The members of Coccinellidae are among the most important biological control agents being used throughout the world. The objective of this study was to provide the current scenario of this family in Saudi Arabia. Collection surveys of ladybird individuals were conducted throughout Saudi Arabia. A total of 5400 specimens of Coccinellidae were collected belonging to 51 species in 19 genera and seven tribes: Sticholotidini (2 genera / 10 species), Coccidulini (1/3), Scymnini (4/24), Diomini (1/1), Hyperaspidini (1/3), Chilocorini (3/8), Noviini (1/3), Coccinellini (8/11), Epilachnini (2/2). One genus, Clitostethus, and eight species and subspecies, Cheilomenes lunata lunata (Fabricius, 1775), Clitostethus arcuatus (Rossi, 1794), Nephus ornatulus Korschefsky, 1931, N. nigricans (Weise, 1879), Pharoscymnus fleischeri (Weise, 1883), Novius yemenensis Raimundo & Fürsch, 2006, Scymnus (Scymnus) scapuliferus Mulsant, 1850, and Stethorus endrodyi Fürsch, 1970, are reported as new records to Saudi Arabia. Two endemic species, Scymnus agrumi and S. arabicus, were recorded. This study also describes the geographical distribution for each species and the diagnostic characters for new records.

El objetivo del presente estudio fue determinar el ciclo, parámetros biológicos y descripción morfológica de Clitostethus arcuatus (Rossi), depredador de Siphoninus phillyreae (Haliday). Para la obtención de presas, se infestaron plantones de olivo con S. phillyreae colectado de olivares en Tacna. En el laboratorio, los diferentes estados de desarrollo de C. arcuatus fueron recuperados de los mismos olivares, se confinaron en una jaula de crianza para obtener adultos de la misma edad, los cuales fueron emparejados en unidades de crianza (UC), y colocados en una estufa con aire circulante a 24,2 ± 0,8°C y 36,0 ± 5,9% HR. Diariamente fueron observados hasta su muerte, y a partir de sus posturas se determinó el ciclo de desarrollo que fue de 24 días, de los cuales 3,80; 15,78 y 4,42 días fueron para los estados de huevo, larva y pupa respectivamente. El ciclo biológico de C. arcuatus fue de 77,02 días. La capacidad de oviposición 136,35 huevos/hembra; viabilidad de huevos de 71,43%; mortalidad de larvas 36,25%; capacidad de depredación de LI 3,8 huevos/día, LII 5 huevos/día; LIII 8,2 y 3,6 huevos y ninfas/día respectivamente, LIV 11,4 y 3,4 huevos y ninfas/día respectivamente, adultos 9,8; 4,6 y 1,4 huevos, ninfas y adultos/día respectivamente; proporción sexual 0,59 y la longevidad de 53,02 días.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
