The role of spiders as predators of two lepidopteran Brassica pests
- Biology
- 2016
Three most commonly occurring spider families were found to be capable of feeding on larvae of the diamondback moth, Plutella xylostella, and cabbage cluster caterpillar, Crocidolomia pavonana (Fabricius), under laboratory conditions.
Extreme Susceptibility of Hibana futillis1 Spiderlings to Selected Insecticides2 in a Laboratory Bioassay
- Biology
- 2009
Five commonly used insecticides were compared for toxicity to Hibana futilis, a spider that causes significant mortality of the eggs of bollworm, Helicoverpa zea (Boddie), and beet armyworm, Spodoptera exigua (Hübner), in south Texas cotton (Pfannenstiel 2004, 2005, 2008).
Oophagy in spiders: consumption of invertebrate and vertebrate eggs
- BiologyThe Journal of Arachnology
- 2022
It is demonstrated that oophagy in spiders is much more widespread than previously thought, both geographically and taxonomically, and the finding that spiders feed on eggs/embryos from so many different invertebrate and vertebrate taxa is novel.
Importance of predation by Coleomegilla maculata larvae in the natural control of the corn earworm in sweet corn
- Biology
- 2009
The results of this study suggest that C. maculata larvae are an irreplaceable source of natural mortality for H. zea eggs on sweet corn.

REVIEW Plant-eating by spiders
- Environmental Science, Biology
- 2016
Spiders, a group of predominantly insectivorous predators, occasionally use plant food to supplement their insect prey. In the current review, we tracked down 95 reported incidents of spiders feeding…
Interactions of transgenic Bacillus thuringiensis insecticidal crops with spiders (Araneae)
- Biology
- 2011
It is revealed that foliar spider abundance is unaffected by Bt corn and eggplant, while cotton and rice revealed minor negative effects and there were positive effects from potato, and Bt crops had higher populations of both foliar and epigeal spiders than insecticide-treated non-Bt crops.

Searching Responses of a Hunting Spider to Cues Associated with Lepidopteran Eggs
- BiologyJournal of Insect Behavior
- 2012
Results show that C. inclusum responds to kairomones left by ovipositing H. zea and use these chemical cues to detect and locate H.Zea eggs.

Nocturnal predation of lepidopteran eggs in south Texas cotton - 2002
- Environmental Science
- 2004
Of the predators observed feeding nocturnally, only Solenopsis invicta has been studied as a predator of lepidopteran eggs, little or nothing is known about the predatory characteristics of the other taxa.
Mortality of Helicoverpa zea (Lepidoptera: Noctuidae) Eggs in Cotton as a Function of Oviposition Sites, Predator Species, and Desiccation
- Biology
- 1994
Seasonal predation rates of Helicoverpa zea zea (Boddie) eggs on cotton plants were determined by placing 32P-labeled moth eggs on different types of plant structures throughout the vertical strata of cotton plants and ground based predators added significantly to egg predation.
PREDATORS OF BUDWORM/BOLLWORM EGGS IN COTTON: AN IMMUNOLOGICAL STUDY
- Biology
- 1998
Species of predators sampled in a 30-acre cotton field during the 1996 growing season and assayed for the presence of heliothine egg protein yielded the majority of positive responses, but abundance of cotton aphids relative to heliOTHine eggs during aphid outbreaks may have negative consequences for the efficacy of natural enemies against heliothsine eggs.

Lycosidae, Clubionidae, Oxyopidae, Salticidae and Thomisidae have the capacity to contribute to control of Helicoverpa spp.
Identification and Diel Activity Patterns of Predators Attacking Helicoverpa zea (Lepidoptera: Noctuidae) Eggs in Soybean and Sweet Corn

The complex of predators feeding on lepidopteran eggs [Helicoverpa zea (Boddie)] and the key predators discovered in this study were different in each crop and the period of peak egg predation did also.
Spiders (araneae) as potential predators of leafroller larvae and egg masses (lepidoptera: Tortricidae) in Central Washington apple and pear orchards
- Biology
- 2002
Eleven species of arboreal, hunting spiders, common in central Washington apple and pear orchards, were evaluated as potential predators of the tortricid leafrollers, Pandemis pyrusana Kearfott and…
Predation of Heliothis virescens (F.) Eggs on CoUon in East Texas
- Environmental Science
- 1982
Predator efficiency values were calculated for several species or groups of species and presented as number of eggs individually consumed per 24 h, and revealed a seasonal mean of 137:1 (predator-to-egg ratio).
Nocturnal predators and their impact on lepidopteran eggs in annual crops: what we don't see does help us!
- Environmental Science
- 2005
Nocturnal and nocturnal predators of particular importance included a group of cursorial spiders responsible for nearly 25% of all observations of predation in cotton as well as the formicids (primarily Solenopsis invicta Buren) of the four spider species most frequently observed feeding on eggs.
Nectar Feeding by Wandering Spiders on Cotton Plants

A cold anthrone test to detect the presence of ingested fructose, a plant-derived sugar, in wandering spiders occupying cotton plants, suggests that nectarivory is common for foliage wandering spiders and may contribute to fitness.
Location of Beet Armyworm (Lepidoptera: Noctuidae) Egg Mass Deposition within Canopies of Cotton and Pigweed
- Biology
- 2001
Investigation and quantified placement of egg masses by laboratory colony females within cotton and pigweed canopies of different heights indicate that scouting for egg masses on the underside of leaves in the upper half of the canopy will recover ≈80% of the egg masses present on the plants.
