverpa armigera
Oviposition preference and several measures of offspring performance of Helicoverpa armigera (Hübner) were investigated on a subset of its host plants that were selected for their reputed importance in the field in Australia. They included cotton, pigeon pea, sweet corn, mungbean, bean and common sowthistle. Plants were at their flowering stage when presented to gravid female moths. Flowering ...

Hairy Vetch management for no-till organic corn production
Rolling-crimping to control hairy vetch (Vicia villosa Roth) may make organic no-till corn (Zea mays L.) possible. This study investigated how rolling-crimping date and growth stage of the cover crop affected hairy vetch control and if a rolled-crimped hairy vetch cover crop could supply weed control for no-till corn. Hairy vetch was planted in late August and was rolled and crimped and planted ...

Effects of the herbicide dicamba on non‐target plants and pollinator visitation
Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

Could traditional plants hold the secret to saving crops from pests?
Researchers build on age-old practices to reduce food loss in Africa Without any effort at all, Hawa Saidi Ibura crushes dried beans, one at a time, between her fingers outside her home in Endagaw, a village in northern Tanzania. She’s holding a basket of a type of red bean eaten all over East Africa, but these beans are skeletons of what they once were. She harvested them from her farm ...

Influence of synchronization between adult emergence and host plant phenology on the population density of Pseudasphondylia neolitseae (Diptera: Cecidomyiidae) inducing leaf galls on Neolitsea sericea (Lauraceae)
Synchronization between the appearance of herbivorous insects and their host-plant phenology is a critical event, especially for short-lived insects such as gall midges. We studied a natural population of Pseudasphondylia neolitseae (Diptera: Cecidomyiidae) that induces leaf galls on Neolitsea sericea (Lauraceae) to evaluate the effect of synchronization on gall density in the subsequent ...

Why buy modern organic fertilizer processing machine
The traditional artificial composting is not suitable for the development of modern agriculture. The simple composting method has a long time to treat livestock manure, a low content of organic fertilizer nutrients and a slow release. After years of development, modern organic fertilizer production machine has become the development trend of organic fertilizer production in the future. The ...

Inheritance of resistance to the Soybean aphid in Soybean PI 200538
The soybean aphid (Aphis glycines Matsumura) is a major soybean [Glycine max (L.) Merr.] insect pest. Soybean plant introduction (PI) 200538 has strong resistance to the aphid. The objectives of our research were to determine the inheritance of resistance and to map gene(s) controlling resistance in PI 200538. F2 populations developed from crosses between PI 200538 and three susceptible genotypes ...

Nitrogen Fixers
Here’s a bit of geeky plant science. On this image of the roots of white clover, you can plainly see bumps along the roots that are called nodules. Over millions of years, the plant has evolved a symbiotic relationship with certain species of soil-dwelling bacteria called Rhizobia. This group of bacteria has the ability to take nitrogen from the atmosphere and “fix” it by ...
