Oviposition is surely not far off since the first eggs are usually seen by mid-March. So it’s not too soon to start planning for early season control measures.

Management recommendations fo r pear psylla emphasize control of the overwintered generation or immature off-spring of the overwintered generation (Westigard & Zwick, ), as this prevents potentially severe problems later in the growing season. Thus, it is important to understand biology of the post-diapause winterform, and a great deal.

For interiorscape pest management, inundative release of adults is the most common use of coccinellids.

Because the life stages of a species can show differential response to the same pesticide (Banken and Stark ), we screened some commonly used biorational insecticides with adult coccinellids to best reflect current by: Potential of intercropping pesticidal plants with common bean in promoting natural enemies for pest management in agroecosystems.

Although it is difficult to classify this species as a key or secondary pest (depending on its status in different areas and local natural-enemy abundance), it is usually a secondary, indirect pest of pears.

In Belgium, two cultivation methods of pear are widely applied, namely organic farming and integrated pest management (IPM).

Abstract. Thirteen pear, Pyrus spp., cultivars were evaluated under field and laboratory conditions for resistance to Cacopsylla pyri (L.). In field studies, population growth was quantified over a I–mo period of development.

In the laboratory, the mode of host resistance was investigated by estimating oviposition and by:   4) Pear psylla is a major insect pest of pear production in the U.S.
