1. The document summarizes various insect surveys being conducted in Kansas in 2014, including agroforestry, grape, soybean, and oak pest surveys. Trapping is being done for pests such as the oak ambrosia beetle, processionary moth, walnut twig beetle, summer fruit tortrix moth, and emerald ash borer.
2. Due to reduced funding, the number of grape survey locations was decreased from 56 to 41 sites. Surveys are monitoring for pests including the European grape berry moth and Pierce's disease.
3. The soybean survey is monitoring for pests such as the golden twin-spot moth, old world bollworm, and Egyptian cotton

Bringing Biodiverasity Back to Urban LandscapesPatrick Bohlen
This talk, which I presented in 2017, covers fundamental issues related to loss of biodiversity in urban landscapes, and discusses ways that landscapes can be designed and managed to enhance biodiversity. In a world of increasing urbanization, it will be increasingly imperative to enhance the conservation value of urban landscapes.

ICRISAT sorghum lines demonstrate high resistance to fungal disease in the USAICRISAT
Among 158 sorghum lines that were tested in Pennsylvania for resistance to the fungal disease anthracnose leaf blight, ICRISAT lines, specifically ICSB94, showed the highest level of resistance in the field. These lines are expected to be useful in breeding sorghum for north-eastern United States.With sorghum poised to become an important crop grown by Pennsylvania farmers, Penn State researchers, in a new study, tested more than 150 germplasm lines of the plant for resistance to a fungus likely to hamper its production.
Diversity of plant parasitic nematodes associated with common beans (Phaseolu...Innspub Net
Common beans (Phaseolus vulgaris L.) are the most important legume staple food in Kenya coming second to maize. In Central Highlands of Kenya, the 0.4-0.5ton ha-1 output is below the genetic yield potential of 1.5-2ton ha-1 partly due pests and diseases. Plant parasitic nematodes (PPN) have been reported to cause yield losses of up to 60% on beans. Though bean production is important in the Central highlands of Kenya, information on PPN associated with the beans in the region is lacking. This study was therefore undertaken to establish the diversity of PPN associated with common beans and to assess the root knot nematode damage on beans in the region. The study covered 50 farms (32 in Kirinyaga and 18 in Embu Counties) distributed in eight localities namely Kibirigwi (L1), Makutano (L2), Kagio (L3), Mwea (L4) and Kutus (L5) in Kirinyaga County and Nembure (L6), Manyatta (L7) and Runyenjes (L8) in Embu County and covering three Agro Ecological Zones (AEZs); UM2 (L1, L2, L3 & L4), UM3 (L5, L7 & L8) and UM4 (L6) AEZs. Manyatta (L7) and Nembure (L6), had the highest and second highest gall indices, respectively, while Kibirigwi (L1), Makutano (L2) and Mwea (L4) had some of the lowest gall indices. The most common PPN in bean roots were Meloidogyne spp. Pratylenchus spp. and Scutellonema spp. with a frequency of 94.38%, 78.25% and 59.13%, respectively. This further confirm the importance of these nematodes in bean production systems. Upper Midland 3 (UM3) AEZs and UM4 had higher nematode population densities and diversity than UM2. Disease severity and nematode composition and distribution were notably low in the irrigated areas Kibirigwi, Kagio and Mwea compared to rain-fed areas such as Makutano, Nembure and Manyatta.
Chemical and ecological control methods for Epitrix spp.GJESM Publication
Very little information exists in regards to the control options available for potato flea beetles, Epitrix spp. This short review covers both chemical and ecological options currently available for control of Epitrix spp. Synthetic pyrethroids are the weapon of choice for the beetles. However, the impetus in integrated pest management is
to do timely (early-season) applications with something harsh which will give long-term protection at a time when there are not a lot of beneficials in the field. Finding the balance for control of Epitrix spp. is proving difficult.
Grain mold, considered the most important disease of sorghum, is associated with several fungal genera. The disease reduces both yield and quality. In this study, over 300 sorghum seed samples collected from Texas, Florida, and Georgia were evaluated for grain mold severity, seed weight, germination rate, and seed fungal community. Grain mold severity of the seed samples, except for those collected from Cameron, Texas, were rated 3 or higher, indicating that these sorghum lines were moderately susceptible under naturally-infected field conditions during the 2016 and 2017 growing seasons. Seed weight across surveyed locations ranged from 1.1 g to 4.0g for samples collected in Texas during the same period. Percent germination rates for samples collected in Texas ranged from 59.6% to 86.7%. Sorghum samples collected from Florida and Georgia exhibited moderately susceptible response to grain mold infection. Mean seed weight was 1.9 g for samples collected from Florida, while in Georgia, mean seed weight was 2.3 g. Germination rate was low for samples collected from Florida and Georgia. Mycological analysis of sorghum seed samples collected from farmers’ fields in Central and South Texas during the 2016 and 2017 growing seasons showed Alternaria species as the most frequently isolated fungal genus, accounting for 40% and 42 % in 2016 and 2017, followed by Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex. In Florida and Georgia, Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex was the most frequently recovered fungal species, accounting for 77% and 72% of the total. genera/species isolated from seed samples. Other fungal species, including Curvularia lunata, Bipolaris sp., Colletotrichum sublineola, F. verticillioides, Penicillium sp., Aspergillus flavus, F. thapsinum, F. oxysporum, F. sporotrichioides, F. graminearum, F. proliferatum, and Aspergillus niger were also isolated from sorghum seeds in various frequencies. In conclusion, the presence of large number of fungal genera associated with grain deterioration and their effect on other traits, makes management of this disease complex challenging. To identify grain mold resistant sources in a region, using the most dominant species in that region to screen the sorghum germplasm is recommended.

The Cooperative Agriculture Pest Survey (CAPS)
program conducts science-based national and state
surveys targeted at specific exotic plant pests,
diseases, and weeds identified as threats to U.S.
agriculture and/or the environment. These activities
are accomplished primarily under USDA funding that
is provided through cooperative agreements with state
departments of agriculture, universities, and other
entities. Surveys conducted through the CAPS
program represent a second line of defense against
the entry of harmful plant pests and weeds.
Under the Farm Bill, the Animal Plant Health
Inspection Service (APHIS) will provide funding to
strengthen the nation’s infrastructure for pest detection
and surveillance, identification, and threat mitigation,
while working to safeguard the nursery production

Agroforestry Pest Survey –Farmbill
First year of the survey
Oak ambrosia beetle (Platypus quercivorus) will be trapped using a Lindgren funnel trap with a wet
cup (25% propylene glycol) using a Platypus quercivorus lure. The oak ambrosia beetle, a wood
boring ambrosia beetle, is considered a significant pest of oaks in Japan. The beetle vectors a
fungus Raffaelea quercivora; recent studies have shown that the cause of Japanese oak tree
mortality is the blockage of the ascent of sap induced by the fungus which is transmitted by the
insect.
Oak processionary moth (Thaumetopoea processionea) will be trapped using a wing trap using a
Thaumetopoea processionea lure. Trapping will begin in July -October. The traps will be checked
and specimens collected every two weeks throughout the survey season. The Oak Processionary is
a moth whose caterpillars are pests in oak forests.
Walnut twig beetle (Pityophthorus juglandis) will be trapped for using four funnel Lindgren traps with
a wet cup (25% propylene glycol) and walnut twig beetle lure. The trapping will follow the Thousand
Cankers Disease Survey Guidelines
Grape Survey – Farmbill
Second year of the survey
Due to a reduction in funding the number of locations trapped has been reduced from 56 locations in
2013 to 41 locations in 2014. The survey will entail surveying grape producers in Atchison, Douglas,
Geary, Jefferson, Johnson, Leavenworth, Lyon, Miami, Osage, Pottawatomie, Shawnee,
Wabaunsee and Wyandotte counties with one seasonal staff.
The objective of this survey is to determine if summer fruit tortrix (Adoxophyes orana), silver Y moth
(Autographa gamma), European grape berry moth (Eupoecilia ambiguella), European grape vine
moth (Lobesia botrana) and Egyptian cottonworm (Spodoptera littoralis), Cotton cutworm
(Spodoptera Litura), Pierce’s Disease (Xylella fastidiosa) and Australian grapevine yellows
(Candidatus Phytoplasma australiense) have been introduced into Kansas vineyards.

Soybean Commodity Survey
First year of the survey
This detection survey will gather data to determine the status of the summer fruit tortrix moth, silver y
moth, golden twin spot moth, old world bollworm and Egyptian cottonworm.
Summer Fruit Tortrix Moth (SFTM) - Adoxophyes orana will occur from June to August at or within
the edge of fields of soybeans. Damage occurs as the larvae feed on the leaves and fruit of the
plant.
Silver Y Moth – Autographa gamma will occur from June to August at or within the edge of fields of
soybeans. Caterpillars feed primarily on the leaves. Autographa gamma and other unidentified
Autographa species have been intercepted hundreds of times at U.S. ports. A. gamma is not
established in the U.S.
Golden twin-spot moth – Chrysodeixis chalcites will occur from June to August at or within the edge
of fields of soybeans. Larvae feed on leaves and fruit of their host plants. One specimen has been
found on Pelargonium (geraniums) in an Ohio greenhouse (USDA-APHIS-PPQ). No further
infestation has been detected.
Old World Bollworm – Helicoverpa armigera will occur from June to August at or within the edge of
fields of soybeans. . Larvae feed on leaves and fruit of their host plants.
Egyptian Cottonworm – Spodoptera littoralis will occur from June to August at or within the edge of
fields of soybeans. Early instars feed in groups on leaves, later instars (4-g) disperse to feed.
EAB Trap Trees
Second year of the survey
All the trap trees have been set in the Kansas City Metro area. We set 10 total, 4 in Johnson
County, 3 in Douglas County, 2 in Leavenworth County, and 1 tree at Wyandotte County lake. In
Johnson County, there is effectively 3 locations since 2 smaller trap trees are located very near each
other. Purple prism traps were placed in the girdled trees in Johnson County. We will be visiting
each tree monthly to check and replace the Tanglefoot. Tree removals will likely start in September.
EAB Purple Prism Traps
Ongoing Survey
Plant Protection and Weed Control (PPWC) set and will maintain 82 purple prism traps during the
2014 survey season. Kansas Department of Agriculture (KDA) will be trapping Barton, Bourbon,
Douglas, Ellsworth, Leavenworth, Marion and Osage counties.
