Abstract A trial was established in an irrigated commercial potato field adjacent to a commercial planting of a NatureMark NewLeafⓇ field. Plots were 4-36 inch rows by 25’ in length. Treatments were arranged in a RCB and replicated 4 times. Treatments were applied on 8 & 26 June and 8 July using a CO2 hand held sprayer. Total material per acre was approximately 20 gal applied using 40 psi. CPB populations were very high at this site and late readings are confused by non-random feeding. Yields were not taken.

Abstract Continued failure of most insecticides for control of CPB in the Anoka Sand Plains growing area stimulated further comparisons of biologicals, inorganics, and synthetic materials for CPB management. Soils are sands at this location. Plots were established in an irrigated commercial potato field. The individual plot consisted of 4—25 ft rows with a row width of 3 ft. Treatments were arranged in a randomized complete block design and were replicated 4 times. The grower treated all of the field, including the plots, with Thiodan and Asana XL at 1.0 lb and 0.5 lb Al/acre respectively on 8 Jul and 16 Jul. Plot treatments were applied on 25 Jun, 6 and 19 Jul using a CO2 hand sprayer with about 20 gals total material/acre and 40 psi pressure. Larval ratings and defoliation estimates were taken on 6 and 19 Jul. Vines were killed on 3 Aug and yields collected on 18 Aug. The center 2 rows of each plot were harvested for yield.

Abstract This trial was located in a non-irrigated commercial potato field near Hollandale in southern Minnesota. Plots consisted of a single treatment row 25 ft in length bordered on each side by two untreated guard rows. Plant spacing was 36 inches between rows and 12 inches between plants within rows. Treatments were replicated four times in a completely randomized design. Treatments were applied with a CO2-pressurized backpack sprayer fitted with a single Teejet 8003-E flat-fan nozzle delivering 40 gpa/acre at 35 psi. All treatments were applied on 2 Jul. Spraying conditions were windy, but winds were constant. In evaluating the treatments, direct counts of early instars (first and second) and late instars (third and fourth) were made on every plant in each plot on 3 Jul. The data were subjected to analyses of variance following log10(x +1) transformation.

Sprays of Bacillus thuringiensis subsp. thuringiensis (B.t.t.), which contained the beta-exotoxin, were applied to small-scale field plots of tomatoes infested with the Colorado potato beetle [Leptinotarsa decemlineata (Say)] and to bean plots infested with the Mexican bean beetle (Epilachna varivestis Mulsant). Two parasitic wasps of the family Eulophidae were used in conjunction with the B.t.t. in an effort to reduce beetle populations. Treatments on tomatoes consisted of either B.t.t. alone, B.t.t. plus releases of the egg parasite Edovum puttleri Grissell, E. puttleri releases alone, or untreated controls. Treatments on beans were similar except the larval parasite Pediobius foveolatus (Crawford) was released instead of E. puttleri. Treatments in which B.t.t. was used, either alone or in combination with the parasite, significantly reduced adults and 3rd and 4th instar larvae of both species of beetles. The egg parasite, E. puttleri, was unable to significantly reduce the CPB population by itself, however P. foveolatus was able to significantly reduce both 3rd and 4th instar larval and adult populations of the MBB.

A chimeric construct, containing the synthetic cryIIIA (Btt) gene, the NPTII selectable marker and the uidA reporter gene, was incorporated via Agrobacterium tumefaciens into eggplant, variety Hibush. The synthetic cryIIIA gene, altered at the nucleotide level without changing the amino acids of the toxic protein by J. Kemp of New Mexico State Univ., Las Cruces, is adapted for high expression in plant cells. To verify the transgenic status, GUS assays were performed on over 300 plants, from which 185 were confirmed to be transgenic. Physical incorporation of the chimeric construct was further confirmed by Southern analysis of about 30 transgenic plants; both single and multiple site incorporation of the Btt gene were found. Resistance to Colorado potato beetle (CPB) was assessed by: a) placing egg masses of CPB on leaves of plants grown in the growth chamber; b) placing first-instar larvae on detached leaves; c) observing 173 transgenic plants under field conditions. About 60% of the transgenic plants displayed a very high level of resistance to CPB. No larvae survived on the resistant plants longer than 50–60 hours after hatching. Upon selfing, the transgenic plants with a single construct segregate in the S1 generation in a Mendelian fashion.
