Adult populations ofMaladera matrida Argaman (Coleoptera: Scarabaeidae), a beetle highly injurious to agricultural crops, were studied in the coastal plain of Israel from 1985 to 1988. There were two generations annually. Adults emerged in March, April or May and disappeared in October or November. The beetles are on the wing, mate, and feed at twilight and in the dark. Feeding and mating behavior, sex ratio, and preferred food plants were studied. 相似文献

A study was carried out to determine the distribution of feeding and oviposition punctures made byLiriomyza trifolii Burgess on gypsophila(Gypsophila paniculata ) and bean(Phaseolus vulgaris) leaves, and the development times of the immature stages on these plants. The absolute number of punctures per leaf area
was much greater on bean leaves than on gypsophila leaves. The number of mines per leaf was also higher on beans than on gypsophila,
but the ratio of mines/punctures was higher on gypsophila. Gypsophila leaves were punctured on both sides, but most of the
punctures were on the distal third of the upper leaf side. On beans the punctures were dispersed uniformly on the upper side
of the leaf. The larval period (±SE) at temperatures of 20, 25 and 30°C was 9.9±0.2, 4.4±0.1 and 3.7±0.1, and 5.5±O. l, 3.7±0.1
and 2.4±0.1 days, on gypsophila and bean, respectively. The pupal period at 17, 20, 25 and 30°C lasted 19.9±0.2, 14.7±0.1,
10.4±0.1 and 7.8±0.1 days, respectively. 相似文献

The effects of γ-radiation on the immature stages ofLiriomyza trifolii Burgess were studied with doses of 2000-25 Gy. The high doses were lethal to all stages. At doses of 750 Gy or less, larvae
survived to pupate, but their number was reduced and the majority were either dead or deformed and did not give rise to adults.
Eggs and prepupae were more susceptible to radiation than other stages. Larval radiosensitivity decreased with progressing
instar, and pupal sensitivity decreased with increasing age.

The bulb miteRhizoglyphus robini Claparède is a soil pest of onion and garlic in Israel. We assayed its control by solar heating of the soil, by means of mulching with transparent polyethylene. Laboratory-infested peanut seeds were buried to various depths either in non-mulched or in mulched soil. At depths of 10 and 20 cm all mites died within 10 days; at 30 cm most mites died after 20 days and complete mortality occurred after 30 days. 相似文献

A study was carried out to determine the optimal height, position (angle) and direction of yellow sticky traps for maximum
attraction ofLiriomyza trifolii flies above gerbera plants. Catches at 30 cm above the plant tops were greater than at 70 cm above the tops. Horizontal and
45° angle traps caught larger numbers on the upper side, whereas with vertical traps there was no effect of side. Catches
on vertical traps were greater than those on horizontal and 45° angle traps. Free-hanging vertical traps caught more flies
than fixed traps facing north and south.

Spodoptera littoralis moths were collected from two mercury vapor light traps in Israel, sexed, and the females dissected to establish the number of times each had mated. The sex ratio was in favor of males. The higher the percentage of males in the trap, the higher was the corresponding percentage of mated females and number of matings per female. MostS. littoralis females mated more than once. The mating status varied with location and season. 相似文献

The effect of low doses of gamma radiation applied toLiriomyza trifolii Burgess eggs or 1st-instar larvae, on the ensuing flies was studied. Doses of 50 or 40 Gy resulted in very few individuals
reaching the adult stage; the life span of these flies was very short and they did not breed. A 25-Gy dose applied at the
1st instar allowed the development of many individuals into adults which emerged successfully, fed, and oviposited viable
eggs which completed their development to adults.

In laboratory populations ofEarias insulana Boisduval (Lepidoptera: Noctuidae) crowding did not affect spermatophore production by males or its acceptance by females. Sex ratio affected spermatophore transfer. A low male: female ratio resulted in the transfer of a large number of spermatophores per male. On the other hand, a high male: female ratio resulted in a high mating frequency of females. Egg production and hatching were not affected. 相似文献
