New Records of Some Pests of the Coconut Inflorescence and Developing Fruit and Their Natural Enemies in Sri Lanka
COCOS, (1987) 5, 39—42 Printed in Sri Lanka New Records of some Pests of the Coconut Inflorescence and Developing Fruit and Their Natural Enemies in Sri Lanka L. C. P. FERNANDO and P. KANAGARATNAM Coconut Research Institute, Lunuwila, Sri Lanka. ABSTRACT A survey was carried out at Bandirippuwa Estate, Kirimetiyana Estate and at Isolated Seed Garden, Rajakadaluwa for the pests of coconut inflorescence and developing fruits. The mite, Dolichotetranychus sp. (Tenuipalpidae) which lives beneath the perianth and feeds on the epicarp, causes considerable damage to the developing fruit. Bi-monthly observations on the intensity of infestation of nuts among different forms of coconut indicated a significant difference among forms in their susceptibility to mite damage. Pseudococcus cocotis (Maskell) (Pseudococcidae), Pseudococcus citriculus Green (Pseudococcidae) and Planococcus lilacinus (Cockereli) (Pseudococcidae), when feeding in large numbers on the peduncle, cause button nut shedding and drying up of the inflo rescence. The parasitoids and predators of these mealybugs recorded for the first time in Sri Lanka are Promuscidea unfasciativentris Girault (Aphelinidae) Platygaster sp. (Platygastridae), Anagyrus sp. nr. pseudococci (Girault) (Encyrtidae) Coccodiplosis sp. (Cecidomyiidae), Cryptogonus bryanti Kapur (Coccinellidae) and Pseudoscymnus sp. (Coccinellidae). Several species of scale insects namely, Coccus hesperidum (Linnaeus) (Coccidae) Aulacaspis sp. (Diaspididae), Pseudaulacaspis cockerelli (Cooley) (Diaspididae), Aoni- diella orientalis (Newstead) (Diaspididae), and Pinnaspis strachani (Cooley) (Diaspididae) are recorded as minor pests of the developing fruits of coconut. Coccophagus silvestrii Compere (Aphelinidae), Scymnus sp. (Coccinellidae), Pseudoscymnus sp. (Coccinellidae) Telsimia ceylonica (Weise) (Coccinellidae), Cryptogonus bryanti Kapur (Coccinellidae) and Cybocephalus sp. (Nitidulidae) are recorded as their parasitoids and predators. These natural enemies are probably responsible for the control of these pests in the field. -

Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis Yasumatsui Takagi (Hemiptera: Diaspididae)
IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae) 18 September 2005 Subgroup Members (Affiliated Institution & Location) • William Tang, Subgroup Leader (USDA-APHIS-PPQ, Miami, FL, USA) • Dr. John Donaldson, CSG Chair (South African National Biodiversity Institute & Kirstenbosch National Botanical Garden, Cape Town, South Africa) • Jody Haynes (Montgomery Botanical Center, Miami, FL, USA)1 • Dr. Irene Terry (Department of Biology, University of Utah, Salt Lake City, UT, USA) Consultants • Dr. Anne Brooke (Guam National Wildlife Refuge, Dededo, Guam) • Michael Davenport (Fairchild Tropical Botanic Garden, Miami, FL, USA) • Dr. Thomas Marler (College of Natural & Applied Sciences - AES, University of Guam, Mangilao, Guam) • Christine Wiese (Montgomery Botanical Center, Miami, FL, USA) Introduction The IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests was formed in June 2005 to address the emerging threat to wild cycad populations from the artificial spread of insect pests and pathogens of cycads. Recently, an aggressive pest on cycads, the cycad aulacaspis scale (CAS)— Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae)—has spread through human activity and commerce to the point where two species of cycads face imminent extinction in the wild. Given its mission of cycad conservation, we believe the CSG should clearly focus its attention on mitigating the impact of CAS on wild cycad populations and cultivated cycad collections of conservation importance (e.g., Montgomery Botanical Center). The control of CAS in home gardens, commercial nurseries, and city landscapes is outside the scope of this report and is a topic covered in various online resources (see www.montgomerybotanical.org/Pages/CASlinks.htm). -
Reaction of the Ladybird Chilocorus Nigritus (F.) (Col., Coccinellidae) To
J. Appl. Ent. 112 (1991), 493-498 0 1991 Verlag Paul Parey, Hamburg und Berlin ISSN 093 1-2048 Department of Zoology and Entomology, University of Natal, Pietermaritzburg, South Africa Reaction of the ladybird Chi’locorus nigritus (F.) (Col., Coccinellidae) to a doomed food resource By C. ERICHSEN,M. J. SAMWAYSand V. HATTINGH Abstract The coccinellid Chilocorus nigritus (F.), a predator of many scale insects, has become an economically important natural enemy of red scale (Aonidzella aurantii [Maskell]) in the subtropical citrus-growing areas of southern Africa. Although relatively easy to mass rear and distribute, there has been speculation that C. nigritus does not exploit fruit with very hi h scale infestations. Experimentation using an alternative prey scale Aspidiotus nerii Bouchi showefi that a ran e of low to medium-high scale population levels supported increasin ly high ladybird densities. At aigh scale densities, where the host vegetable was imminently doomefi, there was a significant drop in beetle densities. At even higher scale densities, where the fruit was already beginnin to rot, there was a return in beetle densities to a level equivalent to that on medium-high scale fiensities. At low to medium-high prey densities, male and female beetles were present in fairly constant proportions. At high prey levels there was an increase in female dominance, yet a strong decrease in dominance at even higher scale levels where the vegetable was already beginning to rot. There appears to be an avoidance of imminent1 doomed vegetable hosts, yet, in contrast, rotting vegetables have some attraction but more so &r males. -

BACKYARD BUDDIES Information Sheet Chilocorus Circumdatus for Scale
BACKYARD BUDDIES Information Sheet Luke - adult & larvae Chilocorus circumdatus for Scale Red Chilocorus (Luke) is a helmet-shaped ladybird beetle, approximately 5 mm in length. Adults are a rich orange colour with a fine black margin around the base of their wing covers. Adult females lay cylindrical eggs, 1 mm in length, beneath the cover of scale insects. At 25˚C the eggs take about one week to hatch. Chilocorus larvae are voracious feeders and have pronounced spines that cover their body. After ten days or so larvae then migrate to a secluded position and pupate. The adult beetles emerge between seven and nine days later, to mate and lay their eggs. Egg laying starts approximately ten days after emergence. At an optimum temperature of 28˚C, their life cycle takes approximately one month. Chilocorus beetles live for between four and eight weeks. Target pests Armoured scale insects, including: Red scale Aonidiella aurantii Oriental scale Aonidiella orientalis Oleander scale Aspidiotus nerii White louse scale (citrus snow scale) Unaspis citri Scale-eating ladybirds prey on a range of armoured scale insects. Red Chilocorus beetles feed readily on white louse scale (citrus snow scale), oleander scale, oriental and red scale. Scale insects feed by sucking sap from plants. A heavy infestation may cause discolouration, leaf drop and shoot distortion, which can lead to twig dieback and even plant death. Chemical control of scale is difficult because they have hard, waxy protective covers and remain stationary for most of their live. The resistance of scale insects to pesticides is a problem in many regions. -

Sison, Joseph P. Lagman, Edward Cedrick J. Fernandez and Hayde F. Galvez Institute of Plant Breeding, College of Agriculture and Food Science, University of the Philippines Los Baños, College, Laguna, Philippines 4031 Corresponding author: [email protected] (Received: October 3, 2018; Accepted: May 19, 2019) ABSTRACT The devastation of millions of coconut palms caused by outbreak infestation of the invasive Coconut Scale Insect (CSI) Aspidiotus rigidus Reyne, has posed a serious threat to the industry in the Philippines. The life history of A. rigidus on coconut and mangosteen was comparatively studied to understand the effects of host-plant species on its development, to investigate potential host-suitability factors that contributed to its outbreak infestation, and to gather baseline information on the development and characteristics of this pest. The study was conducted at the Institute of Plant Breeding, College of Agriculture and Food Science, University of the Philippines Los Baños. Insect size (body and scale) was not significantly different on both hosts during egg, crawler, white cap, pre-second and second instar stages, as well as during male pre-pupal, pupal and adult stages. The female third instars and adults, however, were bigger on mangosteen than on coconut. At the end of second instar, sexual differentiation was very visible wherein parthenogenic females further undergone two developmental stages: third instar and adults that feed permanently on the leaves. Males undergone three stages: pre- pupa, pupa and winged adults. -
