This presentation was made at various peanut production meetings in Alabama as an annual training on pest management.

1. PEANUT IPM UPDATE, 2010 Dr. Ayanava Majumdar Ext. Entomologist, State SARE Coordinator Gulf Coast Research & Ext. Center 8300 State Hwy 104, Fairhope AL 36532 Tel: (251) 331-8416 bugdoctor@auburn.edu

2. Topics for discussion Research results Insect detection and monitoring project Focus on reported outbreaks in 2009 Updates to the Peanut IPM Guide (IPM-0360) Thrips biological control research IPM-CORE: providing new thrust to IPM via integrated information delivery

3. Program objectives Research components: Efficacy of pheromone traps as a early detection tool (short-term) Impact of weather on insect abundance/activity (medium-term) Develop site-specific forecasting system (long-term) Educational components (based on needs assessment): Early warning system for growers/consultants/Agents (short-term) Increase adoption of pheromone traps (medium-term) Thrust to vegetable/peanut IPM via IPM-CORE (long-term) Funding (2009): Extension IPM Initiative, SPRI/NPB 2010: Specialty Crops Block Grant, SPRI/NPB?, Ext IPM?

6. Trapping period: June-October

8. Trap catches in 2009 Insect catches (June-Oct.): Total = 8,586 High Lesser cornstalk borer (LCB) = 3,586 Fall armyworm (FAW) = 1,386 Beet armyworm (BAW) = 1,377 Corn earworm (CEW) = 589 Southern armyworm (SAW) = 393 Tobacco budworm (TBW) = 342 Soybean looper (SL) = 230 Cabbage looper (CL) = 223 Corn rootworm (CRW): Southern = 253; Western = 13 Black cutworm (BCW) = 125 Stink bugs (SB, Euschistus) = 0* Low * Trap damaged at many locations ** Traps added late (July-Oct.)

9. What is it? HINT: Several outbreaks of these insects occurred in AL, 2009

24. Corn rootworm 4 June WCRW SCRW 28 3 WCRW 8 1 WCRW 12 June, July 2 7 June 1 4 Source: K. Flanders (2010) 1 June Year 2009

25. Impact of Weather on Trap Catches Sign. Correlation of TEMPERATURE : Year 2009 RAINFALL Sign. Correlation of RAIN DAYS : Numbers indicate significant correlations at P = 0.10. +/- indicates direction of relationship (preliminary findings). Rain days indicate number of days rainfall exceeded 0.1 inch.

27. Unusually high trap catches: FAW, BAW, LCB

28. Outbreak reports (2009): FAW, BAW, LCB, CRW

29. Outbreaks consistent with high trap catches

32. Peanut variety: Georgia green

33. Insecticides tested:

34. Temik (aldicarb) @ 0.5 lb AI/acre

35. Thimet (phorate) @ 0.38 lb AI/acre

36. BotaniGard ES (Beauveria bassiana) @ 1-2 quart/acre

37. QRD452 (Chenopodium) @ 1-2 quart/acre

38. Radiant (spinetoram) @ 4-8 oz/acre

39. Thrips sampling: foliar sampling 7 DAT using bags

41. Thrips biocontrol test, Fairhope TSWV vs. healthy peanut plant

42. Thrips biocontrol test, Fairhope 3 5 6 7 2 4 1 Untr. check: 40 thrips/plot, 2-7 virus hits per 60 ft row

43. Thrips biocontrol test, Fairhope 1 Spinetoram(split applications) + phorate (both ½ rates) 6 thrips/plot…no benefit if applied at full rate Fast knockdown product…less virus hits

44. Thrips biocontrol test, Fairhope 2 1 Beauveria(split appl.)+ phorate (both ½ rates) 35 thrips/plot…reduces by ½ if 2x rate is applied Slow product…virus hits increase

45. Thrips biocontrol test, Fairhope 2 1 QRD 400 (split appl.) + phorate (both ½ rates) 29 thrips/plot…reduces by ½ if 2x rate is applied Slow product…virus hits increase

46. What is it? Three-cornered alfalfa hopper Outbreaks in Clarke, Washington, Baldwin, Mobile Co. (2009)

47. Burrower bugs Six species in peanuts, Pangaeusbilineatus most prevalent, sporadic late-season pest Host range: peanut, cotton, strawberry, spinach, wild plants Identification: small insects, note wing structure & spines on legs Overwintering stage: adult, under rocks, crop stubble, volunteer plants Management: Problem in high residue fields Increasing problem as pods fill (late season) Use pitfall traps to determine activity Chlorpyrifos is the only recommended i-cide Hemiptera: Cydnidae

48. What is it? Velvetbean caterpillar Outbreaks in pockets in many Baldwin and Mobile Co. (2009)
