Three species of Tachinidae, namely, Blepharipa zebina (Walker), Exorista xanthaspis (Wiedemann) and Carcelia sp., were found parasitising the larvae of Amsacta albistriga (Walker) in Pavagada taluk, Tumkur district, Karnataka. In addition to these parasites, two predators, viz., Rhynocoris sp. (Hemiptera: Reduviidae) and Anthia sexguttata (F.) (Coleoptera: Carabidae) were also found predating on these caterpillars.Keywords

Field release of the gall fly, Cecidochares connexa (Macquart) (Diptera: Tephritidae) introduced from Indonesia into India in 2002 was made on naturally growing C. odorata (L.) King and Robinson at two locations in Bangalore during July-October, 2005 using different field release methods. Following establishment, the gall fly was observed lo spread to a distance of one kilometer at GKVK and two kilometer at Tataguni village in northeastern direction by the end of second year after release. The gall numbers encountered by an individual in ten minutes, search steadily increased from 2.5 to 98.3 at GKVK and from 1.6 to 156 at Tataguni village. There was 11.61 and 16.72 per cent reduction in plant height. 30 and 60 days after oviposition in galled plants over control. There was significant reduction in number of branches per plant (35.62%), number of panicles per plant (45.43%), number of capitula per panicle (12.07%) and number of seeds per head (10.89%) in galled plants over control in individual oviposition method. In mass cage method, 40.84, 36.48 and 55.42 per cent reduction in plant height, 30, 60 and 120 days after oviposition in galled plants over control was recorded. There was significant reduction in number of branches per plant (65.56%), number of panicles per plant (48.44%) and number of capitula per panicle (58.98%) in galled plants over control.Keywords

Chromolaena odorata (Linnaeus) King and Robinson is a native or tropical America and has become a serious invasive weed in the wet/dry tropics of Western India. Cecidochares connexa (Macquart) (Diptera:Tephritidae) was introduced from Indonesia into India in 2002 for the biological suppression or the weed. A pure culture of the tephritid was established on C. odorata and the biology studied. Eggs were laid inside unopened new leaf buds. The egg incubation period was 5.65±0.67 days. The gall was visible 15 days after oviposition and in 43.95±4.7 days, formation of windows could be seen indicating complete larval development. One to eight larvae were found in each gall. The total developmental period from egg to adult was 64.85±5.12 days. The adults emerged through the windows and peak emergence (70.4%) was at 1000 hours. Adults were active from 0800 to 1400 hours and mated on the day of emergence. Each female on an average laid 81.12±34.03 eggs and the oviposition period varied from 7 to 12 days. Host'specificity tests carried out under quarantine conditions on 7S host plant species belonging to 29 families revealed that the gall fly is capable of feeding and reproducing only on C. odorata.Keywords

Serious and unprecedented infestations by the sugarcane woolly aphid, Ceratovacuna lanigera Zehntner were witnessed on the leaves of 4·9 month old sugarcane crop in Kolhapur and Pune districts of Maharashtra during September-October, 2002. During surveys for natural enemies, seven predators were recorded in Kolhapur, of which Dipha?aphidivora (Meyrick) was observed to be the most promising. In Pune district, only Cheilomenes sexmaculata (Fabricius) was recorded. Limited field releases of the coccinellid, Synonycha grandis (Thunberg) collected from the bamboo woolly aphids at Bangalore and the chrysopid, Chrysoperla carnea (Stephens) were made in a small area at Kolhapur. S. grandis adults and C. carnea eggs were recovered 2 to 3 weeks after release, indicating their survival in the field.Keywords

Chilo partellus (Swinhoe) larvae were found to be parasitised by Cotesia flavipes Cameron and pupae by Tetrastichus howardi (Oliff) and Xanthopimpla stemmator (Thunberg) in Bangalore during February to May, 2001. The extent of larval parasitisation by C. flavipes varied from 3.3 to 24.5 per cent. Pupal parasitisation due to T. howardi and X. stemmator varied from 2.5 to 9.5 and 0 to 10 per cent, respectively.Keywords

The Lakshadweep Islands were surveyed for Aleurodicus dispersus Russell, its host plants and natural enemies during 1999 and 2000. Two aphelinid parasitoids, Encarsia guadeloupae Viggiani (reported for the first time from India) and Encarsia sp. nr. haitiensis Dozier were found in the Minicoy Island in addition to Some predators. Both aphelinids have been introduced serendipitously into our country. Host plants of the whitefly were recorded in Agatti, Kavaratti and Minicoy islands.Keywords

Fecundity studies on Telenomus remus, an exotic parasitoid of Spodoptera litura (Fabricius) indicated that in individual rearing, net reproductive rate was higher (120.53) and the population increased with an infinitesimal rate of 0.399 and a finite rate of 1.491. In group rearing, the corresponding figures were lower, being 65.03, 0.348 and 1.416, respectively. There was a preponderance of females in the individual rearing method, while a balanced sex ratio was obtained in group rearing.Keywords

Life-table of the Mexican beetle, Zygogramma bicolorata Pallister feeding on parthenium leaves, parthenium leaves smeared with sunflower extract, sunflower leaves and sunflower leaves smeared with parthenium leaf extract have been constructed. The longevity and intrinsic rate of natural increase (rm) varied with extract treated and their respective hosts. The intrinsic rate of natural increase did not change considerably when fed on parthenium leaves and parthenium leaves smeared with sunflower extract (rm=0.44). The beetles fed on sunflower leaves (rm=0.37) and sunflower leaves smeared with parthenium extract (rm=0.35) were also not very different. Shorter generation time was obtained when fed with parthenium and parthenium leaves smeared with sunflower extract.Keywords

In a recent issue of the Indian Journal of Entomology, Birah et al. have attempted to defend the occurrence of pollu beetle, a pest of black pepper, in the Andaman and Nicobar Islands (A&N), India, as reported by them in an earlier article in the same journal in 2011. Their most recent article was in response to the counter to their first article by Prathapan in the same journal, wherein he has critically reviewed the literature for the occurrence of the pest, found them wanting in understanding the pest damage, biology and nomenclature, faulted their methodology in assessing the damage and arriving at the insecticide dosage, etc.- Annual Review of Entomology, 2017

Insects nurture and protect us, sicken us, kill us. They bring us joy and sorrow. They drive us from fear to hate, then to tolerance. At times they bring us up short to a realisation of the way the world really is, and what we have to do to improve it. Their importance to human welfare transcends the grand battles we fight against them to manage them for our own ends. Most of us hate them, but some of us love them. Indeed at times they even inspire us.- Internet of Things based Remote Patients Observatory System Using Biomedical Sensors
