Intensive soil tillage and the resulting erosion constitutes one of main problems in olive growing. Palliative practices such as implementing vegetable covers are encouraged. Recently, method adding inert green roofs to soil, either alone or combination with adventitious vegetation, has stood out. Assessing this agronomic measure is our objective. This research was conducted 2022 Jaén province ...

Abstract Climates around the world are rapidly turning warmer and often drier. Agricultural approaches must change accordingly. One important global practice is commercial use of cryptic species Chrysoperla carnea-group green lacewings to control arthropod pests. Recently, one highly drought-tolerant species, originally present only in Old World, suspected expanding its range some driest habita...

Chlorpyrifos, lambda-cyhalothrin, cypermethrin, spinosad and buprofezin were tested against the second instar larvae and adults (except buprofezin) of the green lacewing, Chrysoperla carnea. The results showed that chlorpyrifos was more toxic to second instar larvae than lambda-cyhalothrin, cypermethrin, spinosad and buprofezin with LC50 values of 1.78, 8.81, 26.9, 294.36 and 997.05 ppm respect...

The pleasing lacewing genus Dilar Rambur is a dominant group of the family Dilaridae in Asia and is diverse in China with 18 described species. Herein we record five species of Dilar. Three species, i.e. Dilar hastatus sp.nov., Dilar spectabilis sp.nov. and Dilar taibaishanus sp.nov. are described as new to science. Dilar sinicus Nakahara and Dilar septentrionalis Navás are also redescribed. A ...

Seasonal occurrence of aphids and aphidophagous insects was monitored for six years (2006 2011) from full leaf expansion in May to leaf fall in October variety pecan trees that were not treated with insecticides. Aphid outbreaks occurred two times per season, once in the spring and again in the late summer. Yellow pecan and blackmargined aphids exceeded the recommended treatment thresholds one ...
