Insecticides were applied with a Bean handsprayer at 400 psi, complete coverage, approximately 1500 gpa. The field was divided into 10 blocks with one replicate of each treatment applied to a single tree within each block. Treatment trees were separated on all sides by single untreated trees. Five twig samples (gray wood indicating 2nd year growth, 23 cm in length) and 5 fruit were collected randomly from each of the sample trees and examined for 1st stage, 2nd stage, virgin and mature female stages of scale. Scale on the fruit were also examined for live larvae and pupae of C. bifasciata and eggs, larvae and pupae of A. melinus. Twig samples were collected pretreatment and both twig and fruit samples were collected 30 and 60 DAT. Leaf drop was measured weekly by counting the leaves that collected on a 60 X 90 cm paper tray placed under the canopy in the north side of treatment trees in five of the blocks. The population of the predatory mite, E. tularensis, was determined by collecting 20 leaves per tree (5 per quadrant) each week in 5 of the blocks until 60 DAT.

Pepper seedlings were obtained from a local grower and transplanted into 6.1 m rows on 6 Jun, with 91.4 cm between row spacing and 35.6 cm between plant spacing. Five treatments were applied to both pepper varieties in a randomized block design with four replications. Treatments were applied to foliage using a hand held CO2 sprayer at 35 psi with a single nozzle at 40 gal/acre. Low corn borer activity led us to artificially infest our plots. European corn borer egg masses were obtained from the Corn Insect Lab at Ankeny, Iowa. Five randomly selected plants per replicate received ECB egg masses. The egg masses were pinned to the underside of the leaf through the mid rib, near a developing fruit. One egg mass per plant was attached 17 Aug and two egg masses per plant were attached 3 Sep. All treatments were applied on 18, 24, and 31 of Aug, and 6 Sep. Orthene 75 SP and MVP were sprayed on alternate weeks, beginning with Orthene 75 SP. Pepper fruits were destructively harvested on 18 Sep. Only peppers from the artificially infested plants were sampled, with no more than five fruit picked per pepper plant. Each fruit was cut open and inspected for ECB larvae. Fisher’s Protected LSD test at β = 0.01 was performed on the percent of pepper fruit contaminated with ECB larvae.","PeriodicalId":13691,"journal":{"name":"Insecticide and Acaricide Tests","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79809867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
