| Although these fruit flies are polyphagous, they typically show strong seasonal preferences for certain fruits. |
|
| While monophagous herbivores were typically found at lower densities in polycultures, polyphagous herbivores showed a more variable response. |
|
| The larvae, which normally are polyphagous and hunt several aphid species, live in trees and shrubs. |
|
| But as a tropical and polyphagous species, it could present a risk to protected ornamental and vegetable crops. |
|
| Control by crop rotation is limited by the polyphagous habit of some races of D. dipsaci and by persistence of the nematode in clay soils. |
|
| This highly polyphagous species can cause damage, especially in areas where it has newly been introduced. |
|
| Their function as polyphagous predators within orchards was recognized in the 1800's, and several species are known to prey on key tree fruit pests. |
|
| Bemisia tabaci: the species is polyphagous, particularly the B biotype which has spread in the greater part of tropical regions. |
|
| This polyphagous species is widely distributed in the Palearctic region and appears to have colonized South and North America within the last several decades. |
|
| Organism that develops on more than one host, eg, the gypsy moth, a polyphagous caterpillar feeds on both deciduous and coniferous trees. |
|
| A danger for many omnivorous or polyphagous species is that potential food items may be poisonous. |
|
| The Greenfly is one of the most common pests in our country, as it is a species with a wide variety of genres, some of them attack a single species of plant and others are more polyphagous. |
|
| In other countries, A. gossypii is a major pest of cotton and cucurbits, and is also extremely polyphagous attacking a wide range of field and glasshouse crops throughout the world. |
|
| Many are restricted to feeding on one species of plant, while others are polyphagous. |
|
| Paradoxically, this thrips is not polyphagous in its incursive range. |
|
| However, these thripids are polyphagous feeders, breeding in many unrelated plant species. |
|
| The two-spotted spider mite, Tetranychus urticae Koch, is an extremely polyphagous pest. |
|
| Two-spotted spider mite, Tetranychus urticae Koch, is a polyphagous, parenchyma cell feeding spider mite with over 200 host plant species. |
|
| In the polyphagous species, deterrent compounds are less important in the interpretation of information by the central nervous than is true for selective feeders. |
|
| It is highly polyphagous and can attack most conifers and hardwoods. |
|
|
|
| The authors noted that populations of this polyphagous species, collected from cucumber and chrysanthemum in glasshouses in the Netherlands, behave as genetically distinct host races. |
|
| Although the list of host plants is not exhaustive, these results confirm that B. invadens is a polyphagous pest which threatens important crops such as mangoes and bananas in Kenya. |
|
| Plant diseases caused by the soil-borne fungal pathogens Sclerotinia sclerotiorum and S. minor are undeniably cosmopolitan and highly polyphagous. |
|
| This polyphagous insect also feeds on conifers. |
|
| But aleyrodid pests of agricultural crops are usually highly polyphagous, and a good portion of aleyrodids on palms come from their ranks. |
|
| Drought-stressed trees are more vulnerable to pests such as the polyphagous shot hole borer, which is killing trees via fungal infection throughout Southern California. |
|
| The polyphagous Mediterranean fruit fly Ceratitis capitata damages more than 250 different types of fruit including citrus as well as many deciduous and subtropical fruits. |
