Mating and oviposition of Earias vittella was studied in the absence or presence of the host (okra fruit) or the host odour. When the host was accessible, there was a significant increase in the frequency of copulation, the number of spermatophores t

Earias vittella (Fabricius) feeds on some malvaceous plant species, but has never been reported to attack Thespesia populnea Cav., even though this plant belongs to the same family. The factors responsible for the failure of E. vittella to establish

Artificial diets were formulated and evaluated for their suitability to rear the spotted bollworm, Earias vittella, a major pest of cotton and okra. The most satisfactory diet consisted of maize semolina 11%, wheat bran 4.6%, soybean powder 2.4%, yea

Influence of age, sex pheromone concentration and mating status on the response of Earias vittella and Earias insulana males to their female sex pheromone was studied using a T-shaped olfactometer. Males of both the species showed age related variati

Through selective screening and breeding, a population of the Trogoderma granarium Everts with reduced male response to the female sex pheromone was isolated. In the eighteenth generation of selection, male response was reduced by 74%, and there was

A study was made of the influence of temperature-induced larval diapause on the response of adult male Trogoderma granarium Everts to female sex pheromone. With increase in time the larvae remained under diapause, post-diapause males showed progressi

Survival and growth of Earias vittella (F.) (= fabia Stoll) on glanded (Gossypium barbadense var. ‘Giza-7’ and G. thurberi) and glandless (G. hirsutum var. ‘Empire glandless’) cotton have been studied. When the larvae were reared on glanded c

The irradiation of eggs and first instar larvae ofCorcyra cephalonica Stainton with beta radiations from P32 has shown that even a dose as high as 3333 mrep/hr. does not produce any detrimental effect on the subsequent development of the parent as we

Two methods of labeling adults of Phanerotoma flavitestacea Fischer (Hymenoptera: Braconidae) with P32 have been compared. Freshly emerged adult parasites fed on honey mixed with P32 acquired radioactivity that was detectable up to 36 days. Longevity

Labelling of the adults ofBracon gelechiae Ashmead by allowing them to feed on 10 per cent. glucose solution containing phosphoric acid (H3PO4) with P32 is not practicable as the adult parasites are unable to pick up enough radioactivity. On the othe
