Lab 10 – IPM Fact Sheet

Organizing your ideas handout

Kelsey Galvan

Organizing ideas for your Fact Sheet – 10 points This handout is intended to help you think about what you have learned throughout this course and help you organize your thoughts before you start writing your fact sheet. Most of the information you will need to complete this assignment can be found in your notes, readings, previous assignments, and online resources. Note that we are writing fact sheets for pests that are not currently on the UC IPM, as such you will need to do some research beyond the University of California to get this information. If you are having trouble finding relevant information for your pest in the crop we are looking at, take a look at similar crops that the pest is known to attack.

For example: Suppose you are working on root knot nematode in cannabis, but can’t find any detailed information on how to monitor for it. Take a look at how root knot nematodes are monitored in similar crops (tomatoes, tobacco, corn, etc.) and make recommendations based on that.

Remember that the source for all information must be cited in your final assignment. So, note any information sources on the sheet. Instructions: For each question, outline the key points in your answer and the evidence you used to develop that answer. Why is the pest you are working with important to California growers? Answer: (intro and distribution) Diptera: Tephritidae The Mexican fruit fly (MFF), Anastrepha ludens (Loew): Being a pest of various fruits, but mainly for citrus and mango. The Mexican Fruit Fly is a threat in Florida because of its huge production of grapefruit. There are fruit fly quarentines in place to keep the spread of the invasive fruit flies; although, many larvae are the ones transported widely in infested fruits. Once the female lays its eggs, up to 40 eggs at a time, the larvae eat the flesh of the fruit, which causes rotting. There are more than 50 host plants at risk including: avocado, peach, persimmon, pomegranate, etc. This pest has been found in Arizona, California, and Texas.

Evidence and citations: Weems, Jr., H., J. Heppner, and G. Steck. 2012. Featured creatures fact sheet: Mexican fruit fly, Anastrepha ludens (Loew) (Insecta: Diptera: Tephritidae). EENY-201. University of Florida. (entnemdept.ufl/creatures/fruit/tropical/mexican_fruit_fly.htm).

What kind of damage does the pest cause in the crop you are working with?

Organizing your ideas handout

Answer: Avocado Females will lay eggs in ripening fruit. Larvae dig into pulp of the fruit for 3-4 weeks, eating the flesh of the fruit and leave a hole causing the fruit to rot

Evidence and citations: South Texas Citrus alert, The Mexican Fruit Fly. Retrieved May 05, 2020, from citrusalert/about-the-mexican-fruit-fly/

What is the pest’s basic lifecycle on the crop? Answer: Eggs are laid in groups of about 10-18 (single fly can lay up to 2, eggs in their lifetime) and hatch after 6-12 days. Larvae will then burrow into the fruit and at maturity they will exit the fruit and burrow into the soil to pupate, since typically the fruit fall to the ground after the fruit fly has entered and done its damage. Adults can survive for almost a full year, but males are able to survive longer sometimes, even 16 months.

Evidence and citations: USDA, Mexican Fruit Fly. Retrieved May 05, 2020, from aphis.usda/aphis/resources/pests-diseases/hungry- pests/mff/mexff

How can the pest be most easily identified? Are there features, behavioral traits, locations, etc. that are useful in identification? Answer: Adults: -bigger than housefly, 7-10 mm long -yellow to brown body and wing coloration -female has long ovipositor (3.35-4 mm long) and sheath relative to body size -wing band color of pale yellow -green eyes Pupae: -tan to dark brownish-yellow -pupate in soil Larvae: -three larval instars -white, cylindrical, elongated, anterior end, tapered at the head end and ends with a pair of mouth hooks Eggs: cylindrical and tapered at one end

Evidence and citations: Weems, Jr., H., J. Heppner, and G. Steck. 2012. Featured creatures fact sheet: Mexican fruit fly, Anastrepha ludens (Loew) (Insecta: Diptera: Tephritidae). EENY-201. University of Florida. (entnemdept.ufl/creatures/fruit/tropical/mexican_fruit_fly.htm).

How is the pest typically monitored? How is sampling usually performed?

Lab 10 – IPM Fact Sheet

Organizing your ideas handout

Answer: If any traces of the fruit fly are found then any hosts trees and plants within a 200-meter radius from where the pest was found will be sprayed with a handheld hose dispensing Spinosad, an organic formulation. It is recommended not to use pesticides, because they may kill beneficial insects.

Evidence and citations:

If there is chemical control – are there practices that growers can use to make their control more sustainable? (rotation, soft chemicals, etc.) Answer: Evidence and citations:

What questions or concerns do you have about completing this assignment?

Just how to set up properly, using the layouts as an example, but with the questions listed have to sort out the right way.

If specific information is necessary to be included on the fact sheet.
