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. -

They display remarkable social organization that has enabled them to be ubiquitous throughout the world. They make up approximately 10% of the world’s animal biomass. Ants provide ecosystem services in agrosystems by playing a major role in plant pollination, soil bioturbation, bioindication, and the regulation of crop-damaging insects. Over recent decades, there have been numerous studies in ant ecology and the focus on tree cropping systems has given added importance to ant ecology knowledge. -

Diagonal 645, 08028 Barcelona, Spain – [email protected] Abstract: A checklist of 43 Heteropteran species collected in the area of influence of Can Coll School of Nature is given. By its rarity in the Catalan fauna, the mirid Deraeocoris (D.) schach (Fabricius, 1781) and the pentatomid Sciocoris (N.) maculatus Fieber, 1851 are interesting species. Plus being rare species, the mirid Macrotylus (A.) solitarius (Meyer-Dür, 1843) and the pentatomid Sciocoris (S.) umbrinus (Wolff, 1804) are new records for the Natural Park. The mirids Alloetomus germanicus Wagner, 1939 and Amblytylus brevicollis Fieber, 1858, and the pentatomid Eysarcoris aeneus (Scopoli, 1763) are new contributions for the Park checklist. The Heteropteran richness of Can Coll suggests them as study group for the environmental education goals of this School of Nature.

AND THEIR EGG PARASITOIDS IN RICE AT SABOUR, BIHAR Vikas Kumar and Tarak Nath Goswami* Department of Entomology Bihar Agricultural University, Sabour, Bhagalpur-813210, Bihar (India) *E-mail: [email protected] BAU COMMUNICATION NUMBER: 831/200825 Abstract: A study on diversity of Leptocorisa spp. and their egg parasitoids in rice at Sabour, Bihar, India was conducted in the year 2019. The study revealed that two species of rice earhead bugs, namely, Leptocorisa oratorius (Fabricius) and L. acuta (Thunberg) prevailed in the location of the study. However, more than 90 percent of the Leptocorisa were oratorius. Two egg parasitoids of Leptocorisa, namely, Gryon sp. and Ooenocyrtus along with field parasitisation rates are also being reported from the same location through the present study. Keywords: Leptocorisa, Parasitoids, Rice, Bihar. Introduction Paddy, Oryza sativa, is infested by more than 128 insect pests (Kalode, 2005) and rice gundhi bug Leptocorisa spp. (Hemiptera: Alydidae) are one of the important grain sucking pests among them. They also are among the few pests which feed directly on the spikelet of paddy. Therefore, they are probably the most recognized insect pests by farmers. The crop failure by Leptocorisa in tropical Asia was reported from Java in 1878 by Koningsberger for the first time. As far as India is concerned, Lefroy, in 1908, first reported the Leptocorisa outbreak in paddy. It has been reported that out of the nine species of Leptocorisa, in Asia and Oceania, L. -

Abundance and species diversity of predatory arthropods inhabiting rice of refuge habitats and synthetic insecticide application in freshwater swamps in South Sumatra, Indonesia. Biodiversitas 20: 2375-2387. Rice cultivation in freshwater swamps in Indonesia is specific, among other things, there is no synthetic pesticide spraying and vegetable growing on rice field embankments. This specific cultivation technique can affect the abundance and diversity of rice-dwelling arthropods species. The study aimed to compare the abundance and species diversity of predatory arthropods inhabiting rice surrounded both by refugia and vegetables and by those being applied with synthetic insecticide in the rice field of freshwater swamps.
