It's not too late to mix things up this year, by bringing one of many creative fruit and vegetable goodies to your spooky bash.
What about healthy ideas for children's parties? Think outside the wrapper! Consider handing out non-food items this Halloween. You can purchase many of these items for the same price as sweets. Pro tip: check out your local dollar store or hit up the party favor aisle at most department stores for bulk buys at low prices.
Here are a few non-food ideas:
- Spider rings
- Bouncy balls
- Sidewalk chalk

Two creative and healthful Halloween party ideas.
Light brown apple moth is currently under a California Department of Food and Agriculture quarantine that regulates the interstate shipment of plants to keep the moth from spreading to new areas. It has been quarantined in various counties throughout coastal California ranging from Mendocino to San Diego.
An exotic and invasive pest from Australia, light brown apple moth has a host range of more than 2,000 plants. It is a pest to a wide range of ornamental and agricultural crops, including caneberries, strawberries, citrus, stone fruit, apples, and grapes. The caterpillars eat leaves and buds, leading to weak or disfigured plants. They also can feed directly on fruit, causing the fruit to be unmarketable.
Correct field identification of the light brown apple moth is the first step in containing the spread of this moth. Unfortunately several other leafroller caterpillars, including the orange tortrix, omnivorous leafroller, avocado leafroller, and apple pandemic moth, look similar to light brown apple moth caterpillars. This makes photo identification tools that can go into the field with workers, like the Field Identification Guide for Light Brown Apple Moth in California Nurseries, a useful resource for nursery workers.
The field guide was created by Steven Tjosvold, Neal Murray, University of California Cooperative Extension; Marc Epstein, Obediah Sage, California Department of Food and Agriculture; and Todd Gilligan, Colorado State University with the UC Statewide Integrated Pest Management Program (UC IPM).

“It is a classic disconnect,” said Susie Kocher, UC Cooperative Extension advisor in the Central Sierra office. “That's why Cooperative Extension was formed almost 100 years ago. Policymakers could see that research advances weren't being implemented on farms. The same thing has happened in natural resource management.”
For example, Kocher said, scientists have known since the 1960s that systematic fire suppression has many negative consequences, but it took a very long time to get that message into practice by agencies charged with managing wildfire.
“After the Great Burn of 1910, which killed 87 people, there was a public clamor to attack fire and treat it as an enemy,” Kocher said. “We've come a long way since then. Now land managers have a good understanding of how important it is to have low-intensity fire in Sierra forests.”
Fire agencies are now beginning to understand that they must pay attention to technology transfer. Kocher believes UC Cooperative Extension is a logical player in the process.
“Cooperative Extension is the exemplar,” Kocher said. “We try to get new and evolving understanding into the hands of people who use the information to made decisions – not just land managers, but the public and policy makers as well.”
Beginning in 2009, the federal Joint Fire Science Program created 15 regional fire science exchanges to accelerate awareness, understanding and use of wildland fire science. Scott Stephens, professor in the Department of Environmental Science, Policy and Management at UC Berkeley, leads the California consortium. Stacey S. Frederick serves as the consortium's full-time coordinator. Other UC academics involved are Kocher and Yana Valachovic, UCCE advisor in Humbolt and Del Norte counties.
Since its inception four years ago, the consortium has hosted webinars, conferences and symposia, and offered field consultations, field trips, tours, demonstrations and expertise. Another significant role of the group has been distilling academic fire science research reports into easy-to-read one-to two-page research briefs. To date, well over 100 briefs have been written by the consortium on a wide range of topics.
The California Fire Science Consortium maintains a comprehensive website that contains links to the research briefs, webinar recordings and information about upcoming events. The consortium also offers a twitter feed @cafirescience and Facebook page https://www.facebook.com/CaliforniaFireScienceConsortium and you can sign up for their monthly newsletter here.
“Tomato spotted wilt virus spread by western flower thrips is a big problem for peppers,” said Shimat Joseph, UC Cooperative Extension advisor in Monterey, Santa Cruz and San Benito counties. Tomato spotted wilt can cause a plant to produce discolored fruit that is unmarketable and it can kill the plant. Joseph advises pepper growers on integrated pest management methods to control insects.
“We believe it is critical to manage thrips early in the season because when the plants are small, they are more vulnerable,” Joseph said, “and the disease may not show until later in the season.”
He is currently studying the effects of applying insecticides a month after transplanting to discourage thrips from feeding. He also recommends removing weeds, which can host the virus.
There are no federal guidelines for dating food products; 20 states have laws on the books about food dating, but they are inconsistent.
“Dates on manufactured food products usually indicate how long the food can be kept on store shelves for best quality, but it is unrelated to its safety,” Ganthavorn said.
Canned goods past the expiration date are still safe to eat if the can is not dented, rusted or swollen. On the other hand, perishable foods that have not reached the expiration date may not be safe to eat if they were not refrigerated properly.
Improved understanding of the dates on food products can help consumers avoid waste. “Sell by” is simply a guide for grocery stores. “Best if used by” indicates when the product is in optimum condition. “Use by” is a recommendation to consumers to eat the food with top quality and flavor. After these dates, Ganthavorn said, the product may not be at its very best, but it is typically still safe to eat if it has been stored and prepared appropriately. The key is to follow safe food handling and storage guidelines.
