AbstractPhyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), also known as the citrus leafminer, is a serious pest in Citrus Linnaeus (Rutaceae) nurseries in Iran. Few studies have been performed on the life history of this pest on different citrus hosts. In this work, the infestation rate and biological aspects of P. citrella were investigated using four citrus hosts: Valencia orange (Citrus sinensis (Linnaeus) Osbeck), trifoliate orange (Poncirus trifoliata (Linnaeus) Rafinesque), grapefruit (Citrus paradisi Macfadyen), and sweet lemon (Citrus aurantifolia Swingle). Moths preferred laying eggs on leaves with a width ranging from 1–2 cm, and the highest oviposition was observed on the Valencia orange (51.2 eggs/female). The numbers of pupae and infested leaves were significantly higher on C. sinensis and C. aurantifolia. The entire developmental period of the immature stages was 13.8 and 15.4 days in C. aurantifolia and C. sinensis, respectively, while it increased to 21.8 and 24.7 days in C. paradisi and P. trifoliata. The rate of mortality of the immature stage was the highest in these two latter hosts as well (29–31%). Moths showed the highest emergence and longevity on C. sinensis and C. aurantifolia. The results indicate that C. sinensis and C. aurantifolia are susceptible hosts that can be recommended for the mass-rearing of this species in non-chemical pest control programmes.

In a moist environment, a minimum exposure of 120 min. at 110–113°F. is required to destroy pre-adult larvae of the bulb nematode Anguillulina dipsaci (Kühn, 1858) Gerv. and v. Ben., 1859, but progressively shorter exposures are required as the temperature is raised. At 116.5–118.5°F. the lethal exposure is 60 min. and at 118.5–120°F. an exposure of 30 min. is required.In a dry environment exposures of 150 min. to temperatures as high as 140°F. are not lethal to pre-adults and the heat treatment does not affect their ability to induce the characteristic symptoms of infestation in barley seedlings.The pre-adults are more resistant to heat than any other stage in the life history of the nematode.The data suggest that the ineffectiveness of the standard hot water treatment when applied late in the season is due to the fact that the major development of pre-adults takes place after the bulbs are lifted, and also because the masses of dormant pre-adults are often well isolated from the moisture of the bath by the bulb scales and corky basal plates, and are more resistant to heat in a dry, compared with a moist, state. It is recommended that the hot water treatment be employed not later than four weeks after lifting when the lifting is done as soon as the foliage dies down.A pre-soak is suggested as a possible means of increasing the effectiveness of the standard hot water treatment.
