Field Cage Evaluation of Predators of the Soybean Looper, Pseudoplusia includens (Lepidoptera: Noctuidae) 12

Predation of the Chinch Bug, Blissus occiduus Barber (Hemiptera: Blissidae) by Geocoris uliginosus (Say) (Hemiptera: Lygaeidae)

“…Our results (first and second generation) support the hypothesis that big-eyed bugs consume larger numbers of early instar chinch bugs than later instars or adults. These results support the observations of Richman et al (1980) who reported that consumption of small soybean looper larvae, Pseudoplusia includens (Walker), was highest for both G. punctipes and G. uliginosus. Similarly, Medal et al (1995) suggested the higher mortality of the smaller nymphal stages (1 st through 3 rd ) of Spissistilus festinus by G. punctipes was due to their high susceptibility to big-eyed bug attack.…”

Suppression ofBactrocera oleae(Diptera: Tephritidae) pupae by soil arthropods in the olive grove

“…), represented essentially by nocturnal hunters that move very fast on the ground and that were reported to forage actively for larvae and eggs of Diptera, other spiders, Thysanoptera, Hemiptera and Coleoptera (Richman et al. ; Chatzaki ). Lycosidae includes both diurnal and nocturnal active hunters with a wide range of prey in their diet such as dipterans and collembolans (Nyffeler and Benz ; Allen and Hagley ) and that rely on vibratory and visual stimuli to locate and detect prey (Rovner ; Persons and Uetz ).…”

Identification and Diel Activity Patterns of Predators AttackingHelicoverpa zea(Lepidoptera: Noctuidae) Eggs in Soybean and Sweet Corn

“…Studies have attempted to identify predators attacking lepidopteran pests in Þeld crops such as corn, Zea mays (L.) (Andow 1990), cotton (Gossypium hirsutum L.) (Whitcomb and Bell 1964, Whitcomb 1967, McDaniel and Sterling 1979, Nuessly and Sterling 1994, Ruberson and Greenstone 1998, and soybean, Glycine max (L.) [Leguminoseae] (Buschman et al 1977, McCarty et al 1980, Richman et al 1980, Godfrey et al 1989). However, studies that used direct observation (Whitcomb andBell 1964, Buschman et al 1977) inadequately addressed nocturnal predation, and studies using radioactive labeling may produce biased results due to intraguild predation (i.e., predation on predators) (McCarty et al 1980).…”
