1 Role of Beneficial Insects and Mites in Suppression of Psyllids and Other Citrus Pests Jawwad A. Qureshi and Philip A. Stansly Southwest Florida Research and Education Center
2 Major Pest Threats To Florida Citrus 1 Asian citrus psyllid (ACP)/ Huanglongbing, citrus greening 2 Citrus leafminer (CLM)/ Citrus canker Other significant pests Rust mites, Spider mites, Aphids, Scales, Mealybugs, White flies, Black flies, Thrips, Weevils Biological control is critical for sustainable and economical citrus pest management
3 Presentation Outline Predators and parasitoids of ACP, CLM and other citrus pests common in Florida citrus Augmentation of predators and parasitoids Monitoring (scouting) for natural enemies Impact of natural enemies on ACP and CLM populations What else can we do to enhance biological control, conservation? Conclusions and implications
4 COMMON PREDATORS AND PARASITOIDS
5 Southern 2-spotted ladybeetle Olla v-nigrum Primarily a mite feeder Also feeds on aphids and psyllids Its abundance increased in response to psyllid invasion P. Stansly
6 Multicolored asian ladybeetle Harmonia axyridis An introduced species A good predator of aphids and psyllids Also feeds on mites, scales, mealybugs, leafminers, and eggs and larvae of several other insects R. Venette
7 Blood-red ladybeetle Cycloneda sanguinea Important predator of aphids and psyllids Also feeds on mites, scales, and mealybugs J. P. Michaud
8 Metallic blue ladybeetle Curinus coeruleus Imported from Mexico in 1950s Primarily a scale feeder Also feeds on aphids, and psyllids
9 Little red ladybeetle Exochomus childreni A native species abundant in central Florida Primarily a scale feeder Also feeds on aphids and psyllids J. P. Michaud
10 Lacewings - Chrysopidae Chrysoperla spp. Psyllid Eggs & Nymphs Ceraeochrysa spp. P. Stansly
11 Other Predators Asian cockroach Blattella asahinai Sac spider Pseudomyrmex ants Acrobat ants Crematogaster
12 ACP Parasitoid: Tamarixia radiata: Adult Life Cycle Egg Larva Mummies Pupa Prepupa
13 ACP Parasitoid: Diaphorencyrtus aligarhensis
14 Indigenous Parasitoids of CLM Families: Eulophidae, Encyrtidae, Elasmidae, Eurytomidae and Pteromalidae Species LaSalle and Schauff 1996 Cirrospilus nigrivariegatus C. sp. Zagrammosoma americanum Z. multilineatum Pnigalio minio P. sp Sympiesis sp Horismenus sardus Closterocerus cinctpennis Elasmus tischeriae Catolaccus aeneoviridis Schauff et al. 1998, Pomerinke and Stansly 1998
15 Introduced Parasitoids of CLM Ageniaspis citricola Cirrospilus ingenuus From Australia in 1994 Hoy and Nguyen 1994 J. Lotz
16 Introduced Parasitoids of CLM Citrostichus phyllocnistoides From Spain in 2006 Reduced citrus leafminer infestations to non-economic levels in Spain Major role in other Mediterranean countries and in Asia Natives C. phyllocnistoides Vercher et al A. Urbaneja
17 Semielacher petiolatus Another effective parasitoid Plays a major role in Citrus leafminer control in the Mediterranean as well as its native Australia Similar biology to C. phyllocnistoides L. Zappala
18 AUGMENTATION OF PREDATORS AND PARASITOIDS
19 Winter Aggregation of Hippodamia convergens
20 Millions of Hippodamia convergens released in Southwest and Central Florida Commercial Groves ( )
21 Initial releases of T. radiata in Florida , 000 from a mixed colony established at DPI Gainesville, FL, from parasitoids imported from Taiwan and south Vietnam (Hoy and Nguyen 2001, Skelly and Hoy 2004)
22 Our efforts to enhance parasitism rates of T. radiata in the United States Importation and introduction of T. radiata from Pakistan, South China, and North Vietnam (Qureshi and Stansly 2008), and their genetic characterization (Barr et al. 2009) T. radiata released in Florida Florida strain* North Vietnam Pakistan South China *Originally brought in from Taiwan and south Vietnam
23 Citrostichus phyllocnistoides Over 12,000 (4,000 females) released in SW Florida during (Qureshi and Stansly)
24 MONITORING (SCOUTING) FOR NATURAL ENEMIES
25 Monitoring (Scouting) Natural Enemies 1. Tap sample - 22 x 28 cm laminated white sheet of paper - Clipboard or a white smooth surface - Place 1 ft below a leafy branch - Tap branches three times with hand or piece of PVC tube - Count and record insects, spiders, and mites that fall on the sheet - Use black surface when scouting for mites 2. Shoot Observation Shoots infested with aphids, psyllids, leafminers, scales, mealybugs etc. Qureshi and Stansly (2007), Qureshi et al. (2009)
26 Methods to evaluate parasitism rates Cages with apertures to allow parasitoids but not large predacious insects access to colonies in the field. (Michaud, 2004, Qureshi and Stansly, 2009) Examination of nymphs under the microscope to look for parasitoid eggs larvae or pupae (Qureshi et al. 2009) Larva Egg Pupa
27 Methods to evaluate parasitism rates Laboratory rearing of field collected nymphs through adult emergence. (Qureshi and Stansly, 2009, Qureshi et al. 2009) Exposure of plants infested with psyllid nymphs to natural populations of the parasitoid in the field (Qureshi and Stansly, 2009)
28 IMPACT OF NATURAL ENEMIES ON ACP AND CLM
29 Ladybeetle Abundance Before and After Psyllid Invasion in Florida Citrus C. sanguinea H. axyridis O. v-nigrum Other spp. J. P. Michaud (2001)
30 Methods to measure the impact of natural mortality factors on psyllid populations 1. Full cage exclusion 2. Partial cage exclusion 3. Sticky barrier exclusion 4. No exclusion Qureshi and Stansly (2009)
31 Net Reproductive Rate (R 0 ) Impact of natural enemies on psyllid populations Suppression of Psyllid Populations Mainly by Predacious Insects and Spiders (Qureshi and Stansly, Biological Control, 2009) Uncaged Caged Cohort initiation date ( ) R o = Estimated production of progeny from one female psyllid
