Effects of Spinosad and Lambda-Cyhalothrin on Their Targets, Cabbage Looper, Trichoplusia ni and Diamondback Moth, Plutella xylostella, and on Their Non-Targets, Spiders, on Cabbage in South Texas. (December 2007) Rose Wambui Irungu, B.S., University of Nairobi, Kenya Co-Chairs of Advisory Committee: Dr. Tong-Xian Liu Dr. Marvin K. Harris A randomized block experiment was conducted in cabbage fields at Texas Agriculture Experiment Station at Weslaco in the spring and fall 2005 and spring 2006… 
Lethal effects of λ-cyhalothrin and Emamectin benzoate in Plexippus paykulli (Araneae: Salticidae)
It is concluded that although emamectin benzoate is less toxic than λ-cyhalothrin for P. paykulli, it cannot be recommended for IPM programme.
Catalogue of Texas spiders
A compendium of the spiders of Texas with distribution, habitat, collecting method and other data available from revisions and collections, which includes many records and unpublished data (including data from three unpublished studies).


Evaluating trap crops for diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae).
Differences in oviposition between the potential trap crops and cabbage were likely due to host volatiles, leaf morphology and color, or a combination of these factors, rather than to total leaf areas, leaf shape, or plant architecture.
Evaluation of Action Thresholds and Spinosad for Lepidopteran Pest Management in Minnesota Cabbage
Results indicate that a variety of incidence-based action thresholds can be used to ensure the production of high-quality cabbage in the midwestern United States with only minimal applications of spinosad or permethrin.
Toxicity, Persistence, and Efficacy of Indoxacarb on Cabbage Looper (Lepidoptera: Noctuidae) on Cabbage
Two trials conducted under field conditions show that indoxacarb at 0.072 g (AI)/ha rate was effective against T. ni in cabbage, providing marketable cabbage with three applications per season.
Comparative susceptibilities of diamondback moth (Lepidoptera: Plutellidae) and cabbage looper (Lepidoptera: Noctuidae) from Minnesota and south Texas to lambda-cyhalothrin and indoxacarb.
The susceptibility of early instars of diamondback moth, Plutella xylostella (L.), and early (first and second) and late instars (third and fourth) of cabbage looper, Trichoplusia ni (Hübner), from
Two Types of Resistance to the Diamondback Moth (Lepidoptera: Plutellidae) in Cabbage
Resistance to P. xylostella in the lines investigated was due to at least two mechanisms, antibiosis or nonpreference due to extractable compounds present in normal bloom resistant cabbage genotypes, 2503 and 2535, and possible non Preference for glossy-leafed 2518 by neonate larvae, as suggested by the greater dispersal rates of neonates on these plants.
Economic threshold for three species of lepidopterous larvae attacking cauliflower grown in southern Ontario.
Economic thresholds for imported cabbageworm (ICW), Artogeia rapae (L.), cabbage looper (CL), Trichoplusia ni (Hubner), and diamondback moth (DBM), Plutella xylostella (L.), larvae on cauliflower,
Toxicity, persistence and efficacy of indoxacarb and two other insecticides on Plutella xylostella (Lepidoptera: Plutellidae) immatures in cabbage
Results from laboratory bioassays indicate that indoxacarb was highly toxic to P. xylostella larvae through food ingestion, and was as effective as spinosad, and significantly more effective than emamectin benzoate.
Effect of Selected Insecticides on the Natural Enemies Coleomegilla maculata and Hippodamia convergens (Coleoptera: Coccinellidae), Geocoris punctipes (Hemiptera: Lygaeidae), and Bracon mellitor, Cardiochiles nigriceps, and Cotesia marginiventris (Hymenoptera: Braconidae) in Cotton
Lambda cyhalothrin exhibited the greatest toxicity to the natural enemies and Spinosad exhibited marginal to excellent selectivity,but was highly toxic to each parasitoid species and G. punctipes.
The impact of parasitoids on Plutella xylostella populations in South Africa and the successful biological control of the pest on the Island of St. Helena.
Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is the most injurious insect pest of brassica crops throughout the world. In many countries it has developed resistance to
