Searching and Feeding Behavior of Nephaspis oculatus and Delphastus catalinae (Coleoptera: Coccinellidae), Predators of Bemisia argentifolii (Homoptera: Aleyrodidae)
The coccinellids Nephaspis oculatus (Blatchley) and Delphastus catalinae (LeConte) [formerly D. pusillus (LeConte)] are predators of whiteßies (Homoptera: Aleyrodidae), and have shown potential for biological control of Bemisia argentifolii Bellows & Perring in greenhouses. We observed the searching and feeding behavior of N. oculatus and D. catalinae on hibiscus (Hibiscus rosa-sinensis L.). D....
متن کاملDistribution and Sampling of Bemisia argentifolii (Homoptera: Aleyrodidae) and Eretmocerus eremicus (Hymenoptera: Aphelinidae) on Cantaloupe Vines
Studies were conducted to examine the spatial distribution of immature Bemisia argentifolii Bellows & Perring and immature Eretmocerus eremicus Rose & Zolnerowich on cantaloupe vines and to develop efÞcient sampling plans. More B. argentifolii eggs were found on the 3rd leaf from the terminal of a cantaloupe vine than on any other leaf. The density of whiteßy nymphs peaked at leaf position 8, w...
متن کاملLife Table Analysis for Immatures and Female Adults of the Predatory Beetle, Delphastus catalinae, Feeding on Whiteflies Under Three Constant Temperatures
Immature development and reproductive life history of Delphastus catalinae (Horn) (Coleoptera: Coccinellidae) feeding on Bemisia tabaci biotype B (Gennadius) (Homoptera: Aleyrodidae) (= B. argentifolii Bellows and Perring) immatures was studied at three constant temperatures: 22, 26 and 30 degrees C. Lower developmental threshold temperatures (T0) were estimated at 9 and 9.9 degrees C, for male...

متن کاملLife tables and development of Bemisia argentifolii (Homoptera: Aleyrodidae) at different temperatures.
The life history of Bemisia argentifolii Bellows & Perring (Homoptera: Aleyrodidae) on tomato (Lycopersicum spp.) was studied based on the age-stage, two-sex life table at 15, 20, 25, 28, 30, and 35 degrees C. The intrinsic rate of increase (r) at these temperatures is -0.0176, 0.0667, 0.1469, 0.1611, 0.1745, and 0.0989 d(-1), respectively. The relationship among the gross reproductive rate (GR...
